Brexit: first look at Benedict Cumberbatch as Dominic Cummings

Channel 4 is making a one-off political thriller about the Brexit vote, with Benedict Cumberbatch playing a starring role. The Sherlock, Doctor Strange and Patrick Melrose actor will play a real-life political strategist, Dominic Cummings, who was Director of the Vote League campaign.

Today, we have a first-look image to share of Cumberbatch as Cummings…

And here’s a snap of the real-life Cummings, for comparison’s sake…

A decent likeness, isn’t it? It should be interesting to see how the ever-likeable Cumberbatch slips into this role.

Playwright James Graham, who is known for such stage shows as Quiz and The Vote, wrote this new Channel 4 project. The one-part TV show is going by a working title of simply Brexit, and, according to Deadline, it will “unpack the anatomy of the historic, high-stakes campaign to win the hearts and minds of the British people”.

Toby Haynes will direct, building on an impressive CV of TV content which already includes numerous Doctor Who episodes, seven instalments of Jonathan Strange & Mr Norrel,Sherlock’s“The Reichenbach Fall”, Black Mirror‘s “USS Callister”, and many more.

Writer James Graham said this about the project:

“I’m so excited — not to mention a little nervous — to have this chance to try and get under the skin of what happened during that historic vote. I hope by going behind-the-scenes of the campaign, we’re able to interrogate the consequences of what happened during these eight weeks that have changed the country forever. To work with this incredible team and Channel 4 to bring this story to life on screen is a real honour.”

Lesson: How to Calculate Distance and Travel Time

Introduction:
In this lesson, we will learn how to calculate distance and travel time between two locations using real-world scenarios. We will use the example of Grimes, IA and Newton, IA to demonstrate the process.

Section 1: Calculating Distance

Topic 1: What is distance?
Distance is the measurement of how far two objects are apart from each other. It can be measured in miles, kilometers, feet, or any other unit of length.

Topic 2: How do we calculate distance?
To calculate distance, we need to know the latitude and longitude coordinates of the two locations we want to measure the distance between. We can use a map or a GPS device to find these coordinates.

Topic 3: Example
Let's say we want to calculate the distance between Grimes, IA and Newton, IA. The latitude and longitude coordinates for Grimes, IA are (41.7087, -93.5904) and for Newton, IA are (42.3508, -94.0917).

Step 1: Convert the coordinates to decimal degrees.
Grimes, IA = 41.7087° N, 93.5904° W = 41.7087 * (90/180) = 41.7087 * (1.1111) = 45.8005° N
Newton, IA = 42.3508° N, 94.0917° W = 42.3508 * (90/180) = 42.3508 * (1.1111) = 46.7023° N

Step 2: Find the difference in latitude and longitude.
Δlat = 46.7023 - 45.8005 = 0.9018°
Δlong = 94.0917 - 93.5904 = 0.4013°

Step 3: Use the Haversine formula to calculate the distance.
a = sin²(Δlat/2) + cos(45.8005°) * cos(46.7023°) * sin²(0.4013°)
c = 2 * atan2(√a, √(1−a))
d = 6371 * c

The result is approximately 33.6 miles or 54.1 kilometers.

Section 2: Calculating Travel Time

Topic 1: What is travel time?
Travel time is the amount of time it takes to travel from one location to another. It depends on factors such as distance, mode of transportation, and road conditions.

Topic 2: How do we calculate travel time?
To calculate travel time, we need to know the speed at which we are traveling and the distance we need to cover. The formula for calculating travel time is:

Travel Time = Distance / Speed

Topic 3: Example
Let's say we want to calculate the travel time between Grimes, IA and Newton, IA. We know that the distance between the two locations is approximately 33.6 miles or 54.1 kilometers. Let's assume we are driving at an average speed of 60 miles per hour.

Step 1: Calculate the travel time.
Travel Time = 54.1 km / 60 mph = 0.9017 hours = 56 minutes

Conclusion:
In this lesson, we learned how to calculate distance and travel time between two locations using real-world scenarios. We used the example of Grimes, IA and Newton, IA to demonstrate the process. By understanding these concepts, we can better plan our trips and estimate the time and cost required to reach our destinations.

IT (2017) takes place in 1989, twenty seven years after the original IT opening, inline with the Stephen King’s original lore. This film uses modern technology to give IT what it deserves. With much better sound design, acting, special effects, and, most importantly, a bigger budget, IT is most certainly a movie worth watching.. The original IT offered quality storytelling, but few scares. While the child actors were genuinely good, Tim Curry gave off an almost comedic performance. If a scary scene did happen, another scene came along to nullify the effect.. If you want a picture to show with your comment, go get a gravatar.

Title: Understanding Real Estate Markets

## Chapter 1: Introduction to Real Estate Markets

In this chapter, we will learn about real estate markets and their importance in the economy. We will also explore the different types of real estate and the factors that influence their value.

**Section 1: What is a Real Estate Market?**

A real estate market refers to the supply and demand of land, buildings, and other properties in a particular region. It is influenced by various economic, social, and political factors that affect the value of these properties. Real estate markets can be local, regional, or national, depending on the scope of the analysis.

**Section 2: Types of Real Estate**

There are four main types of real estate: residential, commercial, industrial, and agricultural. Residential real estate includes single-family homes, condominiums, townhouses, and multi-family buildings. Commercial real estate consists of office buildings, retail spaces, warehouses, and other properties used for business purposes. Industrial real estate includes factories, manufacturing plants, and other properties used for production and distribution. Agricultural real estate encompasses farmland, ranches, and other properties used for farming and agriculture.

**Section 3: Factors Affecting Real Estate Value**

Several factors influence the value of real estate, including location, demand, supply, interest rates, inflation, and government policies. Location is a crucial factor because it determines the property's accessibility to transportation, schools, shopping centers, and other amenities. Demand and supply determine the price of a property, with higher demand leading to higher prices and vice versa. Interest rates affect the cost of financing, while inflation erodes the value of money over time. Government policies, such as tax laws and zoning ordinances, can also impact real estate values.

**Section 4: Conclusion**

Understanding real estate markets is essential for anyone interested in buying, selling, or investing in property. By studying the different types of real estate and the factors that influence their value, we can make informed decisions about when to buy or sell a property and how much to pay or ask for it. In the next chapter, we will delve into the role of agents and brokers in real estate transactions.

**Glossary**
- Real estate market: The supply and demand of land, buildings, and other properties in a particular region.
- Residential real estate: Properties used for residential purposes, such as single-family homes, condos, townhouses, and multi-family buildings.
- Commercial real estate: Properties used for business purposes, such as office buildings, retail spaces, and warehouses.
- Industrial real estate: Properties used for production and distribution, such as factories and manufacturing plants.
- Agricultural real estate: Properties used for farming and agriculture, such as farmland and ranches.

In the span of five days, the idea of the United States buying Greenland went from one step above rumor to grounds for cancelling a state visit to Denmark.

Talking with reporters on the White House south lawn Wednesday, President Donald Trump said it was “just an idea,” but a good one. He then pivoted to the Danish reaction to the sale of its territory.

“I thought the prime minister’s statement that it was an absurd idea, was nasty,” he said. "All they had to do was say, ‘No, we’d rather not do that,’ or, ‘We’d rather not talk about it.’ Don’t say, ‘what an absurd idea that is.’ Excuse me, she’s not talking to me. She’s talking to the United States of America. You don’t talk to the United States that way.”

Trump was slated to visit Denmark, but tweeted Tuesday, “based on Prime Minister Mette Frederiksen’s comments, that she would have no interest in discussing the purchase of Greenland, I will be postponing our meeting scheduled in two weeks for another time.”

Denmark is a very special country with incredible people, but based on Prime Minister Mette Frederiksen’s comments, that she would have no interest in discussing the purchase of Greenland, I will be postponing our meeting scheduled in two weeks for another time.... — Donald J. Trump (@realDonaldTrump) August 20, 2019

How we got here

On Aug. 16, the Wall Street Journal ran an article citing unnamed administration insiders that Trump was showing an interest in buying Greenland. After coming up in dinner table and hallway discussions, the idea had reached the point, the newspaper said, where Trump had asked the White House counsel to look into it.

At first, there was no official confirmation, but Monday, Trump told reporters, “strategically, it’s interesting. And, we’d be interested. We’ll talk to them a little bit.”

Trump added, "It's not No. 1 on the burner, I can tell you that."

Trump later offered a visual quip on Twitter, posting a photo of a high-rise Trump tower set in a bucolic Greenland village, with the words, “I promise not to do this to Greenland!”

I promise not to do this to Greenland! pic.twitter.com/03DdyVU6HA — Donald J. Trump (@realDonaldTrump) August 20, 2019

Given that the island Danish territory is three times the size of Texas, this would be no incidental American acquisition. Which raises the question, what does Greenland offer that the United States would want?

Pompeo talks shipping, China and Russia

Greenland might have only 56,000 people and be about 80% covered in ice, but the United States sees it as a place to thwart Chinese and Russian interests. A few years ago, Greenland announced plans to build a new airport and expand two others. China stepped in to provide the financing. In 2018, then-U.S. Defense Secretary James Mattis personally intervened.

“When a Chinese state-owned contractor was shortlisted for the airports project, it provoked anxiety both in Denmark and more so in the United States, leading to Denmark stepping in to part-finance and co-own the projects,” said Dwayne Ryan Menezes, managing director of the Polar Research and Policy Initiative, a private research group based in the United Kingdom.

As Arctic sea ice melts, Greenland lies along or near emerging shipping routes, the Northwest Passage and the Northeast Passage. Menezes said it could cut nearly a quarter off the distance a freighter from Shanghai to Rotterdam would need to cover.

At a May 2019 meeting of the Arctic Council, an intergovernmental body, U.S. Secretary of State Mike Pompeo warned of China’s presence and the need to control the shipping lanes.

“Do we want the Arctic Ocean to transform into a new South China Sea, fraught with militarization and competing territorial claims?” Pompeo said.

In the same speech, Pompeo said, “Russia is already leaving snow prints in the form of army boots” in the region.

Pompeo announced the United States would establish a permanent diplomatic presence in Greenland, something it hasn’t had since the 1950s.

Beyond its geo-strategic role, the Arctic is believed to be rich in gas and oil, and Greenland has large mineral reserves.

“As China copes with declining reserves of rare earth elements, Greenland alone has enough to satisfy at least a quarter of global demand in the future,” Menezes said.

Dismissive Denmark

The day that Trump acknowledged his interest, Denmark Prime Minister Mette Frederiksen said, "Greenland is not for sale."

Frederiksen was in Greenland that day and went further, calling it “an absurd discussion.”

“Thankfully, the time where you buy and sell other countries and populations is over,” Frederiksen said. “Let’s leave it there. Jokes aside, we will of course love to have an even closer strategic relationship with the United States.”

Trump noted those words as he told reporters on the White House lawn why he canceled a trip to Denmark planned for early September.

Ice vs. beaches

As Trump and his aides have said, President Harry Truman explored the idea of buying Greenland. In 1946, he offered Denmark $100 million for the world’s largest island. As the Cold War took root, it occupied a central spot between the United States and the Soviet Union. It later became home to a major U.S. Air Force base.

Curiously, the United States’ last land purchase also involved Denmark and an island — actually more than one. The United States bought the Virgin Islands from Denmark in 1917 for $25 million. (Under U.N. auspices, the United States acquired several island groups in the Pacific after World War II, but those were not financial transactions.)

We ran the numbers, and protecting against the threat of the Soviet Union didn’t quite match the appeal of the Virgin Islands. Ignoring inflation, Truman offered about $120 per square mile for Greenland and its ice. In 1917, the United States paid nearly $190,000 per square mile for the Virgin Islands and their beaches.

Since Greenland is not for sale, no firm offer from Trump was put on the table.

1. Field of the Invention
This invention relates to refractory assemblies and components thereof for use in industrial furnace roofs. More particularly, this invention relates to roof assemblies and components particularly suitable for repairing suspended refractory brick roofs.
2. Description of Prior Art
Refractory bricks are used in roof construction of high temperature industrial furnaces such as reverberatory furnaces. In furnace roof construction, the refractory bricks are suspended from a support structure which may be from several inches to about 2 feet above the brick roof. The refractory bricks are suspended from the support structure by various suspending means such as metallic hangers which hold the bricks at one end and hook over the support structure at the other end. Reverberatory furnaces are frequently operated for many years without shutdown. However, the life of the suspended roof which is usually constructed from refractories is from 6 months to 3 years. This makes patching of the roof furnace during operation necessary. Some roof refractory structures are panelized so that entire sections may be removed and replaced, or individual pairs of bricks in the panel may be patched by use of assemblies of this invention. In roofs which are not panelized, the roof is constructed by placement of individual or pairs of bricks. The assembly of this invention may be used, as well, in repair of non-panelized furnace roofs.
The refractory bricks used in high temperature furnace construction have a rectangular cross-section. Normally, in patching refractory roofs, two bricks are assembled with a hanger supporting both bricks in the patching assembly. The cross-section of the patching assembly is rectangular, normally occupying a space of 41/2 by 7 inches. When patching the refractory roof, the opening for the patch assembly may have a long dimension which runs parallel to the longitudinal center line of the furnace or at right angles to it, depending upon the shape of the hole to be patched. The support structure, whether panelized construction is used or individual pairs of bricks are used, normally runs at right angles to the center line of the furnace.
Most patching or repair assemblies previously available, due to the opening being greater in one dimension than the other, require use of two types of assemblies. Since the plane of the hook of the hanger and the long dimension of the brick patching assembly were not rotatable with respect to each other, it has been necessary to provide one assembly with a hanger hook for attachment to the support structure parallel to the long dimension of the patch assembly and one with the hanger hook at right angles to the short dimension of the patch assembly. Therefore, it has been necessary to provide more than the required number of patch assemblies at the job site because it is not usually known until engaging in the repair which way the patch assembly will be introduced into the furnace. One approach to overcoming this disadvantage and utilizing patch assemblies having a hanger with a hook which may be used in both directions has been to provide a hanger with a mushroom-shaped head loosely fitting on the hanger casting recess, thereby allowing the hanger hook to rotate 360 degrees with respect to the bricks. This eliminates the inventory problem, but creates serious disadvantages in use because the refractory is free to rotate on the end of the hanger thereby making it difficult to insert the patch into the hole in the hot furnace roof, especially in cases where the patch must be inserted at an angle. Many of the same problems arise in new furnace construction.
These problems are solved by the industrial furnace roof assembly of our earlier U.S. patent, U.S. Pat. No. 4,073,243 which teaches an industrial furnace roof assembly in which brick pairs are suspended by an assembly of a hanger which mates with voids in both bricks, and a hanger rod which supports the hanger. The hanger has a square, upset-forged head which serves as the bearing surface for the hanger. The hanger rod passes through a hole in the hanger and is bent to form a hook which can be hung from a supporting member such as a pipe. In accordance with the '243 patent, the hanger rod is first passed through the hole in the hanger. The hanger, with the hanger rod engaged, is then seated into the void of one brick. A second brick is placed against the first brick such that the casing and hanger are at the split line of the two bricks. It is very common for an assembly of bricks, hanger and hanger rod to be encased in a steel casing and shipped as a complete assembly.
However, material handling of brick assemblies as taught by the '243 patent is complicated by the irregularity of the assembled brick pair with the hanger rod protruding out from the brick. Special care must be taken during packaging to assure that the bricks are properly supported without damage to the hanger rods. In addition, brick assemblies require more storage space.

Lesson Title: Introduction to Refractory Bricks and Their Applications in Industrial Furnaces

Level: Primary through High School

Overview:
In this lesson, we will learn about refractory bricks, their properties, and their applications in industrial furnaces. We will also explore the challenges associated with their use and the methods used to repair them.

Section 1: Introduction to Refractory Bricks

**Definition:** Refractory bricks are ceramic materials that can withstand high temperatures without undergoing significant structural changes or melting. They are commonly used in industrial furnaces, such as reverberatory furnaces, to line the walls and roofs.

**Properties:** Refractory bricks have several properties that make them suitable for use in high-temperature environments. These properties include:

- High thermal conductivity: Refractory bricks can efficiently transfer heat, making them ideal for use in furnaces where heat is generated.
- Low thermal expansion: Refractory bricks do not expand or contract significantly when exposed to high temperatures, which helps maintain their structural integrity.
- High thermal stability: Refractory bricks can withstand temperatures of up to 3000°F (1650°C) without breaking down or losing their strength.

Section 2: Applications of Refractory Bricks in Industrial Furnaces

**Reverberatory Furnaces:** Reverberatory furnaces are used in various industries, such as steel production and glass manufacturing, to heat materials to high temperatures. Refractory bricks line the walls and roof of these furnaces, providing insulation and protecting them from the heat.

**Challenges:** Despite their advantages, refractory bricks have some limitations. One of the main challenges associated with their use is their relatively short lifespan. The roof of a reverberatory furnace typically lasts between 6 months and 3 years before it needs to be replaced. Additionally, the process of replacing the roof can be time-consuming and costly.

Section 3: Repairing Refractory Brick Roofs

**Methods:** There are several methods for repairing refractory brick roofs, including:

- Patching: This involves filling cracks or holes in the roof with new refractory material.
- Rebuilding: This involves completely replacing the damaged roof with new refractory bricks.
- Relining: This involves installing a new lining of refractory material on top of the existing roof.

**Advantages and Disadvantages:** Each method has its advantages and disadvantages. For example, patching is a quick and cost-effective solution but may not be as durable as rebuilding or relining. On the other hand, rebuilding or relining may be more expensive and time-consuming but can result in a longer-lasting roof.

Glossary:
- Refractory bricks: Ceramic materials that can withstand high temperatures without undergoing significant structural changes or melting.
- Thermal conductivity: The ability of a material to transfer heat.
- Thermal expansion: The increase in volume of a material when it is heated.
- Thermal stability: The ability of a material to maintain its structural integrity at high temperatures.

Conclusion:
In this lesson, we have learned about refractory bricks, their properties, and their applications in industrial furnaces. We have also explored the challenges associated with their use and the methods used to repair them. By understanding these concepts, we can better appreciate the importance of refractory bricks in various industries and their role in maintaining efficient and safe operations.

Lesson: How to Implement a Stack using Linked Lists

Introduction:
A stack is a data structure that follows the Last In First Out (LIFO) principle. It is used to store and retrieve elements in a particular order. In this lesson, we will learn how to implement a stack using linked lists. We will start with the basic concepts and then move on to more advanced topics.

Section 1: Basic Concepts

Topic 1: What is a stack?
- A stack is a collection of objects that follow the LIFO principle.
- It can be used to store and retrieve elements in a particular order.
- Elements can be added or removed from the stack at any time.

Topic 2: Implementing a stack using linked lists
- A linked list is a collection of nodes, where each node contains a value and a reference to the next node in the list.
- We can use a linked list to implement a stack by creating a new node and adding it to the top of the stack.
- To remove an element from the stack, we can remove the top node from the list.

Topic 3: Operations on a stack
- Push: Add an element to the top of the stack.
- Pop: Remove the top element from the stack.
- Peek: Return the top element of the stack without removing it.
- Size: Return the number of elements in the stack.

Section 2: Implementation

Topic 1: Creating a stack class
- Define a class called Stack that contains a linked list to store the elements.
- Add methods to perform stack operations such as push, pop, peek, and size.

Topic 2: Implementing the stack
- Create a new node and add it to the top of the stack.
- To remove an element from the stack, remove the top node from the list.
- To return the top element without removing it, return the value of the top node.

Topic 3: Testing the stack
- Create an instance of the Stack class.
- Call the push, pop, peek, and size methods to test the functionality of the stack.

Section 3: Advanced Topics

Topic 1: Circular Linked Lists
- A circular linked list is a type of linked list where the last node points to the first node.
- We can use a circular linked list to implement a stack by creating a new node and adding it to the top of the list.
- To remove an element from the stack, we can remove the top node from the list.

Topic 2: Doubly Linked Lists
- A doubly linked list is a type of linked list where each node contains two references, one to the previous node and one to the next node.
- We can use a doubly linked list to implement a stack by creating a new node and adding it to the top of the list.
- To remove an element from the stack, we can remove the top node from the list.

Conclusion:
In this lesson, we learned how to implement a stack using linked lists. We started with the basic concepts and then moved on to more advanced topics such as circular linked lists and doubly linked lists. We also implemented a Stack class and tested its functionality. This knowledge can be applied to various programming problems that require the use of stacks.

Cholangiocarcinoma in north east Thailand. A hospital-based study.
The population of Northeast Thailand has one of the highest known rates of cholangiocarcinoma (cancer of the bile ducts). We sought firstly to obtain an estimate of the frequency of hospital-based diagnosis of cholangiocarcinoma in the northeastern province of Khon Kaen. All pathology, ultrasound and in-patient and out-patient records were searched for cases diagnosed in tertiary hospitals in a random calendar month in 1988. A total of 203 persons from various parts of northeastern Thailand were newly-diagnosed in the two hospitals, 75 of whom resided in Khon Kaen province. We estimated the minimal age-standardised annual incidence rate in this province to be 135.4 per 100,000 among males and 43.0 per 100,000 among females (world standard). Truncated standardised incidence rates (ages 35-64 years only) were 334.2 and 104.3 per 100,000 for males and females respectively. Secondly we aimed to assess the feasibility of secondary prevention by early clinical diagnosis. However, the symptoms and signs observed were typically non-specific and associated with advanced disease in patients with cholangiocarcinoma who presented to hospital. Primary preventive measures appear to be the key to decreasing the mortality from this disease.

Q:

JDBC exception at getting decimal out parameter of stored procedure

I'm trying to get parameter from MYSQL procedure.
My proc:
CREATE PROCEDURE proc(someIn INT UNSIGNED,
                      anotherIn INT UNSIGNED,
                      OUT x DECIMAL(10,7),
                      OUT y DECIMAL(10,7))

My java code:
CallableStatement cs = conn.prepareCall("{call proc(?, ?,?,?)}");
cs.setLong(1, someLong);
cs.setLong(2, anotherLong);
cs.registerOutParameter(3,Types.DECIMAL,7);
cs.registerOutParameter(4,Types.DECIMAL,7);
rs = cs.executeQuery();
if (rs.next()) {
    double x = rs.getBigDecimal(3).doubleValue();
    double y = rs.getBigDecimal(4).doubleValue();
}

And I encountered on error at calling rs.next():

java.sql.SQLException: ResultSet is from UPDATE. No Data.

If I call the procedure with the same parameters manually, I get the result data.
I tried to change decimal to double, but this has no effect.

A:

The correct way to call the procedure is this:
cs.execute();
double x = cs.getBigDecimal(3).doubleValue();
double y = cs.getBigDecimal(4).doubleValue();

Lesson: How to Use JDBC to Call Stored Procedures

Introduction:
JDBC (Java Database Connectivity) is a Java API that allows you to connect to a database and execute SQL statements. In this lesson, we will learn how to use JDBC to call stored procedures.

Prerequisites:
To follow this lesson, you need to have a basic understanding of Java programming and SQL. You should also have a working knowledge of JDBC.

Objectives:
By the end of this lesson, you will be able to:
- Understand the concept of stored procedures
- Use JDBC to call stored procedures
- Troubleshoot common errors when calling stored procedures

Section 1: Introduction to Stored Procedures

Topic 1: What are Stored Procedures?
Stored procedures are pre-compiled SQL statements that are stored in the database. They are used to perform complex operations that would otherwise require multiple SQL statements.

Topic 2: Why Use Stored Procedures?
Stored procedures provide several benefits, including:
- Improved performance: Stored procedures can be optimized for better performance than ad-hoc SQL statements.
- Code reuse: Stored procedures can be reused across multiple applications, reducing code duplication.
- Security: Stored procedures can be used to restrict access to sensitive data by only allowing authorized users to execute them.

Section 2: Setting Up the Environment

Topic 1: Installing JDBC Driver
Before you can use JDBC to connect to a database, you need to install the JDBC driver for the database you want to use. The JDBC driver is a software component that allows Java to communicate with the database.

Topic 2: Creating a Connection URL
A connection URL is a string that contains information about the database you want to connect to, such as the host name, port number, and username. Here's an example of a connection URL for MySQL:

jdbc:mysql://localhost:3306/mydatabase

Section 3: Calling Stored Procedures

Topic 1: Preparing the Statement
To call a stored procedure, you first need to prepare the statement using the `prepareCall()` method. Here's an example:

CallableStatement cs = conn.prepareCall("{call my_stored_procedure(?, ?)}");

Topic 2: Setting Parameters
Once you have prepared the statement, you can set the parameters using the `setX()` methods. For example, if your stored procedure takes two integer parameters, you would do:

cs.setInt(1, param1);
cs.setInt(2, param2);

Topic 3: Executing the Statement
After setting the parameters, you can execute the statement using the `execute()` method.

cs.execute();

Section 4: Troubleshooting Common Errors

Topic 1: ResultSet is from UPDATE or DELETE
This error occurs when you try to call a stored procedure that returns a result set, but the procedure does not actually return any data. To fix this error, you need to either change the procedure to return no data or call it in a way that does not expect a result set.

Conclusion:
In this lesson, we learned about stored procedures and how to use JDBC to call them. We covered setting up the environment, preparing the statement, setting parameters, executing the statement, and troubleshooting common errors. By following these steps, you can easily call stored procedures in your Java applications.
