How is a stored procedure executed in JDBC?Question 3Answera.Using the executeProcedure methodb.Using executeQueryc.Using executeUpdated.Using CallableStatement

A stored procedure is executed in JDBC using CallableStatement. Here are the steps:

1. First, establish a connection to the database using the DriverManager.getConnection() method.

Connection con = DriverManager.getConnection(url, user, password);

2. Create a CallableStatement object. A CallableStatement object provides a way to call stored procedures in a standard way for all RDBMSs. The CallableStatement object contains a call to a stored procedure.

CallableStatement cstmt = con.prepareCall("{call MYPROCEDURE}");

3. Execute the stored procedure using the execute() method of the CallableStatement object.

cstmt.execute();

4. If the stored procedure returns a ResultSet, you can retrieve it in the same way as you would with a Statement object.

ResultSet rs = cstmt.getResultSet();

5. Finally, close the resources.

rs.close();
cstmt.close();
con.close();

Please note that "{call MYPROCEDURE}" is a placeholder for your actual stored procedure call. Replace "MYPROCEDURE" with the name of your stored procedure. Also, if your stored procedure takes parameters, you can set them using the setXXX() methods of the CallableStatement object. For example, if your stored procedure takes an integer as a parameter, you can set it using the setInt() method:

cstmt.setInt(1, 123);

In this case, "1" is the parameter index and "123" is the value you want to set.

A stored procedure is executed in JDBC using the CallableStatement. Here are the steps:

1. First, establish a connection to the database using the DriverManager.getConnection() method.

2. Once the connection is established, you can prepare a call to the stored procedure using the Connection.prepareCall() method. This method takes a string that holds the call to the stored procedure. The string should be in the following format: {call MY_PROCEDURE(?, ?)}. The question marks are placeholders for parameters.

3. If the stored procedure takes parameters, you can set them using the various CallableStatement.setXXX() methods. The first argument to these methods is the parameter's index (starting from 1), and the second argument is the value to set.

4. After setting all parameters, you can execute the stored procedure using the CallableStatement.execute() method. This method returns a boolean indicating whether the first result is a ResultSet.

5. If the stored procedure returns a result set, you can retrieve it using the CallableStatement.getResultSet() method. You can then process the result set as usual.

6. Finally, don't forget to close the CallableStatement and Connection objects to free up database resources. You can do this using the close() method of these objects.

A stored procedure is executed in JDBC using the CallableStatement. Here are the steps:

1. Load the JDBC driver: This is the first step in any JDBC process. You load the driver using Class.forName().

Class.forName("com.mysql.jdbc.Driver");

2. Establish a connection: Use DriverManager.getConnection() to establish a connection to the database.

Connection con = DriverManager.getConnection(url, user, password);

3. Create a CallableStatement: A CallableStatement object provides a way to call stored procedures using standard SQL syntax. It is created by calling Connection.prepareCall().

CallableStatement stmt = con.prepareCall("{call MY_PROCEDURE(?)}");

4. Set input parameters: If your stored procedure takes parameters, you can set them using one of the setter methods defined in CallableStatement, such as setInt(), setString(), etc.

stmt.setInt(1, 10);

5. Execute the stored procedure: Call CallableStatement.execute() to run the stored procedure.

stmt.execute();

6. Retrieve the result: If your stored procedure returns a ResultSet, you can retrieve it in the same way as you would with a Statement object.

ResultSet rs = stmt.getResultSet();

7. Close the connection: It's important to close the connection once you're done with it to free up resources.

con.close();

So, the correct answer to your question is d. Using CallableStatement.
