e281. Calling a Stored Procedure in a Database

This example demonstrates how to call stored procedures with IN, OUT, and IN/OUT parameters.
    CallableStatement cs;
    try {
      // Call a procedure with no parameters
        cs = connection.prepareCall("{call myproc}");
        cs.execute();
    
      // Call a procedure with one IN parameter
        cs = connection.prepareCall("{call myprocin(?)}");
    
        // Set the value for the IN parameter
        cs.setString(1, "a string");
    
        // Execute the stored procedure
        cs.execute();
    
      // Call a procedure with one OUT parameter
        cs = connection.prepareCall("{call myprocout(?)}");
    
        // Register the type of the OUT parameter
        cs.registerOutParameter(1, Types.VARCHAR);
    
        // Execute the stored procedure and retrieve the OUT value
        cs.execute();
        String outParam = cs.getString(1);     // OUT parameter
    
      // Call a procedure with one IN/OUT parameter
        cs = connection.prepareCall("{call myprocinout(?)}");
    
        // Register the type of the IN/OUT parameter
        cs.registerOutParameter(1, Types.VARCHAR);
    
        // Set the value for the IN/OUT parameter
        cs.setString(1, "a string");
    
        // Execute the stored procedure and retrieve the IN/OUT value
        cs.execute();
        outParam = cs.getString(1);            // OUT parameter
    } catch (SQLException e) {
    }
