Stored Procedure with Parameters using Jdbc

Callable statement consist of three parameters  we used the form with a result parameter, which means that we must set it as an OUT parameter.

To clarify I have numbered the parameters:

Authors is Stored procedure name it takes three parameters.i clearly explain below.

{call authors(?,?,?)}
                      1 2 3
                      In out

CREATE PROCEDURE authors (p_auth_id varchar(15), OUT p_auth_fname varchar(20), OUT p_auth_lname varchar(20))

Above example takes the first one in IN parameter, the second and third are OUT parameters and returns a result.

Therefore the correct way to call it is:

Create a CallableStatement object to call the store procedure.

 CallableStatement stat1 = con.prepareCall(“{call authors(?,?,?)}”);

CallableStatement stat1 = con.prepareCall("{call authors(?,?,?)}");
stat1.setString(1, "1");
stat1.registerOutParameter(2,Types.VARCHAR);
stat1.registerOutParameter(3,Types.VARCHAR);

Parameter 1 is an IN-only parameter the stored procedure doesn’t return any other value besides the OUT-parameters.

To read the result from the OUT-parameters we also have to adapt the parameter numbers:

System.out.println(stat1.getString(2));
System.out.println("   ");
System.out.println(stat1.getString(3));

i have attach the full Code below.

import java.sql.*;

public class JdbcFind {

	public static void main(String[] args)
	{
		    Connection con=null;
			try {
				Class.forName("com.mysql.jdbc.Driver");
				con = DriverManager.getConnection("jdbc:mysql://localhost/abclibrary", "root","");	
			        CallableStatement stat1 = con.prepareCall("{call authors(?,?,?)}");		
			        stat1.setString(1, "2");
			        stat1.registerOutParameter(2,Types.VARCHAR);
			        stat1.registerOutParameter(3,Types.VARCHAR);
				stat1.execute();
				System.out.println(stat1.getString(2));
				System.out.println("   ");
				System.out.println(stat1.getString(3));
				
				}
			    catch(ClassNotFoundException cle)
				{
				System.out.println("check your jdbc connection" );
				}
			     catch(SQLException sqe)
				{
				System.out.println("Check connection" +sqe);
				}
			     finally
			      {
				    try{
						if(con != null)
						con.close();
						}
				    catch(Exception e)
				    {
				    	e.printStackTrace();
				    }
					}
		}	
}
