Can I do a mysql Select, Update and Delete in one query?

Question

Can I say that one of many ways to optimize mysql is to reduce the number of queries?

If that so, can I do this:

- Select \"data\" => $A from tabl         


        

Answer 1

Create a stored procedure:

DELIMITER // 

create procedure empproc(in name varchar(255),in fathername varchar(255),in password varchar(255))

begin

        Select * from xemp where uname = name and fname = fathername;

        insert into xemp values(name,fathername,password);

end //
delimiter ;

Java Code.....

import  java.sql.*;

public class StoredProcedure {

    public static void main(String a[])throws Exception {

        Class.forName("com.mysql.jdbc.Driver").newInstance();
        Connection conn=DriverManager.getConnection("jdbc:mysql://localhost:3306/01jim2010","root","");
        CallableStatement calstat=conn.prepareCall("{call empproc(?,?,?)}");
        calstat.setString(1,"Jimit");
        calstat.setString(2,"Temp");
        calstat.setString(3,"Temp");

        ResultSet rs = calstat.executeQuery();
        conn.close();
        calstat.close();

        System.out.println("Your data has been inserted into table.");
      }
}
