Answer 1

Try this,you had mistake in "ganesh" and also in concat function , missing

DELIMITER $$
        begin
        declare var a int;
        set a="select biology from app.students where studname='ganesh'";
        select concat('the student name is', a);
        end$$

Just create the stored procedure in the MySql workbench exactly the same as you normally would. It doesn't matter that you are calling it from Java or anywhere else. Your stored procedure looks very messy and makes very little sense though, so I think you need to work on that!

Try just using the query analyzer and build the query not inside a stored procedure first.

Once the statement is written embed it in a stored procedure and then check you can still call it and it works from query analyzer.

Once the stored procedure is written you can just use a PreparedStatement to call it exactly the same as for any other SQL statement.
