Passing column name as a parameter in mysql stored function

Question

I am using a MySQL stored function where I have created a function and I have passed column name as a parameter to this function. Suppose

CREATE DEFINER=`ro         


        

Answer 1

After a long search I found that a stored function can be used only to return a single value or a calculated answer (Arithmetic). For your query just use a stored procedure. It is as simple as creating a query from the front end. And here is the syntax:

Use CONCAT(X1,X2,X3 . . .) to do it as you would like.

CREATE DEFINER=`root`@`localhost` PROCEDURE `Test`(table longtext,column longtext,e_id longtext)

SET @s=CONCAT('Select ',table,' from ', column, 'Where employee = ',e_id);

PREPARE stmt1 FROM @s;

EXECUTE stmt1;

DEALLOCATE PREPARE stmt1;

END
