mysql dynamic query in stored procedure

Question

i am creating a dynamic query in stored procedure. my stored procedure is as follows:

CREATE PROCEDURE `test1`(IN tab_name VARCHAR(40),IN w_team VARCHAR(40))         


        

Answer 1

You missed the quotes in WHERE clause.

Try like this:

SET @t1 =CONCAT("SELECT * FROM ",tab_name," where team='",w_team,"'");

Explanation:

Query from your code would be like:

SELECT * FROM Test where team=SPA

And we changed it to:

SELECT * FROM Test where team='SPA'
