如何将特定存储过程的执行授予用户

Question

I have created some stored procedure on a specific schema.

In this stored procedure, I want to grant execute privilege.

So I wrote that :

GRANT EXECUTE ON PROCEDURE schema_name.proc_name TO 'user_name';
GRANT SELECT ON mysql.proc to 'user_name';

The problem is : My user can see every stored procedure. I wish he could only see the procedure where he has the EXECUTE privilege.

Is there a way to achieve that ?

Thanks in advance.

Answer 1

Yes... this works as expected if you don't grant the user the SELECT privilege on the mysql.proc table, either directly or indirectly, such as with GRANT SELECT ON *.* TO ...

Without SELECT permission on this table, a user can only see the existence of stored procedures and stored functions where they have other permissions, like EXECUTE .

Under the hood, the lack of SELECT on mysql.proc also prevents the user from seeing the procedures they don't have access to via the information_schema.routines pseudo-table.

You shouldn't need to GRANT SELECT ON mysql.proc to enable the user to execute procedures or functions... and if you do, then that seems like the question.

Answer 2

Problem solved.

In fact, To be able to execute stored procedure within MySQLForExcel, we need to SET the DEFINER of each stored procedure that we want to be called by a MySQLForExcel user.

DELIMITER $$

DROP PROCEDURE IF EXISTS `procedure_name` $$
CREATE DEFINER=`user_mysqlforexcel` PROCEDURE `procedure_name`(param)
BEGIN
     Do smth as usual
END $$

I found that here

Thank for the help.
