There is only one permission that may be granted on a procedure – the EXECUTE permission to execute (or CALL) the procedure.
Permission to execute stored procedures may be granted by the DBA or PERMS ADMIN or by the owner of the procedure (the user ID that created the procedure).
Use the GRANT EXECUTE statement to grant permissions on procedures. For example, to grant M_Haneef permission to execute a procedure named my_procedure:
Procedures execute with the permissions of their owner. Any procedure that updates information on a table will execute successfully only if the owner of the procedure has UPDATE permissions on the table.
As long as the procedure owner does have the proper permissions, the procedure will execute successfully when called by any user assigned permission to execute it, whether or not they have permissions on the underlying table. You can use procedures to allow users to carry out well-defined activities on a table, without having any general permissions on the table.
