Обсуждение: Can trigger procedures return value

Hi all,
 Can trigger procedures can return
 values.

 Actually I need a trigger that should
 not allow rows to be updated in a particular
 table on a specific condition.(like users
 other than 'manager' should not be allowed to
 update that table')

 If the user other than 'manager' tries to update
 that table, I need a error number that should be
 returned by trigger procedure to prompt the
 user that he/she is not a valid user.

 If it is not possible to return error from
 trigger procedure, what could be the possible
 way to solve the above problem.

regards,
Deepa. K

What you want is 'raise exception', which allows you to return an
error message explaining things.

Use something like "RAISE EXCEPTION ''You are not authorized to
update this information'';"
