in thread Throw DB error

I am sorry again i am disturbing YOU. i don't want to change either in sql query or deleting rows. I am asking that, is there any mechanism in perl that a person can throw error intentionally. Because i am using

$SIG{__WARN__} = \&WARN_Handler; $SIG{__DIE__} = \&DIE_Handler;

And i also written code for handle error using WARN_HANDLER AND DIE_HANDLER

      WARN_Handler and DIE_Handler are the two sub routines i have defined. Whenever db throw errors these routine will get activated. i am calling these methods using SIG { } command See bellow code

      $SIG{__WARN__} = \&WARN_Handler; $SIG{__DIE__} = \&DIE_Handler;

      here &WARN_Handler and &DIE_Handler are the two sub routines OK. So now tell me how to throw db error as we in JAVA or some languages.

        warn and die are perl sub routines OK, understand?
