Hello!

I'm accessing to an Oracle DB using perl's DBI. Like this:

$sth = $dbh->prepare("update...");
$sth->execute($nw,$start,$ende,$old );
$rv = $sth->rows;

If I give the table name and column names in the prepare line
incorrectly (eg: I want to update a row that isn't exists) I get

DBD::Oracle::st execute failed: ORA-00904: "UCRPA": invalid identifier error message.
How can I define my own error message in this case, like:
die (" Can't update because invalid entry was defined");

I tried using eval and HandleError, but these didn't work for me.
Thanks
