Обсуждение: Error code handling in perl

Hi all,

I am populating a table in postgres, writing the script in perl (using DBI),
and I am trying to do some error handling.  For example - this should return
an error due to unique violation:
>$sth=$conn->prepare("INSERT INTO tablename (names) values ($name)") or die
"error1 is: ".$sth->err;

>$sth->execute() or do{
>  print "state is: ".$sth->state."\n";
>  print "err is: ".$sth->err."\n";
>};

I always get the same SQLSTATE and ERROR, no matter what the error is:

>state is: S1000
>err is: 7

although in the documentation it says that the error code is "23505" (unique
violation).
Is there no way to identify the error by code from postgres via perl?

Thanks,
Elinor

Currently, DBD::Pg does not support the $sth->state method, but
it is high on the todo list and should appear in the next
version.
