in thread How to give a database as an input in a perl script?

Generic version:
use strict; use warnings; use DBI; my $dbh = DBI->connect(...); my @tables = $dbh->tables(undef, undef, undef, 'TABLE'); print "$_\n" for @tables;
The tables method should work for all databases supported by DBI. Sending a show tables query is MySQL-specific - I know it doesn't work with SQLite databases and, from long-gone memory, I'm pretty sure PostgreSQL wouldn't like it either. Any other database engine, I can only say "seems unlikely".

[LanX]: my main problem will be to cnvince my colleagues that our productive code is broken oO ... so in the end I will just make a workaround :-/

[Corion]: LanX: Yes, that's the main problem - you have lots (and lots) of workarounds in various places and stages of the processing, and to clean that mess up requires action across the complete codebase. And it's almost impossible to do it piece-by-piece
