Had you even bothered to super search using your node title you would have found No database driver specified and DBI_DSN env var not set, this may help, since you don't show us any of the code that is causing this problem, there is not much more to add, other than read How do I post a question effectively? and the PerlMonks FAQ if you have not already done so. Update:Slight update, added links to How do I post a question effectively? and PerlMonks FAQ Martin	[reply]

I have a hunch you have your dbi connect string in an array and you're passing it to DBI. I have to guess because you didn't provide any code (which would definitely help). Note that there's a difference between `$ar` and `@ar` below. `my @ar = (1..3); my $ar = \@ar; print "@ar \| $ar \n";` [download] Most likely you just have to do something like `DBI->connect(@$arguments)` to turn your arrayref into an array. -Paul	[reply] [d/l] [select]
