Re: Re2: Sorting data pullled in by DBI

The problem with !$_ (and jeffa's map example), is that it tests for truth, so you also end up substituting any values that match 0 instead of only those that are undef.

Perhaps you meant to use !defined instead?

Yes, `!defined` is probably a better CONDITON for the original data... I was merely refactoring the given map code. However, since you probably want the empty string to be defaulted as well, I'd probably use something like: `$_ = ' ' for grep {!defined or $_ eq ''} @arr;` [download] -Blake	[reply] [d/l] [select]
