I've actually used:

$sql = '... WHERE 1=1';
$sql .= ' AND ...' if (...);
$sql .= ' AND ...' if (...);
$sql .= ' AND ...' if (...);

In defense, 1) it wasn't in Perl, which has the convenient join function, and 2) the conditions where not already in an array as in the above snippet.

For the following, though, I deserve to be shot:

if (0
   || ...
   || ...
   || ...
) {
  ...
}

I do it just so all the conditions line up nicely.

Update: That should be WHERE 1=1 (not WHERE 1) because 1 does not mean true in SQL, or at least not for the database I was using.
