Re: Escaping Apostrophe

[haukex]

My first suggestion is to not re-invent the wheel, see for example SQL::Abstract (Update: example).

Also, you should always use placeholders wherever possible - see Bobby Tables!

DBI provides quote and quote_identifier, but I'd consider those a last resort if the above is not applicable for whatever unlikely reason.

Not trying to reinvent the wheel. But this is the code we have in just one of many places, using abstract or anything else will require a lot of changes through the code. All I need is a quick and dirty solution with what I have.

Quick, dirty — and, per other replies, kinda crazy (and also untested):

my ($row_sub_i_esc_sq = $row[$idx]) =~ s{ ' }{\\}xmsg;
$updstmt .= $hdr[$idx]." =  '". $row_sub_i_esc_sq ."' \r\n";

And BTW: It looks like you're dealing with single-quote characters, not apostrophes.

Update: Oops... Meant to write  s{ (?= ') }{\\}xmsg; and the substitute-on-assignment expression is also wrong, so finally (I think):

(my $row_sub_i_esc_sq = $row[$idx]) =~ s{ (?= ') }{\\}xmsg;
$updstmt .= $hdr[$idx]." =  '". $row_sub_i_esc_sq ."' \r\n";

Thanks choroba. Of course, that's what always happens when I post untested stuff.
