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.
