Dear All,

I have a function like 
sub sql_escape 
{
    my $text = shift;
    $text =~ s/'/\'/g;
    $text =~ s/"/\"/g;
    $text =~ s/\\/\\\\/g;
    return $text;
}

Outputs this: O'REILLY

When I print the result of that in a double quoted string, like so: my $escaped_text = sql_escape ($raw_text); print "$escaped_text" , it prints single quotes without the backslash.

But if I change the function to add another backslash, it starts printing 2 backslashes:

sub sql_escape 
{
    my $text = shift;
    $text =~ s/'/\\'/g;
    $text =~ s/"/\\"/g;
    $text =~ s/\\/\\\\/g;
    return $text;
}

Outputs this: O\\'REILLY

How can I change it to output only 1 backslash?
