Thank you for the reply

How exactly would I do it? Lets say I have a value of

while(@values = $sth->fetchrow_array) {
   print "$values[8]\n";
}

the return value of that is : /vol/enycmmcfl01b_ssd2_home_1b_a/CBirbigl$'s as you can see if I try and take that value and insert in to an insert statement to execute that through perl

my $insert = "insert into dbtable (vol) values ('$values[8]')";

the insert statement will now fail because it will look like

insert into dbtable (vol) valuse ('/vol/enycmmcfl01b_ssd2_home_1b_a/CB
+irbigl$'s')

And well that wont work

Typically it would look a little like this.

my $insert = "insert into table (vol) values (?)";
$dbh->do($insert, $values[8]);

Generally, the notion is that you never directly put variables into SQL statements.

mrras25:

That's why davido mentioned placeholders. It's something like:

# Prepare a statement...
my $sth = $dbh->prepare("insert into dbtable (vol) values (?)");
my $funky_string = "/vol/enycmmcfl01b_ssd2_home_1b_a/CBirbigl$'s";
$sth->execute($funky_string);

This way, you don't have to worry about the odd characters inside your statement. Building your own statements like you were trying to do just leads to the difficulties you're experiencing. That's why placeholders were invented.
