As others have noted, ? is the character for place holders in DBI. I recommend reading about them and using them, they make life much better and a far more efficient, especially if you use $dbi->prepare_cached, which won't recompile your sql statement every time.
You should change your function to look like this:
sub Do_SQL {
my $dbh = shift; # unless you are using a bad global
my $statement = shift;
my @values = shift;
# don't check for errors here as chances are
# no runtime errors will occur once you are done
# debuging your code
my $sth = $dbh->prepare_cached($statement);
# interopolates your placeholders
$sth->execute(@values)
or error_function($dbh->errstr); # you can do
# the print here
}
So, with this you could do database work with:
Do_SQL(
$dbh,
'INSERT INTO some_tbl (some_text) VALUES(?)',
'Hello?'
);
Keep in mind that this is very limiting; you can't check the return values of your statements to find out the number of rows affected and so forth.
cheers.
