I gather that you are not using parameterized sql statements
for doing the table updates, and you should be. You haven't
provided enough code for anyone here to give a detailed reply
about what needs to be done, but assuming that you are using
the DBI module to perform the updates, then check out the
part of the DBI man page that describes the functions
"prepare", "bind_param" and "execute(@bind_values)".
In a nutshell, you start with an update statement like
my $sth = $dbh->prepare("update my_table set title=? where key=?");
and then execute the statement with a list of scalar values
like this:
$sth->execute( $in{title}, $in{key} );
No quotation marks are needed around the string values being
handed to the database, and there is no need to escape things
within the scalar values that happen to be quote characters.
