Oops...I missed this last part. If you don't want to have to do the quoting
yourself, use the quote() method and make any empty strings undef instead
NULL.
$database = connect();
$name = $database->quote($var);
$database->do("insert into employees(name) values $var");
if $var is undef, it inserts null, if not it properly quotes the string,
including escaping any nasty characters it might include like the
apostrophe.
In the future, you might want to post questions like this to the dbi-users
list; you are more likely to get help there. Also, you may want to take a
look at the book "Programming the Perl DBI," or, if you are more harcore,
try the command "perldoc DBI." This stuff is pretty well documented in
both those resources.
