Hi guys,
Running into a frustrating problem. When I have a empty table in mysql database, i tried run a select statement in my perl script and supposing get a NULl return value. Is the NULL returned from mysql is described as string in perl or as undef in perl?.. As there is no the word NULL in perl
Thank you very much guys
NULL values are represented as under if you're using the Perl DBI interface.
However, an empty table will return an empty result set, which is different than undef. If you're really getting undef back, there may be an error in your query. --------------------------------------------------------------------- Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
