Re: [Phpwebsite-developers] MySQL-NULL-Problem

[Steven L. <st...@tu...>]

Franz,

  Please do send in your patch, actually add it to the patch list on
sourceforge here
https://sourceforge.net/tracker/?func=add&group_id=15539&atid=315539

we typically do our sql queries in all caps so 'IS NULL' would be
appropriate.

ex. "SELECT * FROM my_table WHERE my_column IS NULL".
