Question

Using PhpMyQdmin, how do I update ALL empty fields in a single column. I have tried a few commands I found online but none seem to do it.

Table is called “news” and column is called “profile_4” and type is “varchar(255)”

I tried this:

UPDATE news SET profile_4 = 'General' WHERE profile_4 = NULL 

but it didn’t work.

What I need is to update the empty column fields with ‘General’

Thanks
Chris

Try this :

UPDATE news SET profile_4 = 'General' WHERE profile_4 IS NULL OR profile_4 = ''

For full reference see http://dev.mysql.com/doc/refman/5.0/en/working-with-null.html

You cannot use arithmetic comparison operators such as =, <, or <> to
test for NULL.
