Re: [PHP-DB] my sql text query
Nope, you change the field to not null then it won't allow null values in the database. Since the data already has null values, the Alter Table would probably fail. I should have been clearer - change the text field to non-null - this will cause the null entries to become empty strings (and hence your mysql_fetch_array calls will have an entry for that field containing an entry string) and then back again to null. I've just tried it on my machine and it works a treat.

[PHP-DB] my sql text query
hi, i'm currently writing an e-commerse site using php for the shopping cart stuff and mysql as the db. i've got a text filed of type text that holds descriptions for the items but only need to display it if a description exists, so many of the fields are null. the field was added to the table when the table was already populated and when try to read it i get errors saying the index is not defined ... if i change it to varchar(255) there is no problem ? can anyone help ?

I'm still trying to figure out what any of this has to do with an index? Do you have an index on this description field?
