How do I change this:

mysql_query("ALTER TABLE samples ADD Nov_03 TEXT");

so that the column it sets up is not null?

Thanks,

Chris

Thank you, that works :)

So does it always have to be set up (ADD) and then changed (CHANGE) to make it not null?  It's not something that you can indicate in the ADD statment?

no you can do that with add
ALTER TABLE sample ADD Nov_03 TEXT NOT NULL.

but since the field Nov_03 already exist you just needed to change it.
