Re: DDL - Handling Nulls

FWiW: The ALTER TABLE to ALTER COLUMN to SET NOT NULL [and optionally SET DEFAULT] to change the current column attributes if there are no NULL values already in the column and none were\are intended.
http://publib.boulder.ibm.com/infocenter/iseries/v5r4/topic/sqlp/rbafychgcol.htm

Of course the same changes should be made to the original source for if\when it would be used again to CREATE TABLE; i.e. best to create as desired versus alter to become the desired.

I also know that I can code the DDL up front to not allow nulls and provide a default value, but is there a way to handle nulls in an RPG
IV program without having to recompile the DDL?

Just looking for as many options here as possible, knowing that the
best one is to code it right up front....
