Re: DDL question

Depending on how often you need to do this, id it is a once off, iNav would
work generate the SQL code, removing the NOT NULL and running the script to
rebuild the table. This is the simplest way. The more complicated way is to
look at the DDL in iNav and do a change on each line and remove the NOT
NULL.

If you have multiple tables to do, I would suggest a simple RPG program
receiving parms of the table and library names. Then loop through
QSYS2.SYSCOLUMNS picking up each column in the table and generating a
dynamic instruction to do a ALTER TABLE to remove the NOT NULL.

Nathan,

Is there a way to remove the NOT NULL from all columns with one command,
or do I need to remove NOT NULL from each column individually?

In regard to utilities that generate DDL source from existing physical and
logical files, Justin just mentioned the one in iNav. Years ago I
downloaded a copy of GENDDL from Tommy Holden.

These utilities just generate DDL source. GENDDL outputs it to a source
member that you specify on the command. You just mass replace "NOT NULL"
with "" using an editor (i.e. SEU), then RUNSQLSTMT to create the table.
