But with UPDATE you have the %Fields option so it should not present a problem.

Subject: Re: Handling default fields on RPG WRITE

Funnily enough I was just looking at some of this stuff.

The RPG has no influence on the identity column.
You can clear the record format and the ID column will not be affected.

As far as defaults set up in the DDL,
I'm not aware of how you can be influenced by them in RPG.

My experience is that RPG will set up storage for all of the fields on the file and initialise them to the default values for the data types, without reference to how the table was defined in DDL.
In any case most people would Clear a record format before building it for an RPG write I would have thought.

You cannot specify %Fields on the WRITE, like you can on UPDATE.

There is also a it of a catch with things like Dates where I believe SQL inserts would default to the current date but RPG would default to *Loval ( well, it does for the *ISO dates I tested it with )
