Re: CRTDUPOBJ vs SQL CREATE TABLE LIKE

Jeff Crosby wrote:


CREATE TABLE workfile as (Select * from referencefile) WITH DATA

Which worked, and brought the data over, but still no joy.  The file level
ID is totally different.


Jeff:

One minor note for clarity and an added note 'just in case'...
Of course the file level IDs will be different. The file level IDs will be different (probably) every time you run it. This is because "file level ID" is a date/time-stamp of when the file was created.
This is just slightly different from a "member level ID", but way different from a "format level ID" which is an encoding of the characteristics of the format record buffer fields. (It's the buffer layout that your program code cares about -- which fields, of what types and lengths, and what order in the buffer. If a different file has the same buffer layout, then OVRDBF works without level-check.)
I'm pretty sure from your following comments in the thread that you meant "format level ID", but wanted to make sure the problem was clear for the archives. 

Now, _just in case this affects you_...
Please review Info APAR II14134 for V5R4 (which also has info for V5R3 at least) which discusses a bug related to SQL-created tables and their format level IDs. This can be seen at:

It doesn't seem directly related, but ya' never know. And if you don't have the PTFs, you should get them regardless. For V5R4 it's SI20165. For V5R3 it's SI20165. (Or their supersedes.) Recent DB2 Groups should have those.
