You cannot view the DDL per se, as it is not kept. However, the information contained in the DDL is maintained in the catalog tables; e.g., to get information about the columns of a table, select from SYSIBM.SYSTABLES.

All place I have worked keep their DDL in an application PDS so ask someone in that applications support/development team.
The problem I have is that people can explain things quickly but I can only comprehend slowly.

Hi Nic!
Yes, storing the DDL in a PDS so you can Library Manage it is a damned good idea?
Anyhow, (and as a confirmed true-blue biggot I hate to say this but…)...
If you have Platinum’s “RC/Query†installed (it's within CA Database Management Solutions for DB2 for z/OSâ€), as I do on the Customer’s site that I am using at the moment, then you can get the DDL out using command “DDL†against a TABLE (or an INDEX or TABLESPACE).
And this might look like this…
I don’t know if any of the IBM Tools do this – thinking FileManager for DB2? :/
On the other hand one could do it by-hand and execute a DESCRIBE on a table and get a lot of the info that way?
(this is from memory so do an RTFM first?
)…
In REXX…

Sorry for the late response..
Thanks all, for the valuable comments..
As steve said i used CA-DB2 tools to retrive the DDL information...On the other hand i used DCLGEN generator using DB2I..Both works fine..
