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? :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/OS”), 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).
RQTL   R14    --------------- RC/Q Table List --------------- 06-02-11   10:28
COMMAND ===>                                                  SCROLL ===> PAGE
                                                                               
 DB2 Object ===> T                       Option  ===> L    Where => N         
 Table Name ===> SAMPTABL             >  Creator ===> *                     > 
  Qualifier ===> *                    >  Grantor ===> *                     >

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? :geek: )…
In REXX…
. . .
PARSE VALUE 0 WITH . col. 1 col.0 typ. 1 typ.0 . sqlda.
table = 'SAMPTABL'
ADDRESS DSNREXX "EXECSQL DESCRIBE TABLE :TABLE INTO :SQLDA"
DO i = 1 TO sqlda.sqld                                   
   col.i = sqlda.i.sqlname                                 
   typ.i = sqlda.i.sqltype                                 
END
PARSE VALUE i-1 WITH col.0 1 typ.0

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..
