Hi All,

I didn't face this situation.
But I would like to know is there any way/method to get the DDL for the dropped table without using any tool on DB2 on z O/S.

Thanks in advance.

take the dump is a bit generic...
You will find/recover the data You have lost only and only by restoring everything

It might be possible to restore part of the catalog in catalog-lookalikes or unload from catalog imagecopies in sequential files.
and based on the info there retrieve the information to (manually) generate the DDL.
But this is not something you would accomplish in 30minutes.

thus my first answer => F*cked

if there was a dclgen run on the table
to create a copybook to used as an include member for host variables,
you can start there.

but, you will not have any index info, restrainsts, triggers,
in short you will only have the ddl to describe the columns.

Hello and welcome to the forum,

We do have some grumpy old men around here - i too am one icon_smile.gif

As you have seen, sometimes we get more involved with how the question was asked rather than the question itself. Unfortunate. However, if this helps teach people how to become better are getting informatoin, it is probably worth a few scrapes and bruises . . .

If one pay attention to the lessons, it gets better rather quickly.

As to your question - yes it has been answered and no, you cannot do this. How might you "read" something that no longer exists?

Well-managed organizations retain a repository of all of the database definitions that have been placed in use. Even if it is no more than copies downloaded for safekeeping. Once created, there is no good reason to lose anything that is part of the system. If you find yourself working in an environment that there is not proper backups of all of the source, jcl, copybooks, database definitions, etc., strongly encourage that these be put in place.

db2sysdba.zos,

Since you are just looking for the structure, can't you find it in Development/UAT/Model/Acceptance/(whatever that is below production).

Regards,
Sushanth

Recover the DB2 catalog? Not recommended as it might be a bit disruptive to other users. icon_evil.gif

Check your source libraries for an old DCLGEN that corresponds with the table. That might be enough to get you started.

Otherwise, as others have pointed out, you are SOL.

IMO production DDL should be under the control of a source management system.
