Hi all,

Is there a way, tool, routine or such to change a table schema to a new schema? In the mainframe, we have if we want to change OLDNAME to NEWNAME we can code the following CATMAINT job:

CATMAINT UPDATE
SCHEMA SWITCH(OLDNAME, NEWNAME)

Is there any such utility for DB2 LUW?

you can duplicate a schema but you can't rename it

...change a table schema to a new schema?

AFAIK, the CATMAINT UPDATE SCHEMA SWITCH() renames a schema. Are you wanting to rename the schema that contains a table? Or are you wanting to change which schema a table is part of?

Hi!

There is a command in LUW called db2move see the manual
http://publib.boulder.ibm.com/infocenter/db2luw/v9/index.jsp?topic=%2Fcom.ibm.db2.luw.admin.dm.doc%2Fdoc%2Fr0024482.html

I think this is the only option in LUW that I know of that does this.

Hi!

Sorry db2move is used across databases. The procedure you are looking for is ADMIN_COPY_SCHEMA which does this within the db.

Tomas Helgi,

You got it right on the money! That ADMIN_COPY_SCHEMA is what I was looking for. And yes, does it with the same DB.

Thanks, Tom
