Copying tables between schema owners

Question

In Timesten, can you copy tables across schemas/owners?
i.e. OWNER_A.TABLE_Y to OWNER_B.TABLE_Y
Where TABLE_Y has the same definition? Basically, I'd like to be able to backup one datastore and restore it in another datastore that has the same table definitions, but may have a different owner name.
Thanks,
Larry

I'm not completely clear on exactly what you are looking to do. On one hand you ask about copying tables between schemas. This is easily done:
CREATE TABLE OWNER_B.TABLE_Y AS SELECT * FROM OWNER_A.TABLE_Y;
This only works for TimesTen tables that are not part of a cache group; specifically the source table can be part of a cache group but the target table cannot. if the target table is part of a cache group then you need to:
1. Create the cache group containing the target (cached) table.
2. INSERT INTO OWNER_B.TABLE_Y SELECT * FROM OWNER_A.TABLE_Y;
But then you mention backup and restore. Since TimesTen backup/retore (ttBackup/ttRestore) works at a physical level you cannot rename/copy tables as part of that. You might be able to use ttMigrate with the -rename oldOwner:newOwner option but there are some constraints around this (one being that PL/SQL cannot be enabled in the database).
