Granting Create Access [message #656150]

Hi,
We have requirement where from GUI user will send details of table and we need to create and alter tables which starts from ZZ_*( Eg: ZZ_emp) in another schema.
Along with create table, user should be able to create index and create referential integrity constraint only for ZZ_* tables.

Also We don't want to provide create any table access to user as user should be able to create or alter tables which starts ONLY from ZZ_* and not other tables in another schema.

Could anyone please help in solving the above requirement.

Regards,
Lokesh

IMO, whole "design" is daft & violates Third Normal form by duplicating data purposefully.

It can be done, but I refuse to be complicit is aiding & abetting wrong design principals.

Not everything that can be done, should ever be actually done.
You can also poke yourself in the eye with a sharp pencil.
I strongly advise against doing either.

Hi,
we need to create and alter tables . . . in another schema.

Also We don't want to provide create any table access

Inherently contradictory requirements.

The only way that user A can create a table in schema B is with the CREATE ANY TABLE privilege.

Even that aside, I agree with BlackSwan. The overall requirement a disaster in the making.

Create a procedure that can do it after validating all parameters including caller and grant EXECUTE on it to other accounts.

What problem are you trying to solve? Saying that "you have requirement": who requires that, exactly? Why would users create tables? Why wouldn't they INSERT data into existing ones?

On the other hand, that sounds as if you are creating environment for students and want to apply certain restrictions. How about letting them do whatever they want in their own schema? Just don't give them unlimited quota on a tablespace.

Anyway: if you could explain the problem, someone might suggest a better approach than the one you mentioned.

Thank You all for providing inputs.

We are implementing the solution as suggested by Michel Cadot i.e to Create a procedure that can do it after validating all parameters including caller and grant EXECUTE on it to other accounts.

Thanks Michel.

Lokesh

It'd be great if you could post the code for mainly 2 reasons:
* It may help people with the same kind of problem
* We could improve it to your benefit
