Hi All,

Consider a schema (X) that has select any table privilege but we want to exclude 1 or more schemas (Y,Z) that should not be accessed by the schema X.
Can you please let me know if this is possible?

In our case MGR_FPA is schema X and as MGR_FPA has SELECT ANY TABLE privilege If I create any secure schema that will be accessible to MGR_FPA user.

I would like to create a schema that is more secure and tables in that schema should be only accessible to that user.

Other alternative is that I will have to remove select any table privilege from MGR_FPA, but that is a costly alternative as many programs may fail and need immediate attention.

Please let me know if there is a way to make it happen.

It is not possible.
SELECT ANY TABLE is ANY table.

So grant it explicit object privileges and not generic system one.
