Hi Matt,

The ALTER SESSION SET CURRENT_SCHEMA command is at last mentioned in = the
Oracle8i documentation set.
However, it only changes the default schema of reference, not the user identity,
and therefore cannot be used to perform grants on behalf of the schema owner.

What you can do however is to temporarily create a procedure in that = schema
which takes an arbitrary SQL statement as the argument and executes it = using
DBMS_SQL. You then just call that procedure with the grant statement as = the
argument, and it will be performed in a recursive session with the = identity
of
the schema owner.

This idea comes from http://www.oracledba.co.uk/tips/grants.htm.

Where is this documented? I'm trying to do grants after switching the current schema; it's not working.
