We have 2 schemas in our DB and I am trying to access the external table row count in schema A from schema B.
The external table has a grant GRANT SELECT ON A.LETTER TO B WITH GRANT OPTION;
When I call: SELECT COUNT(*) FROM A.LETTER; from Schema B I always get ORA-06564: object A does not exist
This is the same grant we have on regular tables and we are able to get counts from these tables. I'm not sure what the problem is here or how best to fix it?
