Question

I have a grant alter sequence to a user. But I have to specify the schema name to alter the sequence otherwise it comes back with error sequence does not exist. Is it possible to do the grant in a way so I don’t have to specify the schema name? I can do select/insert/update without specifying the schema name.

Answer 1

Name resolution and access privileges are separate concepts. The grant gives you permission to alter the schema, but you’re still constrained by the namespace you’re in. There are four ways to make a name in one schema resolve in another:

1. Reference the schema with the object name:
   select schema_name.sequence_name.nextval from dual;
2. Alter the current session to resolve names as if you were in the other schema:
   alter session set current_schema = schema_name;
3. Create a synonym for the object in the current schema:
   create synonym sequence_name for schema_name.sequence_name;
4. Create a public synonym for the object:
   create public synonym sequence_name for schema_name.sequence_name;
