Question

This works:

(connect to some_db)
INSERT INTO some_schema.some_table(id) VALUES (some_schema.some_table.nextval);

THis works too:

(connect to some_other_db)
SELECT some_schema.some_table.nextval@some_db FROM DUAL;

This does not work:

(connect to some_other_db)
INSERT INTO some_schema.some_table@some_db(id) VALUES (some_schema.some_table.nextval@some_db);

The error I get is ORA-01031: insufficient privileges ORA-02063: preceding line from SOME_DB. The insert privilege for some_schema.some_table is granted through a default role.

What could be the problem here?

Update: adding select right for the table made the remote query work.

Answer 1

If you insert in the local database the insert privilege is sufficient, if you insert into the remote database, you need select and the inset privilege as it will do a select during the parse phase.
