ORA-01427 when upgrading from 11gR1 to 11gR2 using catupgrd.sql
Upgrading from 11gR1 to 11gR2 using catupgrd.sql failed because computer was accidentally shut.
When i try to re-run the catupgrd.sql i get ORA-01427
ERROR at line 6:
ORA-01427: single-row subquery returns more than one row
Why can this be happening?
