'SQL0902 An unexpected exception has occurred in Process: 4548' (74613)

User ran 'select * from syscat.tables' from Toad for DB2 and got error: IBM.Data.DB2.DB2Exception: ERROR [58005] [IBM][DB2.NET] SQL0902 An unexpected exception has occurred in Process: 4548 Thread 7 AppDomain: Name:Toad.exe

The problem has been tracked down to NICKNAME records (TYPE N) in SYSCAT.TABLES. When the system is a FEDERATED system and there are nicknames, DB2 adds TYPE N records into SYSCAT.TABLES with TIMESTAMP values of all zeroes.

STATUS

Waiting for a fix with ST 85987 on a future release of Toad for DB2.

WORKAROUND:

SELECT * FROM SYSCAT.TABLES WHERE TYPE <> 'N'
