[ http://nagoya.apache.org/jira/browse/DERBY-7?page=comments#action_57076 ] Satheesh Bandaram commented on DERBY-7: ---------------------------------------
There was a related bug that Derby tried to address before going OPEN SOURCE. ij> values (case when 1.0=1.0 then null else 10 end); ERROR 42X89: Types 'CHAR' and 'INTEGER' are not type compatible. (Neither type i s assignable to the other type.) The above statement should have returned NULL instead. Don't remember who worked on that bug, but I might have mistaken this NULLIF issue with that one. I think issues here may be slightly different... > Bug in NULLIF Function > ---------------------- > > Key: DERBY-7 > URL: http://nagoya.apache.org/jira/browse/DERBY-7 > Project: Derby > Type: Bug > Components: SQL > Versions: 10.0.2.0 > Reporter: Tulika Agrawal > Priority: Minor > > Reporting for Christian d'Heureuse, filed on derby-dev list. > The NULLIF built-in function of Cloudscape 10.0.1.0 beta seems to accept > only string values. > Examples: > values nullif('a','b'); > --> OK > values nullif(1,2); > --> Error message: "ERROR 42X89: Types 'CHAR' and > 'INTEGER' are not type compatible.
