[ http://nagoya.apache.org/jira/browse/DERBY-7?page=comments#action_57077 ] Christian d'Heureuse commented on DERBY-7: ------------------------------------------
I think this is the same problem, because NULLIF() and CASE (whenThenExpression) both are implemented using CONDITIONAL_NODE. But for CASE, the error can be avoided by using "CAST(NULL as INT)" instead of an untyped NULL: values (case when 1.0=1.0 then cast(null as int) else 10 end); For NULLIF() this is not possible. > 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.
