[ http://nagoya.apache.org/jira/browse/DERBY-7?page=comments#action_56962 ] Amit Handa commented on DERBY-7: --------------------------------
It returns for nullif(1,2) --> returns 1 nullif(cast(null as int),2) --> returns 0 Also it returns an int and not as a char. I took nullif() as one column of select statement and it ResultSetMetaData returns java.sql.Types.INTEGER. Further Oracle works in same way. > 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.
