Allow for LONG VARCHAR to be compared to LONG VARCHAR -----------------------------------------------------
Key: DERBY-5130 URL: https://issues.apache.org/jira/browse/DERBY-5130 Project: Derby Issue Type: Improvement Components: SQL Affects Versions: 10.7.1.1 Reporter: Lukas Eder Priority: Minor Interestingly, this is not possible: select 1 from SYSIBM.SYSDUMMY1 where cast('2' as long varchar) = cast('2' as long varchar) Whereas these statements are executable: select 1 from SYSIBM.SYSDUMMY1 where '2' = '2' select 1 from SYSIBM.SYSDUMMY1 where cast(cast('2' as long varchar) as varchar(1)) = cast(cast('2' as long varchar) as varchar(1)) According to the documentation that is the correct behaviour: http://db.apache.org/derby/docs/10.7/ref/rrefsqlj58560.html Nevertheless, if casting is possible between LONG VARCHAR and VARCHAR, and assignment too, then I don't understand why LONG VARCHAR cannot even be compared to LONG VARCHAR Note: A similar issue has been open for a long time: https://issues.apache.org/jira/browse/DERBY-342 -- This message is automatically generated by JIRA.
