Kim Haase reassigned DERBY-5557: -------------------------------- Assignee: Kim Haase > NULLIF topic in reference manual should explain NULLIF > ------------------------------------------------------ > > Key: DERBY-5557 > URL: https://issues.apache.org/jira/browse/DERBY-5557 > Project: Derby > Issue Type: Improvement > Components: Documentation > Affects Versions: 10.8.2.2 > Reporter: Knut Anders Hatlen > Assignee: Kim Haase > > The section describing NULLIF in the reference manual is a bit cryptic. > http://db.apache.org/derby/docs/10.8/ref/rrefcasenullif.html > It says that NULLIF is used for conditional expressions, and that it is > similar to CASE, but it doesn't say in plain words how it works. It would be > good if it could mention that NULLIF returns NULL if the two arguments are > equal, and that it returns the first argument if they are not equal. -- This message is automatically generated by JIRA.
