Subject [jira] Updated: (DERBY-4000) Reference manual leaves != out of list of boolean operators
Date Fri, 19 Feb 2010 20:16:27 GMT

     [ https://issues.apache.org/jira/browse/DERBY-4000?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Kim Haase updated DERBY-4000:
-----------------------------

    Attachment: rrefsqlj23075.html
                DERBY-4000.diff

This is low-hanging fruit -- I'm attaching DERBY-4000.diff and rrefsqlj23075.html (Boolean
expressions), with a note added to the table row on comparison operators. We don't have much
precedent for talking about nonstandard items, so I hope this language is acceptable.

I also added a missing space after a comma in the note on LIKE expressions.

> Table 1, SQL Boolean Operators, at <URL:http://db.apache.org/derby/docs/dev/ref/rrefsqlj23075.html>
lists the comparison operators <, =, >, <=, >=, <>. Derby also accepts !=,
which I believe has the same meaning as <>. The != operator should be documented along
with the other operators. (I haven't checked whether != is standard SQL.)
