[teiid-issues] [JBoss JIRA] (TEIID-5295) Comparisons of timestamps don't work correctly for MongoDB

    [ https://issues.jboss.org/browse/TEIID-5295?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13552446#comment-13552446 ] 

Steven Hawkins commented on TEIID-5295:
---------------------------------------

[~jmartisk] Are you modeling the time type directly, or do you have a view layer converting to time?  MongoDB does not directly support a time type, so the behavior will likely not be as expected unless using a view.

> Examples of queries which don't behave as expected when running against MongoDB:
> {noformat}
> SELECT BQT1.SmallA.TimeValue FROM BQT1.SmallA WHERE BQT1.SmallA.TimeValue > '17:00:00'
> {noformat}
> returns ALL timevalues which are not null
> {noformat}
> SELECT BQT1.SmallA.TimeValue FROM BQT1.SmallA WHERE BQT1.SmallA.TimeValue < '17:00:00'
> {noformat}
> returns NO timevalues even though there are some less than 17:00
> {noformat}
> SELECT BQT1.SmallA.TimeValue FROM BQT1.SmallA WHERE BQT1.SmallA.TimeValue = '15:00:00'
> {noformat}
> returns nothing
> {noformat}
> SELECT BQT1.SmallA.IntKey FROM BQT1.SmallA WHERE BQT1.SmallA.TimeValue IN (convert('05:00:00', time), convert('15:00:00', time))
> {noformat}
> returns nothing
