[teiid-issues] [JBoss JIRA] Commented: (TEIID-1341) boolean=true doesn't work predictably against MySQL connector

    [ https://jira.jboss.org/browse/TEIID-1341?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12561001#action_12561001 ] 

Steven Hawkins commented on TEIID-1341:
---------------------------------------

The conversion logic in teiid expressly handles non-0 values as true, but there is no special logic in comparison predicates to handle this case.

> MySQL defines false as zero and anything else as a true. So, in MySQL, writing "... where boolean_column = true ..." will usually not evaluate correctly because true is defined as one. To avoid this confusion, MMX should translate boolean_column=true to boolean_column<>false in the SqlTranslator of the MySQL Connector.
