Subject [jira] Commented: (CAY-1354) Wrong Types mapping for selected values in Row Queries
Date Wed, 06 Jan 2010 04:41:54 GMT

    [ https://issues.apache.org/jira/browse/CAY-1354?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12796984#action_12796984

Evgeny Ryabitskiy commented on CAY-1354:
----------------------------------------

after some code inspection I found out that the problem is in JDBC drivers, we are using metaData.getColumnClassName(position);
that can return driver specific JAVA type (how it was with Oracle).

My idea is to use Cayenne TypeMapping for it. So I changed few lines and wow... we can delete
all that Oracle stuff from my last commits :)))
It is funny.....

One thing is that we should document (I mean user documentation) this type mapping.

>  By default every SQL type is mapped to some Java type by modeler.
> I am expecting same behavior in common DataRow queries (without ORM).
> But in fact half of types are not mapped correctly....
> Attached JUnit test can to explain problem with more details...
