Rick Hillegas updated DERBY-6036:
---------------------------------
Attachment: derby-6036-01-aa-testForRestrictionPushing.diff
Attaching derby-6036-01-aa-testForRestrictionPushing.diff. This adds a test
case to verify that restrictions are passed through the view but not
projections. Committed at subversion revision 1430957.
When we address this issue, we should adjust RestrictedVTITest.test_12_6036()
to verify that projections are passed through also.
Touches the following file:
M
java/testing/org/apache/derbyTesting/functionTests/tests/lang/RestrictedVTITest.java
> If you wrap a SELECT * view around a table, all of the columns are read from
> the base row even when you SELECT only a subset of the view columns.

> This also affects SELECTs from views wrapping RestrictedVTIs. Restrictions
> are pushed into a restricted VTI if you wrap it in a view. However,
> projections are not. I will attach a script showing this problem.
