Rick Hillegas updated DERBY-5554:
---------------------------------
Attachment: derby-5554-04-ac-remapVTIarg.diff
Attaching derby-5554-04-ac-remapVTIarg.diff, a new rev of the
argument-remapping approach. I am running regression tests now.
This rev is simpler than the previous attempt. It may also handle more cases
than the previous patch. The patch merely touches FromVTI.
Touches the following files:
-----------
M java/engine/org/apache/derby/impl/sql/compile/FromVTI.java
1) At bind-time, we save a reference to every FROM list element referenced by
the VTI's arguments.
2) At code-generation time, we build an argument expression from the
ResultColumn actually used when the FROM list element was code generated.
-----------
M
java/testing/org/apache/derbyTesting/functionTests/tests/lang/SysDiagVTIMappingTest.java
Adds Bryan's original query and Knut's re-ordered query as test cases.
