Log:
DERBY-1784
contributed by Yip Ng
committing derby1784-10.1-diff01.txt patch as backport of issue to 10.1 branch.
After studying the
compiler code abit more, I found that DML statements such as INSERT, UPDATE and
DELETE also suffer from the same problem (they use different bind logic)
With that said, this patch attempts to address all the stated problems above
when column reference is qualified with a synonym table name.
The fundamental problem is that Derby does not keep the original unbound table
name around once the synonym is resolved. So the fix is to address this case
and apply the qualification properly.
In the VIEW resolution case, the system needs to preserve the synonym name as
VIEW gets expanded to a subquery, the name to be set should be the exposed
name of the table and not the resolved table name.
For * expansion in the SELECT list, if the FROM clause happens to be a synonym,
the system should prepend it with the unbound name and not the resolved table
name. This way the binding logic is normalized.
For DML cases, the synonym name needs to be normalized to its base table so tha
setColumnDescriptor can apply correctly. When the system binds the expression
for this result column, it will resolve this properly since the column binding
logic are in the respective FromTable subclasses implementation where they
will use the exposed name this time to check for qualification.
I wrote more testcases for synonym.sql but I found out that this SQL file is
actually not part of derbylang suite, so the patch added this back to the test
bucket.
