Kathey Marsden commented on DERBY-3310:
---------------------------------------
I think then I misinterpreted your suggestion:
>Setting up a NormalizeResultSetNode is spread over three locations, the class
>itself (very little, it's almost acting like a C struct),
>the genNormalizeResultSetNode method and then copyLengthsAndTypesToSource. A
>good O-O implementation would have
>the logic to create a NormalizeResultSetNode self-contained in
>NormalizeResultSetNode.
I was endeavoring to move the existing logic into NormalizeResultSetNode.
Perhaps some
other first steps are more appropriate. Any advice is appreciated. I do feel
however that
I am getting further away, not closer to resolving DERBY-3310.

> The following code
> CREATE TABLE U (SNAME VARCHAR(32000), TNAME VARCHAR(32000), C1 BIGINT);
> -- This triggers an ASSERT (because 2 is INTEGER and not BIGINT)
> INSERT INTO U(SNAME, TNAME, C1) SELECT DISTINCT SCHEMANAME, TABLENAME, 2
> FROM SYS.SYSTABLES T JOIN SYS.SYSSCHEMAS S ON T.SCHEMAID = S.SCHEMAID;
> gives
> ERROR XJ001: Java exception: 'ASSERT FAILED col1.getClass() (class
