Review Comment:
We typically do not pass nulls in the List<PColumn> and the downstream code
paths are not explicitly checking for nulls, thus gives a NullPointer
exception.
If we skip the column all together then it gives another exception, I guess
since there is a column count mismatch OR and some other logic error (haven't
had a chance to debug)
Error: ERROR 203 (22005): Type mismatch. expected: [UNSIGNED_TINYINT] but
was: BIGINT at SQLINDEXTYPE argument 1 (state=22005,code=203)
