> When the query has a where clause that has an integer column checking against being "not in" a decimal column, the decimal column is being changed to null, causing incorrect results.
> This is a sample query of a failure:
> select count(*) from my_tbl where int_col not in (355.8);
> Since the int_col can never be 355.8, one would expect all the rows to be returned, but it is changing the 355.8 into a null value causing no rows to be returned.
