> Queries like 
> SELECT col1 BETWEEN 0 and 10 from T;
> fail in vectorized mode. Support needs to be implemented for a BETWEEN expression in the SELECT list, comparable to how it was added for comparison operators (<, >, ...). These were done by adding new, templates that return a value for a comparison instead of applying a filter. See ColumnCompareScalar.txt under ql/src/gen for an example.
