Eric Hanson commented on HIVE-4922:
-----------------------------------
I verified that comparisons with a scalar on the left and a column on the right
run end-to-end, using these queries, which all run vectorized:
select l_orderkey, l_shipmode from lineitem_orc where l_orderkey = 1 and 'MAIL'
= l_shipmode;
select l_orderkey, l_shipmode from lineitem_orc where l_orderkey = 1 and 'MAIL'
<> l_shipmode;
select l_orderkey, l_shipmode from lineitem_orc where l_orderkey = 1 and 'MAIL'
<= l_shipmode;
select l_orderkey, l_shipmode from lineitem_orc where l_orderkey = 1 and 'MAIL'
>= l_shipmode;
select l_orderkey, l_shipmode from lineitem_orc where l_orderkey = 1 and 'MAIL'
< l_shipmode;
select l_orderkey, l_shipmode from lineitem_orc where l_orderkey = 1 and 'MAIL'
> l_shipmode;
> create template for string scalar compared with string column

> Issue Type: Sub-task
> Affects Versions: vectorization-branch
> Reporter: Eric Hanson
> Assignee: Eric Hanson
>
> Create a template to generate classes to handle comparisons with a scalar on
> the left and a column on the right.
> This allows queries similar to the following to run vectorized:
> select l_orderkey, l_shipmode
> from lineitem_orc
> where l_orderkey = 1 and 'M' > l_shipmode;
