cd_dep_count, cd_dep_employed_count are not selected but are part of order by.
Not sure if this would a simple fix. [~pxiong] Have you looked into this ? Any
idea what would it take to fix this? Quick look at error stack suggests that it
is giving up during operator tree generation while trying to resolve column
names (probably for oder by )

> and i_category in ('Jewelry', 'Sports', 'Books')
> and cs_sold_date_sk = d_date_sk
