return tgt \ join_project(tgt, neg, c1, .., cN, d1, .. , dN)
We have most of the facilities required for a join project operation.
For example, the filter_project function uses both equalities and deleted columns.
- Lipstick service:
- filter_proj_fn uses both a bit_vector and a svector<bool> for representing removed bits.
This is due to underlying routines using different types for the same purpose.
