treatments value constraints: needed cleanup and decisions

Open gsrohde opened this issue 9 years ago • 1 comments

control

  • [ ] Decide how to handle cases where control is NULL
  • [ ] Add not NULL constraint
  • [ ] Decide what other constraints apply to control
  • [ ] Add them

Details

control is NULL in 190 rows.

From the Uniqueness portion of the constraints spreadsheet: "there must be a control for each (citation_id, site_id) tuple". "A control" means a treatment for which control = true. The meaning of this is not clear, however, since site_id and citation_id are not columns of this table.
