When building queries for "Inpatient" visit dimension term, generated SQL no longer contains the visit date restriction parameters if dates are restricted on the front end. For example, we query simply "Inpatient" for 01/01/13 - 01/31/13 and get the same result as when we query with no date restrict for the same term. In 1.5, the date restrict worked on non-observation_fact terms, but on 1.6 it doesn't seem to function appropriately. Tested in the Partners demo domain with the same result. See below for 1) example of 1.5 query with visit dim date restrict and 2) example of 1.6 query with date restrict on the front end of the web client and workbench, but not in the generated SQL. Was this function deprecated for some reason with the upgrade to 1.6? I cannot find any documentation on this particular issue.
