Gian Merlino c9faf3e148 Add SQL GROUPING SETS support. (#9122) ... * Add SQL GROUPING SETS support. Built on top of the subtotalsSpec feature in the groupBy query. This also involves two changes to subtotalsSpec: - Alter behavior so limitSpec is applied after subtotalsSpec, rather than applied to each grouping set. This is more in line with SQL standard behavior. I think it is okay to make this change, since the old behavior was not documented, so users should hopefully not be depending on it. - Fix a bug where virtual columns were included in the subtotal queries, but they should not have been. Also fixes two bugs in query equality checking: - BaseQuery: Use getDuration() instead of "duration" in equals and hashCode, since the latter is lazily initialized and might be null in one query but not the other. - GroupByQuery: Include subtotalsSpec in equals and hashCode. * Fix bugs. * Fix tests. * PR updates. * Grouping class hygiene.		2020-02-26 08:52:39 -08:00
