1055469073,I_kwDOBm6k_c4-6S4R,1513,Research: CTEs and union all to calculate facets AND query at the same time,9599,closed,0,,,12,2021-11-16T22:26:45Z,2021-11-16T23:41:46Z,2021-11-16T23:41:46Z,OWNER,,"Consider this page: https://global-power-plants.datasettes.com/global-power-plants/global-power-plants?_search=plant&_facet=owner&_facet=country_long&_facet=primary_fuel

Datasette needs to run the main query for the rows on that page, a count query for the total query, then a separate query for each of those three specified facets.

This is a `_search=` query, so it needs to execute the FTS code once for the rows, again for the count, and then three more times for each of the facets.

Could running that query as a CTE and doing the other queries as part of the same large query produce significant speed improvements?",107914493,issue,,,"{""url"": ""https://api.github.com/repos/simonw/datasette/issues/1513/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,completed
440222719,MDU6SXNzdWU0NDAyMjI3MTk=,448,_facet_array should work against views,9599,closed,0,,3268330,12,2019-05-03T21:08:04Z,2021-11-16T01:32:05Z,2021-11-16T01:19:40Z,OWNER,,"I created this view: https://json-view-facet-bug-demo-j7hipcg4aq-uc.a.run.app/russian-ads-8dbda00/ads_with_targets

```
CREATE VIEW ads_with_targets as select ads.*, json_group_array(targets.name) as target_names from ads
  join ad_targets on ad_targets.ad_id = ads.id
  join targets on ad_targets.target_id = targets.id
  group by ad_targets.ad_id
```

When I try to apply faceting by array it appears to work at first: https://json-view-facet-bug-demo-j7hipcg4aq-uc.a.run.app/russian-ads/ads_with_targets?_facet_array=target_names

But actually it's doing the wrong thing - the SQL for the facets uses rowid, but rowid is not present on views at all! These results are incorrect, and clicking to select a facet will fail to produce any rows: https://json-view-facet-bug-demo-j7hipcg4aq-uc.a.run.app/russian-ads/ads_with_targets?_facet_array=target_names&target_names__arraycontains=people_who_match%3Ainterests%3AAfrican-American+Civil+Rights+Movement+%281954%E2%80%9468%29

Here's the SQL it should be using when you select a facet (note that it does not use a rowid):

https://json-view-facet-bug-demo-j7hipcg4aq-uc.a.run.app/russian-ads?sql=select+*+from+ads_with_targets+where+id+in+%28%0D%0A++++++++++++select+ads_with_targets.id+from+ads_with_targets%2C+json_each%28ads_with_targets.target_names%29+j%0D%0A++++++++++++where+j.value+%3D+%3Ap0%0D%0A++++++++%29+limit+101&p0=people_who_match%3Ainterests%3ABlack+%28Color%29

So we need to do something a lot smarter here. I'm not sure what the fix will look like, or even if it's feasible given that views don't have a rowid to hook into so the JSON faceting SQL may have to be completely rewritten.
