Marios Trivyzas b0cb7bf229 SQL: Fix issue with GROUP BY YEAR() (#49559) ... Grouping By YEAR() is translated to a histogram aggregation, but previously if there was a scalar function invloved (e.g.: `YEAR(date + INTERVAL 2 YEARS)`), there was no proper script created and the histogram was applied on a field with name: `date + INTERVAL 2 YEARS` which doesn't make sense, and resulted in null result. Check the underlying field of YEAR() and if it's a function call `asScript()` to properly get the painless script on which the histogram is applied. Fixes: #49386 (cherry picked from commit 93c37abc943d00d3a14ba08435d118a6d48874c7)		2019-11-26 14:11:11 +01:00
