ESQL: INLINE STATS null grouping/joining #139887
Description
Description
There's a difference between how STATS behaves compared to INLINE STATS caused by null grouping/joining that we should look into:
ROW x = 1
| STATS c = COUNT(*) BY n = null
| KEEP c, n
| LIMIT 1
yields:
c | n
---------------+---------------
1 |null
However,
ROW x = 1
| INLINE STATS c = COUNT(*) BY n = null
| KEEP c, n
| LIMIT 1
yields:
c | n
---------------+---------------
null |null
