on sql server configured case-insensitive, group by can have interesting results when [n][var]char column not first group by column. essentially, looks whatever row encounters "first" (where "first" undefined in absence of order): wins grouping. example: select x.[day], x.[name], count(1) [count] ( select 1 [day], 'a' [name] union select 1, 'a' union select 2, 'a' union select 2, 'a' ) x group x.[day], x.[name] which returns, me: day name count ----------- ---- ----------- 1 2 2 2 using min(x.[name]) has no effect, since grouping happened. i can't add order by before group by , illegal; , adding order by after group by defines output order after grouping - still gives a , a . so: there sane way of doing capitalization @ least consistent groupings? (i'll leave day problem of being consistent separate runs) desired output, either: day nam...
