问题 I have a variable of DateTime type in SQL. Just need to have Date part of it. please Help? 回答1: SELECT DATEADD(dd, 0, DATEDIFF(dd, 0, GETDATE())) The result is: “2009-07-14 00:00:00.000” Edit : guess the next variant is more common: SELECT DATEADD(dd, DATEDIFF(dd, 0, GETDATE()), 0) because of the day pattern can be easily changed to week or month pattern. It is very useful when the GROUP BY clause should group by week of month (reports). 回答2: This has been asked and answered before on Stack

问题 I call several sql files using: :r C:\Scripts\Script1.sql :r C:\Scripts\Script2.sql :r C:\Scripts\Script3.sql I have this idea about the :r call from here: TransactSQL to run another TransactSQL script.

Select trans_type, count(1) from mytable group by trans_type This is grouping the counts for 'S' along with the 's' counts. Is there any way to force a query to be cap
