我有Table1,我需要让它看起来像Table2:

表格1

      3       |  15:10
      7       |  15:15

      2       |  15:40
      3       |  15:47

create FUNCTION [dbo].[fn_GetActivityLogsArranger] (@time AS nvarchar(max))
RETURNS nvarchar(max)
AS
BEGIN
    declare @Return varchar(30)

    select @Return = 
        case

            when @time between '15:30' and '16:00' then '15:30-16:00'
            when @time between '16:00' and '16:30' then '16:00-16:30'
            when @time between …

嗨,我想运行一个if语句但是在我所有的AS别名附近都会出现语法错误,我做错了什么？

SELECT

IF @Origin = 'ALL'


(SELECT COUNT(*)  FROM TBL_PARTORDER INNER JOIN TBL_REPAIR_ORDER ON TBL_PARTORDER.ORDERID = TBL_REPAIR_ORDER.ORDERID INNER JOIN TBL_PROPERTY ON TBL_REPAIR_ORDER.PROPREF = TBL_PROPERTY.PROPREF WHERE (TBL_PARTORDER.RAISED IS NOT NULL) AND (TBL_PARTORDER.RAISED BETWEEN CONVERT(DATETIME,@STARTDATE, 103) AND DATEADD(hh,23,CONVERT(DATETIME,@ENDDATE, 103))) AND (TBL_PROPERTY.CONTRACT = @CONTRACT) AND DATEDIFF(mi, TBL_PARTORDER.RAISED, TBL_PARTORDER.RECEIVED) <= 60) AS OneHour,
