SQLServer中日期处理与时间段处理

把SQLServer 中日期处理与时间段处理记录下来

直接上代码

SELECT 
dddd,
CAST(DATEDIFF(SECOND,'1970-01-01 00:00:00',DATEADD(MINUTE,s.number*1,@DECDT)) - 32400 AS BIGINT) * 1000 st,
CONVERT(VARCHAR(19),DATEADD(MINUTE,s.number*1,@DECDT),120) dt 
FROM master..values s 
WHERE s.type = 'P' 
AND s.number <@DIFFMINUTE),zd AS (
SELECT dddd,vvvv,tttt 
FROM XXXXXX 
WHERE xxxx = @DEVICEID 
AND date >= @DECDATE 
AND date <= @LASTDECDATE

借助了功能表master..values。
