Question

 declare @FromDate varchar(30)
 set @FromDate= '2014-06-06'

我需要将@FromDate转换为datetime：

set @fromdate = convert(datetime,  @fromdate, 126)

然后我需要格式为'2014-06-06 00:00:00.000'的输出。

有人可以建议如何执行此转换吗？

Answer 1

DECLARE @FromDate VARCHAR(30) SET @FromDate = '2014-06-06'
DECLARE @FromDateDT DATETIME SET @FromDateDT =  @FromDate
-- DECLARE @FromDateDT DATETIME SET @FromDateDT =  CONVERT(DATETIME, @FromDate) -- It's the same as line above
SET @FromDate = CONVERT(VARCHAR, @FromDateDT, 120)
SELECT  @FromDate
SET @FromDate = CONVERT(VARCHAR, @FromDateDT, 121)
SELECT  @FromDate

或简单

SELECT CONVERT(VARCHAR, CONVERT(DATETIME, '2014-06-06'), 121)

其他一些格式：
