[转]Sql server2005中如何格式化时间日期

SELECT convert(varchar, getdate(), 100) -- mon dd yyyy hh:mmAM (or PM)
SELECT convert(varchar, getdate(), 101) -- mm/dd/yyyy - 10/02/2008
SELECT convert(varchar, getdate(), 102) -- yyyy.mm.dd -- 2008.10.02
SELECT convert(varchar, getdate(), 103) -- dd/mm/yyyy
SELECT convert(varchar, getdate(), 104) -- dd.mm.yyyy
SELECT convert(varchar, getdate(), 105) -- dd-mm-yyyy
SELECT convert(varchar, getdate(), 106) -- dd mon yyyy
SELECT convert(varchar, getdate(), 107) -- mon dd, yyyy
SELECT convert(varchar, getdate(), 108) -- hh:mm:ss
SELECT convert(varchar, getdate(), 109) -- mon dd yyyy hh:mm:ss:mmmAM (or PM)
SELECT convert(varchar, getdate(), 110) -- mm-dd-yyyy
SELECT convert(varchar, getdate(), 111) -- yyyy/mm/dd
SELECT convert(varchar, getdate(), 112) -- yyyymmdd
SELECT convert(varchar, getdate(), 113) -- dd mon yyyy hh:mm:ss:mmm
SELECT convert(varchar, getdate(), 114) -- hh:mm:ss:mmm(24h)
SELECT convert(varchar, getdate(), 120) -- yyyy-mm-dd hh:mm:ss(24h)
SELECT convert(varchar, getdate(), 121) -- yyyy-mm-dd hh:mm:ss.mmm
SELECT convert(varchar, getdate(), 126) -- yyyy-mm-ddThh:mm:ss.mmm

-- 利用字符串函数创建不同的日期格式
SELECT replace(convert(varchar, getdate(), 111), '/', ' ') -- yyyy mm dd
SELECT convert(varchar(7), getdate(), 126) -- yyyy-mm
SELECT right(convert(varchar, getdate(), 106), 8) -- mon yyyy

--通用的日期转换函数
CREATE FUNCTION dbo.fnFormatDate (@Datetime DATETIME, @FormatMask VARCHAR(32))RETURNS VARCHAR(32)AS
BEGIN
DECLARE @StringDate VARCHAR(32)
SET @StringDate = @FormatMask
IF (CHARINDEX ('YYYY',@StringDate) > 0)
SET @StringDate = REPLACE(@StringDate, 'YYYY',DATENAME(YY, @Datetime))
IF (CHARINDEX ('YY',@StringDate) > 0)
SET @StringDate = REPLACE(@StringDate, 'YY',RIGHT(DATENAME(YY, @Datetime),2))
IF (CHARINDEX ('Month',@StringDate) > 0)
SET @StringDate = REPLACE(@StringDate, 'Month',DATENAME(MM, @Datetime))
IF (CHARINDEX ('MON',@StringDate COLLATE SQL_Latin1_General_CP1_CS_AS)>0)
SET @StringDate = REPLACE(@StringDate, 'MON',LEFT(UPPER(DATENAME(MM, @Datetime)),3))
IF (CHARINDEX ('Mon',@StringDate) > 0)
SET @StringDate = REPLACE(@StringDate, 'Mon',LEFT(DATENAME(MM, @Datetime),3))
IF (CHARINDEX ('MM',@StringDate) > 0)
SET @StringDate = REPLACE(@StringDate, 'MM',RIGHT('0'+CONVERT(VARCHAR,DATEPART(MM, @Datetime)),2))
IF (CHARINDEX ('M',@StringDate) > 0)
SET @StringDate = REPLACE(@StringDate, 'M',CONVERT(VARCHAR,DATEPART(MM, @Datetime)))
IF (CHARINDEX ('DD',@StringDate) > 0)
SET @StringDate = REPLACE(@StringDate, 'DD',right('0'+DATENAME(DD, @Datetime),2))
IF (CHARINDEX ('D',@StringDate) > 0)
SET @StringDate = REPLACE(@StringDate, 'D',DATENAME(DD, @Datetime))
RETURN @StringDate
END

--调用示例: SELECT dbo.fnFormatDate (getdate(), 'MM/DD/YYYY')  --03/06/2011
