ms sql server中实现的unix时间戳函数(含生成和格式化,可以和mysql兼容)
直接上代码:
CREATEFUNCTIONUNIX_TIMESTAMP(@ctimestampdatetime)RETURNSinteger AS BEGIN /*Functionbody*/ declare@returninteger SELECT@return=DATEDIFF(SECOND,{d'1970-01-01'},@ctimestamp) return@return END CREATEFUNCTIONfrom_unixtime(@tsinteger)RETURNSdatetime AS BEGIN /*Functionbody*/ declare@returndatetime select@return=DATEADD(second,@ts,{d'1970-01-01'}) return@return END
用法
跟MySQL下的一样类似:
selectdbo.UNIX_TIMESTAMP('2013-1-1') selectdbo.from_unixtime(2145000000)
