SELECT SYSDATETIME() AS SYSDATETIME
    ,SYSDATETIMEOFFSET() AS SYSDATETIMEOFFSET
    ,SYSUTCDATETIME() AS SYSUTCDATETIME
    ,CURRENT_TIMESTAMP AS CURRENT_TIMESTAMP
    ,GETDATE() AS GETDATE
    ,GETUTCDATE() AS GETUTCDATE;
下面是结果集：

SYSDATETIME() 2007-04-30 13:10:02.0474381

SYSDATETIMEOFFSET()2007-04-30 13:10:02.0474381 -07:00
