Cara mengonversi string DateTime ke DateTime di SQL Server

Di SQL Server 2008 anda dapat menggunakan datetimeoffset tipe data.

SELECT [Result] = CONVERT(datetimeoffset, '2005-08-08T00:01:00+01:00', 127)

Keluaran:

Result
----------------------------------
2005-08-08 00:01:00.0000000 +01:00

Di SQL Server 2005 dan sebelumnya Anda dapat menghitung tanggal dan offset UTC:

SELECT [LocalDate], [OffsetMinutes], [UtcDate]
FROM
(
    SELECT [IsoDate] = '2007-08-08T00:01:00+01:00'
) A
OUTER APPLY
(
    SELECT [LocalDate] = CONVERT(datetime, LEFT([IsoDate], 19), 126)
    , [OffsetMinutes] =
        CASE SUBSTRING([IsoDate], 20, 1)
            WHEN '+' THEN +1
            WHEN '-' THEN -1
        END
        * DATEDIFF(minute, 0,
            CAST(SUBSTRING([IsoDate], 21, 5) + ':00' AS datetime))
    WHERE [IsoDate] LIKE '____-__-__T__:__:__[+-]__:__'
) B
OUTER APPLY
(
    SELECT [UtcDate] = DATEADD(minute, -[OffsetMinutes], [LocalDate])
) C

Keluaran:

LocalDate               OffsetMinutes UtcDate
