我想将我的 Hijri Shamsi 日期“92/2/3”转换为这种格式:“92/02/03”

使用此代码,我收到此错误:将 varchar 数据类型转换为 datetime 数据类型导致值超出范围。

Declare @Str Varchar(10) = '92/2/3'
Select Convert(Varchar(10), Convert(DateTime, @Str), 111)

如何更改日期格式?

  1. 既然你没有世纪,你应该使用11,而不是111你的转换代码
  2. 您需要在内部转换中使用 11 来告诉它它转换的格式是什么

    Declare @Str Varchar(10) = '92/2/3'    
    Select Convert(Varchar(10), Convert(DateTime, @Str,11), 11)

使用此函数以您请求的格式将公历日期转换为回历(Shamsi)日期:

CREATE FUNCTION [dbo].[ShamsiDate]
        (
          @ChirsDate SMALLDATETIME
        )
    RETURNS CHAR(10)
    AS
        BEGIN
            DECLARE @SolarDate CHAR(10)
            DECLARE @Day CHAR(2)
            DECLARE @Mon CHAR(2)
            DECLARE @SDay INT
            DECLARE @SMon INT
            DECLARE @SYear INT
            SET @SYear = dbo.ShamsiDatePart(@ChirsDate, 'Y')
            SET @SMon = dbo.ShamsiDatePart(@ChirsDate, 'M')
            SET @SDay = dbo.ShamsiDatePart(@ChirsDate, 'D')
            IF @SMon <= 9
                SELECT  @Mon = '0' + CONVERT(CHAR(1), @SMon)
            ELSE
                SELECT  @Mon = CONVERT(CHAR(2), @SMon)
            IF @SDay <= 9
                SELECT  @Day = '0' + CONVERT(CHAR(1), @SDay)
            ELSE
                SELECT  @Day = CONVERT(CHAR(2), @SDay)
            SELECT  @SolarDate = CONVERT(CHAR(4), @SYear) + '/' + @Mon + '/'
                    + @Day
            RETURN @SolarDate
        END

    CREATE FUNCTION [dbo].[ShamsiDatePart]

如果您使用的是 SQL Server 2012,则可以使用以下解决方案。

Declare @Str varchar(10) = '92/2/3'    
Select Format(Convert(Date, @Str,11),'yy/MM/dd')
