Question

我想在sql server中将我的日期时间转换为波斯语日期时间。我的日期时间是MM / DD / YYYY格式。在sql server中是否有任何功能可以执行此操作，因为当我想要hijri datetime时我会使用此

 select CONVERT(VARCHAR(40), getdate(), 131) //Output is 14/08/1432 5:02:01:197PM

我正在使用sql server 2008

Answer 1

我知道现在为时已晚，但也许对我这样的人有用。

您应该为此转换编写一个SQL函数，如下所示： Converting Gregorian to Persian Date

然后像这样使用它：

SELECT dbo.[UDF_Gregorian_To_Persian]('2013-08-24')

Answer 2

我知道回答这个问题为时已晚，但我已经提交了我长时间使用的功能而没有任何错误，我见过的所有其他方法都存在闰年问题：

CREATE FUNCTION [CalculatePersianDate] ( @intDate DATETIME )
RETURNS NVARCHAR(max)
BEGIN

DECLARE @shYear AS INT ,@shMonth AS INT ,@shDay AS INT ,@intYY AS INT ,@intMM AS INT ,@intDD AS INT ,@Kabiseh1 AS INT ,@Kabiseh2 AS INT ,@d1 AS INT ,@m1 AS INT, @shMaah AS NVARCHAR(max),@shRooz AS NVARCHAR(max),@DayCnt AS INT
DECLARE @DayDate AS NVARCHAR(max)

SET @intYY = DATEPART(yyyy, @intDate)

IF @intYY < 1000 SET @intYY = @intYY + 2000

SET @intMM = MONTH(@intDate)
SET @intDD = DAY(@intDate)
SET @shYear = @intYY - 622
SET @DayCnt = 5

IF ( ( @intYY - 1992 ) % 4 = 0) SET @Kabiseh1 = 0 ELSE SET @Kabiseh1 = 1

IF ( ( @shYear - 1371 ) % 4 = 0) SET @Kabiseh2 = 0 ELSE SET @Kabiseh2 = 1

SET @m1 = 1

WHILE ( @m1 != @intMM ) OR ( @d1 != @intDD )
BEGIN

  SET @d1 = @d1 + 1
  SET @DayCnt = @DayCnt + 1

  IF 
  (@d1 = 32 AND (@m1 = 1 OR @m1 = 3 OR @m1 = 5 OR @m1 = 7 OR @m1 = 8 OR @m1 = 10 OR @m1 = 12))
  OR
  (@d1 = 31 AND (@m1 = 4 OR @m1 = 6 OR @m1 = 9 OR @m1 = 11))
  OR

    SET @d1 = 1
  END

  IF @m1 > 12
  BEGIN
    SET @intYY = @intYY + 1
    SET @m1 = 1
  END

  IF @DayCnt > 7 SET @DayCnt = 1

 SET @shDay = @shDay + 1

  IF

  OR

    SET @shDay = 1
  END

  IF @shMonth > 12

    SET @shYear = @shYear + 1
    SET @shMonth = 1
  END

END

/*

Answer 3

开箱即用，没有。

您必须编写自己的UDF，但CodePlex和another上有一个

Answer 4

convert Jalali to Georgian and Georgian to Jalali

试试这个链接。您可以在SQL服务器中添加一些功能，并在需要时调用它们。

Answer 5

尝试一下：

select format(getdate() , 'yyyy/MM/dd', 'fa-ir')

Answer 6

SQL Server 2016中的最佳方法

示例：

SELECT FORMAT(GETDATE(), 'yyyy/MM/dd-HH:mm:ss', 'fa')

答案：

1398/10/08-05:37:59

Answer 7

我认为最好的解决方案是使用SQLCLR-Jalali-Date-Utility。它具有简单明了的安装指南和易于使用的功能。此外，您可以无限制地定义转换日期的格式。实际上，您可以使用standard time formatting来定义转换日期的形状。

在GitHub页面中提供了几个示例。

0101111101100001

0110000101011111
0011000010101111

1010111100110000

Answer 8

您可以使用此功能将其转换为shamsi。

第一个功能。创建函数[dbo]。[ToPersianDate]（@ dt [datetime]）使用执行者调用返回nvarchar 如外部名称[PersianSQLFunctions]。[UserDefinedFunctions]。[ToPersianDate]

GO

第二个功能。设置ANSI_NULLS OFF 开始

将QUOTED_IDENTIFIER设置为OFF 开始

创建功能[dbo]。[ToPersianDate]（@ dt [datetime]）使用执行者调用返回nvarchar 如外部名称[PersianSQLFunctions]。[UserDefinedFunctions]。[ToPersianDate]

GO

第三功能。创建功能[dbo]。[fnToShamsiDate] （ @d DateTime ）返回NVARCHAR（10）如开始 -在这里声明返回变量十进制@RV NVARCHAR（10）如果（@d）为NULL，则返回NULL; 其他选择@RV = DBO.ToPersianDate（@D）; -返回函数结果返回@RV

END

GO

您还可以通过此功能找到假的月份

创建函数[dbo]。[fnGetShamsiMonth] （ @GregorianDate日期）返回nvarchar（2）如开始声明@ShamsiMonth nvarchar（2），@ShamsiDate nvarchar（10）;

set @ShamsiDate = confsys.dbo.fnToShamsiDate(@GregorianDate);

set @ShamsiMonth = SUBSTRING(@ShamsiDate,6,2);

return @ShamsiMonth

结束开始

示例

选择confsys.dbo.fnToShamsiDate（getdate（））结果是1397/12/29

获得假月份选择confsys.dbo.fnGetShamsiMonth（GETDATE（））;
