转换回历沙姆西日期格式TSQL

Question

我想将我回历沙姆西日期'92/2/3'为此格式：'92/02/03'

有了这个代码，我得到这个错误：将varchar数据类型转换为日期时间数据类型导致超出范围值。

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

如何更改日期格式？

Answer 1

1. 既然你没有百年，你应该使用11，不111作为转换代码

2. 您需要使用11在内部转换来告诉它这是什么转换格式FROM

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

Answer 2

您可以使用下面给出的解决方案，如果您使用的是SQL Server 2012的

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

使用此功能，公历日期转换为回历（沙姆西）更新您的请求的格式：

CREATE FUNCTION [dbo].[ShamsiDate]
