Method Two

DateTime.ToString ("Yyyy-mm-dd") is used in C #, and DateTime.ToString ("mm/dd/yyyy") is a way to convert dates and strings that are not available in SQL Server. As a function, the functions are similar to the datetime.tostring ("Formatprovide") method in. NET, but only the date part is implemented, and interested friends can supplement the time part.

Create function fn_datetostring (@date datetime, @format varchar (20))

Returns varchar (20)

As

Begin

DECLARE @result varchar (20)

Select @result = (replace (replace (@format, ' yyyy ', ' +substring ' (CONVERT (char (8), @date, 3), 7,2)), ' mm ', SUBSTRING (CONVERT (char (8), @date, 3), 4,2), ' DD ', substring (CONVERT (char (8), @date, 3), 1,2))

Return @result

End

Use:

Select Dbo.fn_datetostring (getdate (), ' yyyy-mm-dd ')
