Answer 1

Hi @Shahab a

SQL Server supports many formats, most of which depend on your settings, so sometimes these settings may or may not work.
The solution to this problem is to use a date format that SQL Server supports. This format is suitable for any situation, regardless of your SQL Server language and date formatting settings.
YYYYMMDD format, you should be able to work with any version of SQL Server and any language and date formatting settings in SQL Server，As ErlandSommarskog said.

DATEDIFF(DAY,'20220506','20220701') > 3

Answer 2

Try:

   SELECT    DATEDIFF(DAY, '20220506', '20220701') > 3  

The format YYYYMMDD without any delimiter is safe. That is, it works no matter the SET DATEFORMAT setting.

Answer 3

Try this :

Select DATEDIFF(DAY, '05/06/2022' , '07/01/2022')

Your system is using British/French:

--103 = dd/mm/yyyy
