Use of temporary functions or procedure within a script

Question

I am using SQL Server 2012, i have a script by which i am inserting values to a table, in that script i have to convert the format of some DateTime variables on the basis of two parameters.

I can do it using CASE or if condition in sql. I am not allowed to make any Function or procedure in the database to which i can refer.

Is there any other way like creating a temporary function or temporary procedure within the script to apply condition alter the format for Datetime values?

Yes you can:

CREATE PROCEDURE #usp_TempOne 
@Input INT,
@Output INT OUTPUT
as 
SET @Output = @Input * 2
RETURN
GO
DECLARE @i INT = 10, @o INT;
EXEC #usp_TempOne @i, @o OUTPUT
SELECT @o
