Question

I want to write a User-Defined function in SQL SERVER which will take a string as parameter and check it if it has a ‘/’ in the string, it’ll return 1 and otherwise 0.

Please guide me to achieve this scenario.

Unsure why you’d want to make a UDF when TSQL’s CHARINDEX is all you really need.

Try something like this if you really need a UDF:

CREATE FUNCTION dbo.HasSlash(@input varchar(max))
RETURNS bit
AS
BEGIN        
     RETURN CHARINDEX( '/',@input);
END;

Use it like this:

SELECT dbo.HasSlash('hello/world'); -- returns 1
SELECT dbo.HasSlash('hello world'); -- returns 0
