I suspect you need a SELECT verb before COUNT: SQL COUNT(), AVG() and SUM() Functions[^].

Solution 1

You can't assign a value to an input parameter like that:

SQL

CREATE FUNCTION task_hospitals
(@vic_id INT, @HOS INT ) RETURNS INT
AS
BEGIN
RETURN (SELECT COUNT(*)
        FROM patients
        WHERE victim_id = @vic_id);
END
