How Can I Use Parameters with Views in Microsoft SQL Server?

Accessing Parameters within SQL Views

In Microsoft SQL Server, it is not possible to directly pass parameters to views. Attempting to create a view with a parameter, as demonstrated by the following code, will result in an error:

create or replace view v_emp(eno number) as select * from emp where emp_id=&eno;

Alternative Method: Stored Functions

As an alternative solution, parameters can be utilized within stored functions. A stored function can be implemented in the following manner:

CREATE FUNCTION v_emp (@pintEno INT)
RETURNS TABLE
AS
RETURN
   SELECT * FROM emp WHERE emp_id=@pintEno;

Once implemented, the stored function can be used as if it were a view, by executing the following query:

SELECT * FROM v_emp(10)
