How to pass parameters to Table Valued Function

Question

I want to do something like

select * from tvfHello(@param) where @param in (Select ID from Users)

Answer 1

The following works in the AdventureWorks database:

CREATE FUNCTION dbo.EmployeeByID(@employeeID int)
RETURNS TABLE
AS RETURN
(
    SELECT * FROM HumanResources.Employee WHERE EmployeeID = @employeeID
)
GO


DECLARE @employeeId int

set @employeeId=10

select * from 
EmployeeById(@employeeId) 
WHERE @EmployeeId in (SELECT EmployeeId FROM HumanResources.Employee)

EDIT

Based on Kristof expertise I have updated this sample if your trying to get multiple values you could for example do:

select * 
from HumanResources.Employee e
CROSS APPLY  EmployeeById(e.EmployeeId)
WHERE e.EmployeeId in (5,6,7,8)
