Need a quick workaround to declaring arrays in SQL Server?

-- Trying to accomplish something like this?
int[] @list = {1864, 1966} -- INCORRECT SQL 
SELECT * FROM Employees
WHERE id IN @list

Here’s a workaround

DECLARE @list TABLE (id int)          -- create an int[] "array"
INSERT @list VALUES (1864)            -- hardcode values
INSERT @list VALUES (1966)            -- hardcode values
SELECT * FROM Employees               -- my query
WHERE id IN (SELECT id FROM @list)    -- use the int[] array
