It's not really very easy, since SQL does not have any concept of arrays.
However, you could pass them through as a delimited string, and break it into a temporary table in your procedure:
Pass a list as a string parameter:
DECLARE @INSTR as VARCHAR(MAX)
SET @INSTR = '2,3,177,'
DECLARE @SEPERATOR as VARCHAR(1)
DECLARE @SP INT
DECLARE @VALUE VARCHAR(1000)
SET @SEPERATOR = ','
CREATE TABLE #tempTab (id int not null)
WHILE PATINDEX('%' + @SEPERATOR + '%', @INSTR ) <> 0
BEGIN
SELECT @SP = PATINDEX('%' + @SEPERATOR + '%',@INSTR)
SELECT @VALUE = LEFT(@INSTR , @SP - 1)
SELECT @INSTR = STUFF(@INSTR, 1, @SP, '')
INSERT INTO #tempTab (id) VALUES (@VALUE)
END
SELECT * FROM myTable WHERE id IN (SELECT id FROM #tempTab)
DROP TABLE #tempTab
