Depending on your SQL-Server Verion you can use a Table-Valued Function like in this short example

Select * from dbo.test1
Where ID in(
Select * from dbo.F_SplitAsIntTable('1,123,234,456'))

Function defined as

CREATE FUNCTION F_SplitAsIntTable 
(
@txt varchar(max)
)
RETURNS 
@tab TABLE 
(
 ID int
)
AS
BEGIN
    declare @i int
    declare @s varchar(20)
    Set @i = CHARINDEX(',',@txt)
    While @i>1
        begin
          set @s = LEFT(@txt,@i-1)
          insert into @tab (id) values (@s)
          Set @txt=RIGHT(@txt,Len(@txt)-@i)
          Set @i = CHARINDEX(',',@txt)
        end
    insert into @tab (id) values (@txt) 
    RETURN 
END
GO
