Using derived tables you can combine both selects into one

select * from (select * From Master where ID < lcPreviousID UNION ALL
select * from Archive where ID < lcPreviousID order by ID Desc)
UNION ALL
select * from (select * From Master where ID > lcPreviousID UNION ALL
select * from Archive where ID > lcPreviousID order by ID ASC)

But what result do you want to achieve with this query - get all records except for current record?
