(SELECT ROW_NUMBER() OVER(ORDER BY RecordId) AS RowID,* FROM BaseUser
) as table1
WHERE RowID BETWEEN 20 AND 30
-- RowID 将SELECT ROW_NUMBER() OVER(ORDER BY RecordId) 查出的结果取个别名,用于取结果记录的条件[即: RowID BETWEEN 20 AND 30]
--table1 相当于 SELECT ROW_NUMBER() OVER(ORDER BY RecordId) AS RowID,* FROM BaseUser 查出来的结果当成一个临时表
