select * from 总表 where recn()<=100 into curs aaa readwrite
* 修改AAA表
select * from aaa union all select * from 总表 where recn()>100 into cursor 总表 readwrite
别客气。
对AAA表:
增加可以 insert into aaa,或者 append blank/replace 。。。
删除可以对某些特定字段(如ID)赋特殊值(如空或其他不可能的值如XXX ),然后
select * from aaa where 特定字段#'XXX' union all select * from 总表 where recn()>100 into cursor 总表 readwrite
