method one:
Select * from ??????? (SELECT ROWNUM AS MY_ROWNUM, A. * from? My_TABLE? WHERE ROWNUM <20000) Where my_rownum> = 10000
Method Two:
Select * from my_tablewhere rownum <= 20000 minus (select * from my_table where rownum <10000)
In contrast, the method has a high efficiency.
Method 1 Improvement:
Remove my_rownum field
Select C. * from ??????? (SELECT ROWNUM AS MY_ROWNUM, A. * from? my_table? a? WHERE ROWNUM <20000) B, MY_TABLE? C Where my_rownum> = 15000 and C.ID = B.ID ;
