oracle写脚本实现分页操作

SELECT /*+ FIRST_ROWS ORDERED USE_NL(X,Y) */

Y.*

FROM   (SELECT RID

FROM   (SELECT /*+ FIRST_ROWS */ T.ROWID RID,ROWNUM RN

FROM   TABLE_NAME T

WHERE  ROWNUM<=5)

WHERE  RN>=3) X,

TABLE_NAME Y

WHERE X.RID=Y.ROWID;

无分页要求的也可以这样,看是什么情况了

一般来说分页语句不可能会翻页到很后面的，越到后面越慢

SELECT FIELD1,FIELD2,FIELD3

FROM   (SELECT /*+ FIRST_ROWS */

T.FIELD1,T.FIELD2,T.FIELD3,ROWNUM RN

FROM   TABLE_NAME T

WHERE  ROWNUM<=5)

WHERE  RN>=3
