在oracle中限制返回结果集的大小,类似于mysql的limit(转译)-数据库相关-PHP教程-
Oracle不支持类似于 MySQL 中的 limit. 但你还是可以rownum来限制返回的结果集的行数.
如果你只希望返回前十行纪录,你可以这样写:
SELECT * FROM table WHERE ROWNUM但是下面的语句是不对的:
SELECT * FROM table WHERE ROWNUM>90 AND ROWNUM这是因为 Oracle 认为这个条件不成立,所以没有返回。
你应该这样写:
SELECT * FROM table WHERE ROWNUMminus
SELECT * FROM table WHERE ROWNUM
