ORACLE分页查询SQL语句

Posted 2023-03-17

参考技术A

SELECT * FROM (SELECT t. ,ROWNUM r FROM TABLE t WHERE ROWNUM <= page pageSize) WHERE r >= （(page - 1) * pageSize + 1）

SELECT * FROM (SELECT t. ,ROWNUM r FROM TABLE t ) WHERE r BETWEEN （(page - 1) * pageSize + 1） AND (page pageSize)

Oracle, SQL Server, My SQL如何实现数据分页查询语句

参考技术A Oracle, SQL Server 和MySQL的分页SQL语句如下：Oracle：方法一：SELECT * FROM(SELECT A.*, ROWNUM RNFROM (SELECT * FROM TABLE_NAME) AWHERE ROWNUM <= 40)WHERE RN = 21；方法二：SELECT * FROM(SELECT A.*, ROWNUM RNFROM (SELECT * FROM TABLE_NAME) A)WHERE RN between 21 and 40公认第二种方法效率没有第一种高。原因是第二种要把子查询执行完，而第一种方法子查询执行到Rownum=40后就结束了。MySQL:SELECT * FROM TABLE_NAME LIMIT 10, 20表示从第11条数据开始取20条数据返回，limit后的2个参数含义为：起点和步长，即从那条数据开始，取多少条数据，再如取前20条数据：SELECT * FROM TABLE_NAME LIMIT 0, 20SQL Server2000：SELECT TOP @pagesize * FROM TABLE_NAME WHERE id not in (SELECT TOP @pagesize*(@page-1) id FROM TABLE_NAME ORDER BY id) ORDER BY id本回答被提问者采纳
