各种数据库的分页查询语句

转自：http://www.2cto.com/database/201311/255641.html

1.oracle数据库分页

select * from (select a.*,rownum rc from 表名 where rownum<=endrow) a where a.rc>=startrow

 

2.DB2数据库分页

Select * from (select rownumber() over() as rc,a.* from (select * from 表名 order by 列名) as a) where rc between startrow and endrow

 

3.SQL Server 2000数据库分页

Select top pagesize * from 表名 where 列名 not  in(select top pagesize*page 列名 from  表名 order by 列名) order by 列名

 

4.SQL Server 2005数据库分页

Select * from (select 列名,row_搜索number() over(order by  列名1) as 别名from 表名) as t where t.列名1>=startrow and t.列名1<=endrow

 

5.MySQL数据库分页

Select * from 表名 limit startrow,pagesize

(Pagesize为每页显示的记录条数)

 

6.PostgreSQL数据库分页

Select * from 表名 limit pagesize,offset startrow

(Pagesize为每页显示的记录条数.)

 

 7.通用模式select * from (

 select * from tb_student where sid not in(

     select sid from tb_student where rownum<=(currentPage-1)*pageSize)

) where rownum <=pageSize;

项目实战：

Oracle 

StringBuffer tmpBuffer = new StringBuffer();
tmpBuffer.append("SELECT * FROM (SELECT originTable.*, ROWNUM ");
tmpBuffer.append(ROWNUMFIELD);
tmpBuffer.append(" FROM (");
tmpBuffer.append(originalSql);
tmpBuffer.append(")");
tmpBuffer.append(" originTable ");

//syp 屏蔽，解决翻页数据错误的问题
/*if (iEnd <= totalRows) {
tmpBuffer.append(" WHERE ROWNUM<");
tmpBuffer.append(Integer.toString(iEnd));
}*/

tmpBuffer.append(") WHERE ");
tmpBuffer.append(ROWNUMFIELD);
tmpBuffer.append(">=");
tmpBuffer.append(Integer.toString(iBegin));
if (iEnd <= totalRows) {
tmpBuffer.append(" and ");
tmpBuffer.append(ROWNUMFIELD);
tmpBuffer.append("<");
tmpBuffer.append(Integer.toString(iEnd));
}

originalSql = tmpBuffer.toString();
Mysql

/**
* 实现mysql的分页查询的语句
* @param originalSql
* @param rowCountPerPage
* @param totalRows
* @param page
* @return
*/
public static String parsePageMysqlSQL(String originalSql, int rowCountPerPage,int totalRows, int page) {
int iBegin = 0;
int pageCount = 0;

if (rowCountPerPage > 0 && totalRows > rowCountPerPage) {
if (totalRows % rowCountPerPage == 0)
pageCount = totalRows / rowCountPerPage;
else
pageCount = totalRows / rowCountPerPage + 1;

if (page < 1)
page = 1;
if (page > pageCount) {
page = pageCount;
}
iBegin = (page - 1) * rowCountPerPage ;

StringBuffer tmpBuffer = new StringBuffer();
tmpBuffer.append("SELECT originTable.* ");
tmpBuffer.append(" FROM (");
tmpBuffer.append(originalSql);
tmpBuffer.append(")");
tmpBuffer.append(" originTable ");
tmpBuffer.append("limit ");
tmpBuffer.append(Integer.toString(iBegin));
tmpBuffer.append(",");
tmpBuffer.append(rowCountPerPage);

originalSql = tmpBuffer.toString();
}
return originalSql;
}
