支持Oracle的列表控件分页使用的SQL

     这段时间，公司有个新项目其数据库使用Oracle，对原先支持SQL Server数据源的列表控件进行了调整，现把分页使用的静态SQL语句提供如下：

 

--按code,num列正序排列的1-15条数据 第1页
   
SELECT code,num,title,contents,remark,snum FROM
(
    SELECT ROWNUM QDZHBSH_RECNO,code,num,title,contents,remark,snum FROM
    (SELECT code,num,title,contents,remark,snum FROM sys_code ORDER BY code,num asc)
    WHERE ROWNUM <= (1 + 15 - 1)
    ORDER BY ROWNUM ASC
)
WHERE QDZHBSH_RECNO BETWEEN 1 AND (1 + 15 - 1)
   
--按code,num列正序排列的16-30条数据 第2页
   
SELECT code,num,title,contents,remark,snum FROM
(
       SELECT ROWNUM QDZHBSH_RECNO, code,num,title,contents,remark,snum FROM
      (SELECT code,num,title,contents,remark,snum FROM sys_code ORDER BY code,num asc)
      WHERE ROWNUM <= (16 + 15 - 1)
      ORDER BY ROWNUM ASC
)
WHERE QDZHBSH_RECNO BETWEEN 16 AND (16 + 15 - 1)    
   

--按code,num列正序排列的31-45条数据 第3页
   
SELECT code,num,title,contents,remark,snum FROM
(
       SELECT ROWNUM QDZHBSH_RECNO, code,num,title,contents,remark,snum FROM
      (SELECT code,num,title,contents,remark,snum FROM sys_code ORDER BY code,num asc)
      WHERE ROWNUM <= (31 + 15 - 1)
      ORDER BY ROWNUM ASC
)
WHERE QDZHBSH_RECNO BETWEEN 31 AND (31 + 15 - 1)
