end testpackage; / --创建过程 create or replace procedure fenye ( tableName in varchar2, --表名 fields in varchar2, --查询解果显示字段 wherecase in varchar2, --查询条件 pageSize in number, --一页显示记录数 pageNow in number, --当前页 orderField varchar2, --排序字段，为空表示不排序 orderFlag number, --排序标识 0：正序 1：倒序 myrows out number, --总记录数 myPageCount out number, --总分页 p_cursor out testpackage.test_cursor --返回的记录集 ) is --定义部分 --定义sql语句字符串 v_sql varchar2(1000); --定义两个整数 v_begin number:=(pageNow-1)*pagesize+1; --开始记录 v_end number:=pageNow*pageSize; --结束记录 --排序sql v_orderSql varchar2(100):=''; v_wherecase varchar2(100):=''; begin --执行部分 --如果orderField不为空，则进行排序，如果orderFlag=0为升序，1为降序 if orderField is not null then if orderFlag=0 then v_orderSql:=' order by '||orderField; elsif orderFlag=1 then v_orderSql:=' order by '||orderField||' desc'; else null; end if; end if; --条件判断语句 if wherecase is not null then v_wherecase:=' where '||wherecase; end if; v_sql:='select * from (select t1.* ,rownum rn from(select '|| fields ||' from '|| tableName|| v_wherecase ||' '||v_orderSql ||') t1 where rownum<='|| v_end ||') where rn>='|| v_begin; --把游标和sql关联 open p_cursor for v_sql; --计算myrows和myPageCount --组织一个sql v_sql:='select count(*) from '|| tableName || v_wherecase || ' ' ||v_orderSql; --执行sql,并把返回的值赋给myrows; execute immediate v_sql into myrows; --计算myPageCount if mod(myrows,Pagesize)=0 then myPageCount:=myrows/Pagesize; else myPageCount:=myrows/pagesize+1; end if; --关闭游标 --close p_cursor; end; / 2、.net中的oracle过程调用类 /// <summary> /// c#调用oracle的过程进行分页/// </summary> public class Paging { private string _connectionString;
