oracle儲存過程實現分頁

建立儲存過程：

--建立存放游標的包--

create or replace package page_package
is  --申明游標--
type page_cursor is ref cursor;
end page_package;
--建立查詢所有使用者的過程--
create or replace procedure proc_getalluser(users out page_package.page_cursor)
asbegin
open users for
select * from tuser;
end;
--建立分頁儲存過程--
create or replace procedure proc_page(
tablename in varchar2,--需要查詢的表名--
pagenum in number,--查詢頁碼--
pagesize in number,--每頁條數--
term in varchar,--查詢條件，形如： and name = ? and ......--
datas out page_package.page_cursor,--查詢出來的資料--
maxpagenum out number --最大頁碼--
)is--定義需要執行的sql語句的變數--
v_sql varchar2(1000);
--定義兩個整數變數--
v_begin number:=(pagenum-1)*pagesize+1;
v_end number:=pagenum*pagesize;
--定義最大條數的變數--
v_count number:=0;
begin
--給v_sql賦值--
v_sql := 'select p.* from(select t.*,rownum rn from '||tablename||' t where 1=1 '||term||') p where p.rn between '||v_begin||' and '||v_end;
--執行sql給游標賦值--
open datas for v_sql;
--計算最大頁碼--
v_sql := 'select count(*) from '||tablename||' where 1=1 '||term;
execute immediate v_sql into v_count;
if mod(v_count,pagesize)=0 then
maxpagenum := v_count/pagesize;
else
maxpagenum := v_count/pagesize+1;
end if;
end;

分頁sql：

--分頁的sql--

select p.* from
(select t.*,rownum rn from torganization t) p where p.rn between 2 and 4

使用：

private resultset rs;

private callablestatement cst;
string sql = "";
try 
} catch (exception e) finally
