SQL存儲過程代碼：

 

CREATE proc page ( @table_name varchar(100),--表名 @count int,--每頁顯示好多行 @page int,--當前頁數 @table_id varchar(100),--表的主鍵 @sqlWhere varchar(1000),--過濾條件 @sqlOrder varchar(1000),--排序條件 @sumCount int output--返回參數，返回總頁數 ) as declare @sqlScript nvarchar(4000) select @sumCount = 0 if @sqlWhere is not null and @sqlWhere <> '' begin select @sqlScript = 'select @sumCount=count(*) from '+@table_name + ' where ' + @sqlWhere end else begin select @sqlScript = 'select @sumCount=count(*) from '+@table_name end execute sp_executesql @sqlScript,N'@sumCount int output',@sumCount output--得到總行數 --select @sumCount if @sumCount%@count<>0 select @sumCount = @sumCount / @count + 1--得到總頁數 else select @sumCount = @sumCount / @count select @page = @page * @count--過濾的行數 select @sqlScript = 'select top '+cast(@count as varchar)+' * from ' + @table_name + ' where ' + @table_id + ' not in (select top ' + cast(@page as varchar) + ' ' +@table_id+ ' from '+@table_name+' '+case when @sqlWhere is not null and @sqlWhere<>'' then ' where ' +@sqlWhere else '' end+isnull(@sqlOrder,'')+' ) ' + case when @sqlWhere is not null and @sqlWhere<>'' then ' and ' + @sqlWhere else '' end+isnull(@sqlOrder,'') exec(@sqlScript) GO

 

調用存儲過程方法：

//獲得某城市下，滿足貢獻度需求的迷宮任務列表

 

public ArrayList getMiGongRenWuList(String table_name,int count,int page,String table_id,String sqlWhere,int []out_print){ ArrayList migong_list = new ArrayList(); Connection con = null; try { con = dbMain.getConnection(); con.setAutoCommit(false); CallableStatement cstm = con.prepareCall( "{call page(?,?,?,?,?,?,?)}"); cstm.setString(1,table_name); cstm.setInt(2,count); cstm.setInt(3,page); cstm.setString(4,table_id); cstm.setString(5,sqlWhere); cstm.setString(6,""); cstm.registerOutParameter(7,Types.INTEGER); ResultSet rs = cstm.executeQuery(); while(rs.next()){ migong_list.add(City_MiGongDAO.assembleCity_MiGong(rs)); } out_print[0] = Integer.parseInt(cstm.getObject(7).toString()); con.commit(); con.close(); } catch (ClassNotFoundException e) { e.printStackTrace(); } catch (SQLException e) { try { con.rollback(); con.close(); } catch (SQLException e1) { e1.printStackTrace(); } e.printStackTrace(); } return migong_list; }

 

SEVLET調用該方法：

int []out_page = {0}; ArrayList city_renwu_list = RenWu_MiGongDao.getMiGongRenWuList(table_name,16,page,table_id,sqlWhere,out_page);
