关于内存表,大神指点迷津
[code=delphi]rnrn业务中有一个循环要遍历整个数据表 , 表中有数据50万左右 , 逻辑如下 :rnrn sql := 'select * from db order by id asc'rnquery1.close;rnquery1.open(sql);rnrnwhile not query1.Eof dornbeginrn data1 := query1.FieldByName('data1').AsString;rn sql := 'select xxx from db where xxxxxx'rn query2.close;rn query2.open(sql);rn if query2.RecordCount > xxx thenrn beginrn while not query2.Eof dorn beginrn xxx := query2.FieldByName('xx').AsString;rn xxx := query2.FieldByName('xx').AsString;rn .. ..rn end;rn end;rnrn sql := 'select xxxxxx from db where xxxxxxxxx'rn query2.close;rn query2.open(sql);rn if query2.RecordCount > xxx thenrn beginrn while not query2.Eof dorn beginrn xxx := query2.FieldByName('xx').AsString;rn xxx := query2.FieldByName('xx').AsString;rn .. ..rn end;rn end;rnrn query1.next;rnend;rnrn也就是这个50万的循环中还有多个query.close / open 这样速度非常慢 ,rn 字段该设索引的也都设了 , 计算一遍用了5个小时 。 。 。 。rnrn 我现在尝试使用TFDMemTable , 以前没接触过内存表 , 我是这样用的 :rnrn sql := 'select * from db order by id asc'rnquery1.close;rnquery1.open(sql);rnquery1.FetchAll;rnFDMemTable1.close;rnFDMemTable1.data := query1.data;rnrnwhile not query1.Eof dornbeginrn data1 := query1.FieldByName('data1').AsString;rn FDMemTable1.Filtered := False;rn FDMemTable1.Filter := 'xxxxx';rn FDMemTable1.Filtered := True;rn if FDMemTable1.RecordCount > xxx thenrn beginrn for I := 1 to 20 dorn beginrn xxx := FDMemTable1.FieldByName('xx').AsString;rn xxx := FDMemTable1.FieldByName('xx').AsString;rn .. ..rn end;rn end;rnrn FDMemTable1.Filtered := False;rn FDMemTable1.Filter := 'xxxxx';rn FDMemTable1.Filtered := True;rn if FDMemTable1.RecordCount > xxx thenrn beginrn for I := 1 to 20 dorn beginrn xxx := FDMemTable1.FieldByName('xx').AsString;rn xxx := FDMemTable1.FieldByName('xx').AsString;rn .. ..rn end;rn end;rnrn query1.next;rnend;rnrn结果这样用了FDMemTable后,感觉还是很慢。。。。rn我用的不对吗?该怎么使用FDMemTable 内存表呢?rn我这样的业务需球该怎么提高运算速度呢???rnrn<em>大神</em>啊<em>大神</em>啊<em>大神</em>啊救救我吧rnrn[/code]

多线程处理图像问题,大神指点迷津!!
下面代码是处理图片的代码,大致是通过定位图片中直线坐标,再经过坐标变换<em>求</em>出相对坐标中的涂黑点,然后将涂黑点保存到数据库中,不用线程时,执行该过程一切正常,读取的结果和实际吻合,说明读取正确,因为要处理大量图片,执行时间长,是屏幕锁死会锁死很久。这个应该正常。rn现在为了提高处理速度。改为多线程后。线程中rnprocedure TGetDataThd.Execute;rn方法用 synchronize(doreadsp); 去执行发现屏幕依旧锁死,读取结果也是正确的。rnprocedure TGetDataThd.Execute;rn改用 doreadsp; 去执行屏幕不锁死了,但是读取结果不正确。rn依然用 synchronize(doreadsp); 去执行。同时开5个线程去运行,屏幕锁死,5顺序顺序执行,并没有达到5个线程并行运行从而提高处理速度的预期效果。rn例如有100个图片,每20个图片分一组,分别开5个线程运行,运行时间是20个图片处理时间*5而非预期的运行时间减少为1/5rn。查了一些资料和翻了很多遍csdn以前的帖子都找不到答案,<em>求</em><em>大神</em><em>指点迷津</em>啊。rnrn下面是主要处理图片的代码,可能一些算法需要优化,现在顾不上了,只<em>求</em>能搞定多线程处理图片的问题。rnrnprocedure TGetDataThd.DoReadSp;rnconstrn MCW_EM = DWord($133f);rnvarrn i,j,ret,iztscore,icontentscore,iLineCount:integer;rn bTempb,testbmp:Tbitmap;rn sCheckInfo,model_cls:string;rn strBarcode : String;rn DecodePara : PTDECODEPARASTRUCT;rn BarCodeInfo : PTTOTALBARCODEINFOSTRUCT;rn pInfo: pPTBARCODEINFOSTRUCT;rn modelid,checkid,cadreid,cadreidlist,zt_pose_count,cadre_pose_count,content_pose_count,use_opinion_flag,zt_pose,content_pose:string;rn overall_flag,content_line_direction,card_rowcount,card_colcount:string;rn zt_posetmp,content_posetmp,zt_Score,content_score:string;rn //原点和斜率定义rn iX,iY,iPoseArray,iPose:integer;rn AX,AY,BX,BY,CX,CY,AX0,AY0,BX0,BY0,CX0,CY0,DX0,DY0,ox,oy,LPose:integer;rn posestates:string;rn BlackFound:boolean;rn fK:real;rn scheckmodel:string;rn sSorPath,sDitPath,deptid:string;rn bfound:boolean;rn adoquery1,ADOQuery2:Tadoquery;rnbeginrn //search the whole imagern Set8087CW(MCW_EM);rn j:=iStart;rn if iList=1 thenrn beginrn CardDistinNewForm.ProgressBar1.Visible:=true;rn CardDistinNewForm.ProgressBar1.Progress:=1;rn CardDistinNewForm.ProgressBar1.MaxValue:=iEnd-iStart+1;rn end;rn if iList=2 thenrn beginrn CardDistinNewForm.ProgressBar2.Visible:=true;rn CardDistinNewForm.ProgressBar2.Progress:=1;rn CardDistinNewForm.ProgressBar2.MaxValue:=iEnd-iStart+1;rn end;rn if iList=3 thenrn beginrn CardDistinNewForm.ProgressBar3.Visible:=true;rn CardDistinNewForm.ProgressBar3.Progress:=1;rn CardDistinNewForm.ProgressBar3.MaxValue:=iEnd-iStart+1;rn end;rn if iList=4 thenrn beginrn CardDistinNewForm.ProgressBar4.Visible:=true;rn CardDistinNewForm.ProgressBar4.Progress:=1;rn CardDistinNewForm.ProgressBar4.MaxValue:=iEnd-iStart+1;rn end;rn tryrn adoquery1:=Tadoquery.Create(nil);rn adoquery2:=Tadoquery.Create(nil);rn adoquery1.Connection:=DataConnDataModel.ADOConn;rn adoquery2.Connection:=DataConnDataModel.ADOConn;rn while J15 thenrn beginrn iPose:=iPose+1;rn if iPose=1 thenrn beginrn AX0:=round((AX+BX)/2+0.1);rn AY0:=round((AY+BY)/2+0.1);rn end;rn if iPose>1 thenrn beginrn BX0:=round((AX+BX)/2+0.1);rn BY0:=round((AY+BY)/2+0.1);rn end;rn end;rn endrn elsern beginrn posestates:='0';rn LPose:=0;rn end;rn endrn elsern beginrn posestates:='0';rn LPose:=0;rn end;rn iX:=iX+1;rn end;rn ix:=145;rn iy:=139;rnrn

缩略图生成策略 - 大神指点迷津,急~~~~
最近在做一个在线商城后端开发的项目,涉及到要将商家上传的图片在手机,桌面客户端及web页面上显示。针对不同的终端,需对应生成相应尺寸的缩略图以适应终端展示的需<em>求</em>(比如:手机150*150,web255*200),此时,我想到的解决方案如下:rnrn方案一:在商家上传图片时就生成三种尺寸的缩略图存储在服务器中,当终端请<em>求</em>图片时,根据终端<em>类型</em>返回对应的图片。rn方案二:在终端请<em>求</em>图片时,根据请<em>求</em>参数中传递的所需图片的尺寸,实时生成缩略图返回。rnrn之前没做过这块,烦请哪位<em>大神</em>指点一下,到底以上两种方案那个更适合?或者有更加合理的方案呢?rn谢谢了~~~~rn

高人给我指点迷津
小弟我是学文科专业的,在大三上学期接触到的Java,特别喜欢这门语言,之后就一直在自学(因为培训太贵,没有那么多钱),都是看书,看网上下的视频,文档,论坛,别人的博客,就这样一直学下来的,期间做过几个项目(博客,商城,DRP,OA),其中OA是看的尚学堂的视频,学习了工作流,但也没有按故就搬写代码,也是加入了一些自己的思想的。现在大四,面临找工作了,前些天在网上投了7,8份简历,可是连个信儿也没有,都石沉大海了,心里挺急的,我是沈阳的,网站上沈阳招聘Java程序员也就那么10多个,我现在特渴望给我个笔试或者面试的机会(做梦都想)。在这里<em>求</em>高人给我<em>指点迷津</em>,是继续投简历,还是再学习一下什么知识补充一下自己(当然Java的学习是无止境的,我是指当前再学写什么,更能增加面试的机会,因为现在连面试都没有过,55555......)。rnrn这是我简历写的技能(或多或少有些水分,但是我也不能写熟悉Java啊,那还是Java程序员嘛)rnrn精通Core Java,Servlet,JSP;rn熟练掌握各种常用编程语言:Java、JSP、Javascript、XML、html;rn精通基于Web应用的Java编程:JavaBeans,JSP/Servlet;rn能熟练使用Struts、Struts2、Hibernate、Spring等开源框架;rn熟悉DWR、Jquery等Ajax框架;rn熟悉jBPM工作流引擎;rn能熟练使用Java web服务器,及应用服务器进行Java程序开发:例如Tomcat,WebLogic;rn熟练使用MySql、Oracle(9i)数据库;rn能够熟练使用Eclipse开发工具。rn
