2007年1月2日

有人问这样的sql该怎么实现：
表数据和结构
   CODE NAME    B01    S01    B02    S02
    1          张三       数学    80
    1          张三                            语文    75
    2          王五       数学    70
    2          王五
    3          李四       数学    50
    3          李四                           语文    88

希望查询出如下结果：
   CODE SUM_STR(NAME)    B01    SUM_STR(S01)    B02    SUM_STR(S02)
    1                张三                    数学                80           语文            75
    2                王五                    数学                70
    3                李四                    数学                50           语文             88
这个问题可以采用自定义的聚集函数来实现：

create or replace type strcat_type as object (

cat_string varchar2 ( 4000 ),

static function ODCIAggregateInitialize(cs_ctx In Out strcat_type) return number ,

member function ODCIAggregateIterate(self In Out strcat_type,value in varchar2 ) return

number ,

member function ODCIAggregateMerge(self In Out strcat_type,ctx2 In Out strcat_type)

return number ,

member function ODCIAggregateTerminate(self In Out strcat_type,returnValue Out

varchar2 ,flags in number ) return number

)

------------------------------------

create or replace type body strcat_type is

static function ODCIAggregateInitialize(cs_ctx IN OUT strcat_type) return number

begin

cs_ctx : = strcat_type( null );

return ODCIConst.Success;

end ;

member function ODCIAggregateIterate(self IN OUT strcat_type,

value IN varchar2 )

return number

begin

if self.cat_string is null then

self.cat_string : = value;

end if ;

return ODCIConst.Success;

end ;

member function ODCIAggregateTerminate(self IN Out strcat_type,

returnValue OUT varchar2 ,

flags IN number )

return number

begin

returnValue : = self.cat_string;

return ODCIConst.Success;

end ;

member function ODCIAggregateMerge(self IN OUT strcat_type,

ctx2 IN Out strcat_type)

return number

begin

       if self.cat_string is null then
                   self.cat_string := ctx2.cat_string;
          end if;

return ODCIConst.Success;

end ;

-------------------

CREATE OR REPLACE FUNCTION sum_str(input varchar2 )

RETURN varchar2

PARALLEL_ENABLE AGGREGATE USING strcat_type;

-------最后查询语句：

select code,sum_str(name), sum_str(b01) b01,sum_str(s01) ,sum_str(b02) b02,sum_str(s02)

from javaeye group by code order by code

openlayers如何利用vector和style作出marker

定义标注的样式，这个决定标注显示的方式，必须定义好
1 $package("com.bct.map");
2 com.bct.map.EncoderMarkerStyle = {
3     'bigEncoder':{
4         graphicWidth:24,
5         graphicHeight : 24,
6         graphicXOffset : -12,
7         graphicYOffset : -24,
8         externalGraphic : "scripts/map/img/channel2.png"
9     },
10     'smallEncoder':{
11         graphicWidth:16,
12         graphicHeight : 16,
13         graphicXOffset : -8,
14         graphicYOffset : -16,
15         externalGraphic : "scripts/map/img/channel.gif"
16     },
17     'selectStyle':{
18         pointerEvents: "visiblePainted",
19         border:"border:25 outset #ff88ff",
20         cursor: "pointer",
21         graphicWidth:24,
22         graphicHeight : 24,
23         graphicXOffset : -12,
24         graphicYOffset : -24,
25         externalGraphic : "scripts/map/img/channel2.png"
26     },
27     styleMap: new OpenLayers.StyleMap({
28                     "select": new OpenLayers.Style({pointRadius: 24})
29     })
30 }

marker层，扩展vector层，通过point和style达到marker的效果

1 $package("com.bct.map");
 2 $import("com.bct.map.EncoderMarkerStyle");

一次sql调优历程

在项目进入性能测试阶段，终于爆发了sql运行缓慢，系统吞吐量下降，甚至一度出现oracle服务器cpu100%的情况。具体开发和测试人员报告情况，开始介入处理。

具体查找性能缓慢的过程略除。
发现一条sql运行缓慢。通过跟踪发现一下信息
select alias_p2.pendingid, alias_p2.workitemid, alias_p2.operationid, alias_p2.operationkey,

2 alias_p2.title, alias_p2.sendercn, alias_p2.operatedes, alias_p2.pendingstate,

3 alias_p2.parameter, alias_p2.createdate, alias_p2.deptname, alias_p2.completeddate ,

4 alias_p2.openstate , alias_p2.name, alias_p2.processinstanceid, alias_p2.asset

5 from ( select alias_p1.pendingid, alias_p1.workitemid, alias_p1.operationid,

6 alias_p1.operationkey, alias_p1.title, alias_p1.sendercn, alias_p1.operatedes,

7 alias_p1.pendingstate, alias_p1.parameter, alias_p1.createdate, alias_p1.deptname,

8 alias_p1.completeddate , alias_p1.openstate , alias_p1.name, alias_p1.processinstanceid ,

9 alias_p1.asset , rownum rn from(select alias_p.pendingid, alias_p.workitemid, alias_p.operationid,

10 alias_p.operationkey, alias_p.title, alias_p.sendercn, alias_p.operatedes, alias_p.pendingstate,

11 alias_p.parameter, alias_p.createdate, alias_p.deptname, alias_p.completeddate , alias_p.openstate ,

15 and (alias_p.deptname=' 审控部信息处 ' or alias_p.deptname='' or alias_p.deptname is null)

16 and w.workitemid = alias_p.workitemid and pi.processinstanceid = w.processinstanceid

17 and pi.completeddate is null and pd.processdefinitionid = w.processdefinitionid order by alias_p.createdate desc) alias_p1 where rownum <=10)

其中一致读达到近3万次，关联调用出现314次。排序数值也非常多，显然第一目标是把这两个数据降下来。
通过进一步的分析。发现出现这些问题的主要原因是调用eam_db.concatassetname( alias_p.operationkey, alias_p.operationid )这个包。
开始考虑直接在sql外层做关联，不用function来实现。利用聚集函数来合并数据。
着手建立：

聚集函数： CREATE OR REPLACE FUNCTION F_ASSETLINK(P_STR VARCHAR2) RETURN VARCHAR2
AGGREGATE USING asset_link;

----------------------
创建type：CREATE OR REPLACE TYPE ASSET_LINK AS OBJECT (
STR VARCHAR2(30000),
STATIC FUNCTION ODCIAGGREGATEINITIALIZE(SCTX IN OUT ASSET_LINK) RETURN NUMBER,
MEMBER FUNCTION ODCIAGGREGATEITERATE(SELF IN OUT ASSET_LINK, VALUE IN VARCHAR2) RETURN NUMBER,
MEMBER FUNCTION ODCIAGGREGATETERMINATE(SELF IN ASSET_LINK, RETURNVALUE OUT VARCHAR2, FLAGS IN NUMBER) RETURN NUMBER,
MEMBER FUNCTION ODCIAGGREGATEMERGE(SELF IN OUT ASSET_LINK, CTX2 IN ASSET_LINK) RETURN NUMBER
)
------------------------------------------------------

创建type body：CREATE OR REPLACE TYPE BODY ASSET_LINK IS
STATIC FUNCTION ODCIAGGREGATEINITIALIZE(SCTX IN OUT ASSET_LINK) RETURN NUMBER IS
BEGIN
SCTX := ASSET_LINK(NULL);
RETURN ODCICONST.SUCCESS;
END;
MEMBER FUNCTION ODCIAGGREGATEITERATE(SELF IN OUT ASSET_LINK, VALUE IN VARCHAR2) RETURN NUMBER IS
BEGIN
SELF.STR := SELF.STR ||','|| VALUE;
RETURN ODCICONST.SUCCESS;
END;
MEMBER FUNCTION ODCIAGGREGATETERMINATE(SELF IN ASSET_LINK, RETURNVALUE OUT VARCHAR2, FLAGS IN NUMBER) RETURN NUMBER IS
BEGIN
RETURNVALUE := SELF.STR;
RETURN ODCICONST.SUCCESS;
END;
MEMBER FUNCTION ODCIAGGREGATEMERGE(SELF IN OUT ASSET_LINK, CTX2 IN ASSET_LINK) RETURN NUMBER IS
BEGIN
NULL;
RETURN ODCICONST.SUCCESS;
END;
END;
调整sql如下：

   alias_p.operationkey, alias_p.title, alias_p.sendercn, alias_p.operatedes, alias_p.pendingstate,

利用mv做跨

数据库迁移过程中需要目标数据库和原数据库结构相同和数据是最新。
为了保持最新数据和快速切换就不可以利用exp/imp的方式，利用data guard则有平台的问题。
在这种情况下，可以利用on prebuilt table选项创建mv。然后同步运行一段时间。一次切换，删除
mv，这种情况下可以保持同名的表。mv删除。达到数据同步，切换的目标。

分析函数一例

select z.a,z.b,z.c from (select lag(t.a,2)over(order by t.a) pp_val, lag(t.a,1)over(order by t.a) p_val, t.a, lead(t.a,1)over(order by t.a) n_val, lead(t.a,2)over(order by t.a) nn_val, t.b,t.c from test2 t) z where z.a = '1' and ((z.p_val = '1' and z.pp_val = '1') or (z.p_val = '1' and z.n_val = '1') or (z.n_val = '1' and z.nn_val = '1'));

夜读tom感悟

查询结果xml化： select dbms_xmlquery.getXML(' select * from test')from dual; 表的历史记录：执行：begin dbms_wm.enableversioning('tablename','VIEW_WO_OVERWRITE') 则对这个表的cud操作都会记录历史，这个在系统中做历史再好不过了。还有终于被tom说明：分析函数原来就是矩阵运算，呵呵，终于知道这类函数的数学原理了，呵呵，真爽，总算知道怎么理解了。还有宝贝儿遇到新项目，需要很深的会计知识了，还被老板乱说，导致不好工作，希望她不要烦恼，开心工作

lighttped(window)+scgi+rails配置方式

配置:server.modules
server.modules              = (
                                "mod_rewrite",
                                "mod_redirect",
                                "mod_access",
                                "mod_status",
                                "mod_scgi",
                                "mod_accesslog" )
配置
index-file.names            = ( "index.php", "index.html",
                                            "index.htm", "default.htm" )
#### accesslog module
accesslog.filename          = "c:/depot/log/access.log"
static-file.exclude-extensions = ( ".php", ".pl", ".fcgi",".scgi" )       标红的需要加上

## bind to port (default: 80)
server.port                = 8080------------------访问端口,我设置8080

## error-handler for status 404
server.error-handler-404   = "/dispatch.scgi"
-----------------------------------------------
scgi.server = ("dispatch.scgi" => ((
"host" => "127.0.0.1",
"port" => 9999,
"check-local" => "disable"
)) )

scgi.debug=3

status.status-url = "/server-status"
status.config-url = "/server-config"

-------------------------------------
## server.virtual-* options
server.document-root = "c:/depot/public"
记得这个需要设置到public目录,不然按默认的rails生成的文档一些东西访问不来的
-----------------------------------------------------------------------------------------------------
需要注意的是你开发的程序需要放在c盘下,不然找不到config/scgi.yaml这个文件
然后lighttpd必须装在c盘下(当前版本下1.4.11)
