二级域名session共享
一、实现IHttpModule类，见后。
二、修改web.config
添加域名
<appSettings><add key="RootDomain" value=""/></appSettings>
RootDomain cookie域名，若是本地则写空
by design domain names must have at least two dots otherwise browser will say they are invalid
when working on localhost (!) the cookie-domain must be set to "" or NULL or FALSE instead of "localhost"
增加过滤
<system.web>
<sessionState mode="StateServer" stateNetworkTimeout="10" timeout="120" stateConnectionString="tcpip=127.0.0.1:42424" />
<httpModules>
<add name="SessionSharedHttpModule" type="ClassLibrary.BasePage.MakeSessionIDOneOnly,ClassLibrary"/>

数据库拆分
分表方案
数据量过大或者访问压力过大的数据表需要切分
忙闲分表
单数据表字段过多，可将频繁更新的整数数据与非频繁更新的字符串数据切分 范例user表 ，个人简介，地址，QQ号，联系方式，头像 这些字段为字符串类型，更新请求少； 最后登录时间，在线时常，访问次数，信件数这些字段为整数型字段，更新频繁，可以将后面这些更新频繁的字段独立拆出一张数据表，表内容变少，索引结构变少，读写请求变快。
横向切表
等分切表，如哈希切表或其他基于对某数字取余的切表。等分切表的优点是负载很方便的分布到不同服务器；缺点是当容量继续增加时无法方便的扩容，需要重新进行数据的切分或转表。而且一些关键主键不易处理。
递增切表，比如每1kw用户开一个新表，优点是可以适应数据的自增趋势；缺点是往往新数据负载高，压力分配不平均。 日期切表，适用于日志记录式数据，优缺点等同于递增切表。 个人倾向于递增切表，具体根据应用场景决定。
奇葩的回车换行
char(9) 水平制表符 char(10) 换行，使光标下移一格 char(13) 回车。光标到行首 将下面的打印结果执行下，会发现第一个是可以执行的，但第二个报“GO”附近有语法错误” 可能sqlserver认的是换行而不是回车 PRINT 'SET ANSI_NULLS ON' + CHAR(10) + 'GO' PRINT 'SET ANSI_NULLS ON' + CHAR(13) + 'GO'
sql反模式
1，父子表的存储
- 路径枚举：一列存此关系，以‘/’分开父子ID，例：1/2/3/4,这种可无限扩展。查子结点好查，但所有父结点需要用1/2/3/4 like organid + '%',这种用不上索引的方式，效率低，不过合用于数据量小的地方，如基表。
- 闭包表：基于查询时间考虑，可采用时间换空间的方式，将所有关系一一存储，并加一列存储深度。如ancestor,descendant,length
SSB：Activation Execution Context
Exception Message: The activated proc [dbo].[storedprocedure_name] running on queue [QUEUE_NAME] output the following: 'The server principal "sa" is not able to access the database "AnotherDBName" under the current security context.' SOLUTION: The problem is that the activation execution context is trusted only in the database, not in the whole server, like other stored procedures or DB. So when the activated SP calls another SP located in the other DB, the above exception will occur. The simplest solution is to mark the database [SERVICE PROGRAM RUNNING ON IT] as trustworthy. ALTER DATABASE [DBNAME] SET TRUSTWORTHY ON 引自：【SSB】Activation Execution Context

转自一步一步实现ReportingServices2008匿名访问
在ReportingServices2005中我们需要匿名访问报表的时候，只需要在IIS里面做下简单设置就可以实现，而在ReportingServices2008(R2)中不在依靠IIS，只是占用的还是80端口而已。其实匿名访问有很多中解决办法，譬如：使用ReportViewer控件、与SharePoint集成等等……
下面我介绍SQL团队技术博客所提供的比较彻底而且通用的方法 。(注：修改配置文件前如果害怕出问题请提前备份)
第一步：编译SQL团队所提供的代码并将所生成的Microsoft.Samples.ReportingServices.AnonymousSecurity.dll文件拷贝到SQL Server的安装目录*:\Program Files\Microsoft SQL Server\MSRS10_50.MSSQLSERVER\Reporting Services\ReportServer\bin下
第二步：修改Reporting Services\ReportServer 和Reporting Services\ReportManager文件中的web.config文件，替换二者中的节点，将
-
<authentication mode="Windows" /> - <identity impersonate="true"/>
替换为
-
<authentication mode="None" /> - <identity impersonate="false"/>
第三步：修改Reporting Services\ReportServer修改rereportserver.config把
-
<Authentication> - <AuthenticationTypes>
- <RSWindowsNegotiate/>
- <RSWindowsNTLM/>
- </AuthenticationTypes>
- <EnableAuthPersistence>true</EnableAuthPersistence>
- </Authentication>
修改为
-
<Authentication> - <AuthenticationTypes>
- <Custom/>
- </AuthenticationTypes>
- <EnableAuthPersistence>true</EnableAuthPersistence>
- </Authentication>
第四步：修改Reporting Services\ReportServer修改rereportserver.config在
-
<Security> - <Extension Name="Windows" Type="Microsoft.ReportingServices.Authorization.WindowsAuthorization, Microsoft.ReportingServices.Authorization"/>
- </Security>
- <Authentication>
- <Extension Name="Windows" Type="Microsoft.ReportingServices.Authentication.WindowsAuthentication, Microsoft.ReportingServices.Authorization"/>
- </Authentication>
节点下，添加
-
<Security> - <Extension Name="None" Type="Microsoft.Samples.ReportingServices.AnonymousSecurity.Authorization, Microsoft.Samples.ReportingServices.AnonymousSecurity" />
- </Security>
- <Authentication>
- <Extension Name="None" Type="Microsoft.Samples.ReportingServices.AnonymousSecurity.AuthenticationExtension, Microsoft.Samples.ReportingServices.AnonymousSecurity" />
- </Authentication>
到此为止，ReportingServices2008(R2)的匿名访问就大功告成了。

存储过程间传值
-- First Stored Procedure CREATE PROCEDURE SquareSP @MyFirstParam INT AS DECLARE @MyFirstParamSquare INT SELECT @MyFirstParamSquare = @MyFirstParam*@MyFirstParam -- Additional Code RETURN (@MyFirstParamSquare) GO Now let us create second Stored Procedure which gives us area of the circle. -- Second Stored Procedure CREATE PROCEDURE FindArea @SquaredParam INT AS DECLARE @AreaofCircle FLOAT SELECT @AreaofCircle = @SquaredParam * PI() RETURN (@AreaofCircle) GO You can clearly see that we need to pass the result of the first stored procedure (SquareSP) to second stored procedure (FindArea). We can do that by using following method: -- Pass One Stored Procedure's Result as Another Stored Procedure's Parameter DECLARE @ParamtoPass INT, @CircleArea FLOAT -- First SP EXEC @ParamtoPass = SquareSP 5 -- Second SP EXEC @CircleArea = FindArea @ParamtoPass SELECT @CircleArea FinalArea GO You can see that it is extremely simple to pass the result of the first stored procedure to second procedure. You can clean up the code by running the following code. -- Clean up DROP PROCEDURE SquareSP DROP PROCEDURE FindArea GO
sqlserver与地图
sqlserver提供两种类型geometry(平面几何),geography(球面)用来存储地图数据。
有人用此竟画出了图形，效果见下图，sql
SQLServer2008 R2 Reporting Services报表服务
1,报表生成器：report builder:提供不具程序基础的使用者通过简易图形化开发界面就能达到数据查询与报表的建立。
2，BIDS：目标是专业的开发人员。
3，数据区域：
- 数据表：以表格方式来呈现固定栏数的数据，想像数据库中的table.列固定。
- 矩阵：行或阵可动态产生。
- 列表：可将字段设置到任意位置。
- 图表：以图形化的方式呈现汇总后的数据
- 仪表：以量测计的方式来显示汇总数值相对大小
- 地图：以地理信息的方式标示数值
4，共享数据源：一个报表可一个数据源（内嵌数据源），也可多个报表一个数据源，即共享数据源。
5，报表结构：页眉，页脚，主体及数据。
6，Tablix:数据表(table)+矩阵(matrix),在报表上放置数据源后，就会出现。
7,行组：可认为sql中的group。
- 父组，子组：group 父，子 先按父汇总，再按子汇总
- 相邻：在当前行显示完数据后，再显示多行数据。用此属性可在一张报表上显示两张报表。比如前面按部门显示业绩，显示完之后，下面开始按年显示汇总的业绩。
8，数据显示格式，在字段的format属性中修改，对应的有：
引自BOL
下表列出了常见的 .NET Framework 数字格式设置字符串。
| 格式字符串 | 名称 |
|---|---|
|
C 或 c |
货币 |
|
D 或 d |
十进制 |
|
E 或 e |
科学型 |
|
F 或 f |
固定点 |
|
G 或 g |
常规 |
|
N 或 n |
数字 |
|
P 或 p |
百分比 |
|
R 或 r |
往返 |
|
X 或 x |
十六进制 |
可以对许多格式字符串进行修改，以包括用于定义小数点右侧位数的精度说明符。例如，格式设置字符串 D0 将数字格式设置为小数点后面的位数为零。您还可以使用自定义格式字符串，例如 #,###。
下表列出了常见的 .NET Framework 日期格式设置字符串。
| 格式字符串 | 名称 |
|---|---|
|
d |
短日期 |
|
D |
长日期 |
|
t |
短时间 |
|
T |
长时间 |
|
f |
完整日期/时间（短时间） |
|
F |
完整日期/时间（长时间） |
|
g |
常规日期/时间（短时间） |
|
G |
常规日期/时间（长时间） |
|
M 或 m |
月日 |
|
R 或 r |
RFC1123 模式 |
|
Y 或 y |
年月 |
9，交互式报表
- 可以设置参数进行查询，方法是在sql中参数使用@形式，会自动在报表数据中创建参数。
- 参数的值可指定，下拉，多选，若从数据集中取出。
- 数据源除了是sql外，还可以是xml,或webservices
- 可用表达式，加行号，设置单元格颜色、隔行换色
- 选择表头，右键，可做交互式排序
- 在组属性的高级中，可做单层文档，多层文档，父子式层级报表。
- 可设置钻取式报表，点某一项弹出一新的报表。
10，图表、微图形与仪表
- 可做直方图，饼图，3D图
-
图形美化原则：
- 尽量不要让没有提供信息的项目占掉太多空间
- 尽量多用渐变
- 使用CustomerAttributes相关属性
- 微图形：在数据行中显示进度条、迷你图等
- 仪表盘：指针即查值
11，部署
- 在项目中直接部署，或者在报表管理中进行上传
-
在浏览器报表管理中，报表的下拉管理中，可指定如下操作
-
通过报表快照呈现此报表：将数据提前放到reportservertemp数据库中，每次直接从此库中提取
- 如财务数据，可生成快照，并且指定每月生成历史记录，这样在右键报表，查看历史记录的方法可查询不变的数据
12 订阅
- 可通过邮件或共享文件夹方式自动将报表传送到管理者手中
13 权限认证方式：windows,或表单或企业内部自定义。
14，内部系统接入，URL传参方式，可生成html,excel,word,pdf等格式
15，可在webfrom,windowsfrom项目中引入报表进行开发。
BI
SQLServer
BI的核心，其中从下到上包括三个部分，SSIS，SSAS，SSRS
SSIS负责ETL以及整体BI的调度。图形话界面比较直观。
SSAS，分析服务，包括Cube和数据挖掘。它也是跟我们通常所见的表和库相同的另外一种独立的库。
SSRS，报表，包括订阅和发布等功能，最新的版本集成了dundas的一些东西，比之前效果好那么一点。
以上三个模块的开发都是通过visual studio shell。
比较常见的方案：
Windows Server
IIS
SQLServer->SSAS
ETL层自定义框架
前端利用第三方组件自行开发
优点，ETL和UI自己开发，可以解决比较复杂的需求。相对来说对于UI层差别很大，比如据说微软内部很多部门就是自己用Excel去连数据。
缺点，开发维护的成本高。
