  最近做到一个项目,涉及到系统的集成。对于SSO单点登陆已经解决,但紧接着一个难点便是两个系统中基础数据的同步。项目情况大致如下:

  系统AB都是采用SQLSERVER 2005 数据库的B/S系统。系统A的数据库中数据未加密,系统B的数据库中数据为加密数据,且因商业合同关系,不能对B数据库进行任何直接操作。系统B提供有相应的webservice,可以用来同步基础数据。

  为了解决这个问题,初步想法是将自动同步交给数据库来完成,小批量的数据修改、添加使用触发器,大量的修改、添加使用中间表和作业调度。

  但这样做的难点就是如果调用webservice。在网上粗略浏览了一下资料,基本上是SQLSERVER调用类库的思路,这个和我之前做的一个数据加密项目类似,唯一不同的是以前的类库中没有webservice。

  既然思路是对的,那么就开始动手。

  1、先是利用VS2005创建了一个类库解决方案

  2、引用要用到的webservice

  3、在类文件中建立UserSynchronization和DepSynchronization类,分别用于同步用户和部门机构。

  为了方便数据库调用,两个类的方法均为static,且每个类只提供一个主调用方法。以DepSynchronization类为例,供数据库调用的方法如下:

  4、编译类库,在release下,生成了四个文件,其中有两个是DLL文件。

  5、数据库中注册类,并映射调用函数。

  在映射函数时出了一个问题,起初我将数据库函数的参数类型设为了varchar,引发了SQL-CLR类型不匹配,原来在C#中的string类型映射过来应该是nvarchar。另外提一下,bool映射到SQLSERVER2005应该是bit。

  6、测试:

  select dbo.SeeyonOperateDepart('Creater','service-admin','19840511suzhou','TEST2014','测试部门');

  系统报错:

  搜索相关资料后发现,编译时生成的另一个DLL文件,***.XmlSerializers.dll,是用来序列化和反序列化webservice引用的,必须注册到SQLSERVER。在可编程性-程序集中右键-新建程序集,将这个类注册。

  7、再次测试OK

MySQL: String Data Types and CollationsMySQL: String Data Types and CollationsMay 09, 2025 am 12:08 AM

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
