需要解决的问题有两个，一个是MFC本身，即所用动态连接库文件另一个就是数据库引擎动态连接库，通过在项目属性中设置在静态类库中使用MFC，在生成时，VS会将所用的DLL打包到可执行文件中。另外数据库的连接使用了ADO，在生成时配置为Release，

需要解决的问题有两个，一个是MFC本身，即所用动态连接库文件

另一个就是数据库引擎

动态连接库，通过在项目属性中设置在静态类库中使用MFC，在生成时，VS会将所用的DLL打包到可执行文件中。

另外数据库的连接使用了ADO，在生成时配置为Release，在可执行文件所在目录下会生成两个文件msado15.tlh和msado15.tli，提供ADO连接数据库所用的连接库。

这次写的小程序为了方便移植使用了Access数据库，数据库文件.mdb可以和可执行文件一起打包，但发现换了机器之后程序就打不开了，提示错误为“未找到提供程序，应用程序未能正确安装”。

这里指的提供程序就是在连接字符串中Provider字段指示的值。

这个程序的连接字符串是“Provider=Microsoft.ACE.OLEDB.12.0;Data Source=.\\Data\\RIB.mdb;Mode=ReadWrite|Share Deny None;Persist Security Info=False”

提供程序就是微软的Access数据库引擎，可以在这里下载到：AccessEngine。安装完成后程序就可以运行了。因为DataSource字段指定相对路径，所以数据库文件会被放置在./Data/目录下。

MySQL's Role: Databases in Web ApplicationsApr 17, 2025 am 12:23 AM

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

MySQL: Building Your First DatabaseApr 17, 2025 am 12:22 AM

The steps to build a MySQL database include: 1. Create a database and table, 2. Insert data, and 3. Conduct queries. First, use the CREATEDATABASE and CREATETABLE statements to create the database and table, then use the INSERTINTO statement to insert the data, and finally use the SELECT statement to query the data.

MySQL: A Beginner-Friendly Approach to Data StorageApr 17, 2025 am 12:21 AM

MySQL is suitable for beginners because it is easy to use and powerful. 1.MySQL is a relational database, and uses SQL for CRUD operations. 2. It is simple to install and requires the root user password to be configured. 3. Use INSERT, UPDATE, DELETE, and SELECT to perform data operations. 4. ORDERBY, WHERE and JOIN can be used for complex queries. 5. Debugging requires checking the syntax and use EXPLAIN to analyze the query. 6. Optimization suggestions include using indexes, choosing the right data type and good programming habits.

Is MySQL Beginner-Friendly? Assessing the Learning CurveApr 17, 2025 am 12:19 AM

MySQL is suitable for beginners because: 1) easy to install and configure, 2) rich learning resources, 3) intuitive SQL syntax, 4) powerful tool support. Nevertheless, beginners need to overcome challenges such as database design, query optimization, security management, and data backup.

Explain the ACID properties (Atomicity, Consistency, Isolation, Durability).Apr 16, 2025 am 12:20 AM

ACID attributes include atomicity, consistency, isolation and durability, and are the cornerstone of database design. 1. Atomicity ensures that the transaction is either completely successful or completely failed. 2. Consistency ensures that the database remains consistent before and after a transaction. 3. Isolation ensures that transactions do not interfere with each other. 4. Persistence ensures that data is permanently saved after transaction submission.

MySQL: Database Management System vs. Programming LanguageApr 16, 2025 am 12:19 AM

MySQL is not only a database management system (DBMS) but also closely related to programming languages. 1) As a DBMS, MySQL is used to store, organize and retrieve data, and optimizing indexes can improve query performance. 2) Combining SQL with programming languages, embedded in Python, using ORM tools such as SQLAlchemy can simplify operations. 3) Performance optimization includes indexing, querying, caching, library and table division and transaction management.

MySQL: Managing Data with SQL CommandsApr 16, 2025 am 12:19 AM

MySQL uses SQL commands to manage data. 1. Basic commands include SELECT, INSERT, UPDATE and DELETE. 2. Advanced usage involves JOIN, subquery and aggregate functions. 3. Common errors include syntax, logic and performance issues. 4. Optimization tips include using indexes, avoiding SELECT* and using LIMIT.
