修改MySQL的数据库引擎为INNODB的方法_MySQL
对于MySQL数据库,如果你要使用事务以及行级锁就必须使用INNODB引擎。如果你要使用全文索引,那必须使用myisam。 INNODB的实用性,安全性,稳定性更高但是效率比MYISAM稍差,但是有的功能是MYISAM没有的。修改MySQL的引擎为INNODB,可以使用外键,事务等功能,性能高。本文主要介绍如何修改MySQL数据库引擎为INNODB,接下来我们开始介绍。
首先修改my.ini,在[mysqld]下加上:
default-storage-engine=INNODB
其中的蓝色字体是要指定的数据库引擎名称。
用sql语句修改已经建成表的引擎:
alter table tableName type=InnoDB
下面贴出我的my.ini文件供参考:
[mysqld] basedir=C:\Program Files\VertrigoServ\Mysql\ datadir=C:\Program Files\VertrigoServ\Mysql\data\ port =3306 key_buffer =64M max_allowed_packet =1M table_cache =128 sort_buffer_size =512K net_buffer_length =8K read_buffer_size =256K read_rnd_buffer_size =512K myisam_sort_buffer_size =68M default-storage-engine=INNODB [mysqldump] quick max_allowed_packet =116M [mysql] no-auto-rehash # Remove the next comment character if you are not familiar with SQL #safe-updates [isamchk] key_buffer =20M sort_buffer_size =20M read_buffer =62M write_buffer =62M [myisamchk] key_buffer =20M sort_buffer_size =20M read_buffer =62M write_buffer =62M [mysqlhotcopy] interactive-timeout
按照以上的代码提示操作,我们就能够成功地修改MySQL数据库引擎为INNODB了。本文就介绍到这里,相信一定会带给您收获的!

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.

InnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

MySQL is suitable for small and large enterprises. 1) Small businesses can use MySQL for basic data management, such as storing customer information. 2) Large enterprises can use MySQL to process massive data and complex business logic to optimize query performance and transaction processing.

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.
