1 查看系统支持的存储引擎

show engines;

2 查看表使用的存储引擎

两种方法:

a、show table status from db_name where;

b、show create table table_name;

如果显示的格式不好看,可以用\g代替行尾分号

有人说用第二种方法不准确,我试了下,关闭掉原先默认的Innodb引擎后根本无法执行show create table table_name指令,因为之前建的是Innodb表,,关掉后默认用MyISAM引擎,导致Innodb表数据无法被正确读取。

3 修改表引擎方法

alter table table_name engine=innodb;

4 关闭Innodb引擎方法

关闭mysql服务: net stop mysql

找到mysql安装目录下的my.ini文件:

找到default-storage-engine=INNODB 改为default-storage-engine=MYISAM

找到#skip-innodb 改为skip-innodb

启动mysql服务:net start mysql

linux

MySQL BLOB: how to optimize BLOBs requestsMySQL BLOB: how to optimize BLOBs requestsMay 13, 2025 am 12:03 AM

Optimizing MySQLBLOB requests can be done through the following strategies: 1. Reduce the frequency of BLOB query, use independent requests or delay loading; 2. Select the appropriate BLOB type (such as TINYBLOB); 3. Separate the BLOB data into separate tables; 4. Compress the BLOB data at the application layer; 5. Index the BLOB metadata. These methods can effectively improve performance by combining monitoring, caching and data sharding in actual applications.

MySQL: String Data Types and Indexing: Best PracticesMySQL: String Data Types and Indexing: Best PracticesMay 12, 2025 am 12:11 AM

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.

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),
