十三、mysql 分区之 RANGE && LIST_MySQL
1.RANGE 分区 创建实例: CREATE TABLE EMP ( id int not null primary key auto_increment, name char(25) not null default '' ) PARTITION BY RANGE (id) ( 将字段id定义为分区的字段 PARTITION P0 VALUES LESS THAN (100), 99以下的id都归到p0分区 PARTITION P1 VALUES LESS THAN (200), 100-199 PARTITION P2 VALUES LESS THAN (300) 200-299 ); PS::因为默认会将0也算进去,所以P0实际可以存储0-99或-数 PS::要么不包含主键,如果要包含主键,那么分区字段也必须是主键 PS::mysql5.5以上支持日期进行分区,有什么作用,^_^,你可以想到的 2.List分区 创建实例: CREATE TABLE LIST_EMP ( tid int not null PRIMARY key auto_increment, tname char(20) ) PARTITION BY LIST (tid) ( PARTITION P0 VALUES IN (1,3,5,7,9), PARTITION P1 VALUES IN (2,4,6,8,10) ); PS::通过上面的2种分区不难看出,RANGE分区是指定一个范围,而List分区是指定一个列表,在list中,只有指定的值才能存进去! PS::个人觉得List分区更多可以用在分类上面 测试: insert into list_emp values (null,'Php'); insert into list_emp values (null,'Php'); insert into list_emp values (null,'Php'); insert into list_emp values (null,'Php'); insert into list_emp values (null,'Php'); insert into list_emp values (null,'Php'); insert into list_emp values (null,'Php'); insert into list_emp values (null,'Php'); insert into list_emp values (null,'Php'); insert into list_emp values (null,'Php'); insert into list_emp values (null,'Php');ERROR 1526 (HY000): Table has no partition for value 11 PS::第11条数据的时候报错,因为没有任何分区表包含了它

Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

Yes, MySQL can be installed on Windows 7, and although Microsoft has stopped supporting Windows 7, MySQL is still compatible with it. However, the following points should be noted during the installation process: Download the MySQL installer for Windows. Select the appropriate version of MySQL (community or enterprise). Select the appropriate installation directory and character set during the installation process. Set the root user password and keep it properly. Connect to the database for testing. Note the compatibility and security issues on Windows 7, and it is recommended to upgrade to a supported operating system.

InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.

The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values and pointers to data rows, and is suitable for non-primary key column queries.

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

In MySQL database, the relationship between the user and the database is defined by permissions and tables. The user has a username and password to access the database. Permissions are granted through the GRANT command, while the table is created by the CREATE TABLE command. To establish a relationship between a user and a database, you need to create a database, create a user, and then grant permissions.

MySQL supports four index types: B-Tree, Hash, Full-text, and Spatial. 1.B-Tree index is suitable for equal value search, range query and sorting. 2. Hash index is suitable for equal value searches, but does not support range query and sorting. 3. Full-text index is used for full-text search and is suitable for processing large amounts of text data. 4. Spatial index is used for geospatial data query and is suitable for GIS applications.

MySQL and MariaDB can coexist, but need to be configured with caution. The key is to allocate different port numbers and data directories to each database, and adjust parameters such as memory allocation and cache size. Connection pooling, application configuration, and version differences also need to be considered and need to be carefully tested and planned to avoid pitfalls. Running two databases simultaneously can cause performance problems in situations where resources are limited.
