最近在用mysqldump备份时,想要把数据表和数据分开备份,因此做了2次备份。 执行备份数据库表结构时,指定了 --skip-opt 选项,相当于禁用下面几个参数: --add-drop-table, --add-locks,--create-options, --quick, --extended-insert,--lock-tables, --set
最近在用mysqldump备份时,想要把数据表和数据分开备份,因此做了2次备份。
执行备份数据库表结构时,指定了 --skip-opt 选项,相当于禁用下面几个参数:
--add-drop-table, --add-locks, --create-options, --quick, --extended-insert, --lock-tables, --set-charset, and --disable-keys
选项 --create-option 看起来比较不起眼:
-a, --create-options Include all MySQL specific create options.
事实上,如果把它disable的话,备份出来的表结构,会少了:
AUTO_INCREMENT --PK字段的AUTO_INCREMENT属性以及数据表的AUTO_INCREMENT属性都会丢掉 ENGINE=InnoDB DEFAULT CHARSET=utf8 --数据表的引擎、字符集属性
等MySQL特有的数据表属性,需要注意下,版本信息见下:
Server version: 5.5.19-55-log Percona Server (GPL), Release rel24.0, Revision 204 mysqldump --version mysqldump Ver 10.13 Distrib 5.5.19, for Linux (x86_64)

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.

Mastering the method of adding MySQL users is crucial for database administrators and developers because it ensures the security and access control of the database. 1) Create a new user using the CREATEUSER command, 2) Assign permissions through the GRANT command, 3) Use FLUSHPRIVILEGES to ensure permissions take effect, 4) Regularly audit and clean user accounts to maintain performance and security.

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.
