Markdown 支持两种形式的链接语法: 行内式 和 参考式。不管是哪一种,链接文字都是用 [方括号] 来标记. 例如,如果要链接显示为 “Code”, 就直接写 [Code]
.
要建立一个行内式的链接,只要在方块括号后面紧接着圆括号并插入网址链接即可 (例如: [Code](http://code.csdn.net/)
)。 如果你是要链接到同样主机的资源,你可以使用相对路径。
参考式链接需要用两个方括号来标示[my internal link][Code]
将会链接到一个参考链接 Code
。
参考式连接的声明方式为中括号后跟冒号,例如[Code]: http://code.csdn.net

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.
