内嵌或嵌入SQL和存储过程之对比_MySQL
问：为什么我的内嵌SQL或嵌入SQL 要比我的存储过程运行的快？
答：重编译可能是存储过程运行比较慢的原因。要确认这一点，您需要做一些性能测试，例如：看一下每种类型的查询和调用存储过程的“showplan”情况，并比较查询计划的高速缓存命中率和高速缓存缺失率。您还可以试着在存储过程内部为引用表、视图和过程写出对象拥有者。如下面例子所示：
SELECT * FROM dbo.mytable
这样有助于您重新使用计划并防止高速缓存缺失。

MySQL: String Data Types and CollationsMay 09, 2025 am 12:08 AMThe string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.
MySQL: What length should I use for VARCHARs?May 09, 2025 am 12:06 AMThe best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.
