编写 SQL 语句一直都是比较纳闷的事，编写时没有一个良好的检错机制，只能运行时才能发现错误，特别是关联的表一多起来，思绪不免会被搞得晕头转向最后不知迷失在什么地方了。近日偶然发现并不是 M$ 没有提供一个良好的傻瓜化界面给我们这帮懒兄懒弟们使用，而是我们自己视而不见，那就是 SQL Server 中的视图管理器，它不仅可以让我们方便地在多个表中进行查询而不去理会他们之间的关系（当然多个表之间必须存在必要的关系），还可以用它进行别名、排序、条件等的设置，然后自动产生出良好风格的 SQL SELECT语句，而且还可以测试运行结果。废话就说到这了，看看下面这张图片再自己亲自体验一下吧 :-)

MySQL: String Data Types and CollationsMay 09, 2025 am 12:08 AM

The 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 AM

The 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.
