mysql自带的command line client中创建表的时候，遇到int+数字的
下面是我遇到的问题，截图如下，最后的解决办法如下：在int数字的字段上加上一个“像单引号的东西”， 注意，并不是单引号，单引号仍然会报错。 另外，float类型的字段也会有这样的，float数字的字段也要加上这种像单引号的东西。 特别是float这个字段，我总
下面是我遇到的问题，截图如下，最后的解决办法如下：在int+数字的字段上加上一个“像单引号的东西”，
注意，并不是单引号，单引号仍然会报错。
另外，float类型的字段也会有这样的，float+数字的字段也要加上这种像单引号的东西。
特别是float这个字段，我总感觉是mysql的bug,只有float4的时候是不可以
当然今天在命令行中创建表的时候，还发现，Varchar类型的字段必须指定字符串的长度：如下图

How to use single threaded redis
Apr 10, 2025 pm 07:12 PM
Redis uses a single threaded architecture to provide high performance, simplicity, and consistency. It utilizes I/O multiplexing, event loops, non-blocking I/O, and shared memory to improve concurrency, but with limitations of concurrency limitations, single point of failure, and unsuitable for write-intensive workloads.
MySQL and SQL: Essential Skills for Developers
Apr 10, 2025 am 09:30 AM
MySQL and SQL are essential skills for developers. 1.MySQL is an open source relational database management system, and SQL is the standard language used to manage and operate databases. 2.MySQL supports multiple storage engines through efficient data storage and retrieval functions, and SQL completes complex data operations through simple statements. 3. Examples of usage include basic queries and advanced queries, such as filtering and sorting by condition. 4. Common errors include syntax errors and performance issues, which can be optimized by checking SQL statements and using EXPLAIN commands. 5. Performance optimization techniques include using indexes, avoiding full table scanning, optimizing JOIN operations and improving code readability.
