查看mysql表结构信息
一、简单描述表结构,字段类型 desc tabl_name; 或 describe columns ; 显示表结构,字段类型,主键,是否为空等属性,但不显示外键和字段的注释。 二, 查看表生成的 DDL show create table 表名 ; 这个命令虽然显示起来不是太容易看, 这个不是问题可以用
一、简单描述表结构,字段类型
desc tabl_name; 或describe columns;
显示表结构,字段类型,主键,是否为空等属性,但不显示外键和字段的注释。
二,查看表生成的DDL
show create table 表名;
这个命令虽然显示起来不是太容易看, 这个不是问题可以用\G来结尾,使得结果容易阅读;该命令把创建表的DDL显示出来,于是表结构、类型,外键,备注全部显示出来了。我比较喜欢这个命令:输入简单,显示结果全面。
三,查询表中列的注释信息
use information_schema
select * from columns where table_name = '表名' ;
四、查看表的注释
select table_name,table_comment frominformation_schema.tables where table_schema = 'db' and table_name='表名'
五,只查询列名和注释
select column_name, column_comment from information_schema.columnswhere table_schema ='db' and table_name = '表名' ;

Big data structure processing skills: Chunking: Break down the data set and process it in chunks to reduce memory consumption. Generator: Generate data items one by one without loading the entire data set, suitable for unlimited data sets. Streaming: Read files or query results line by line, suitable for large files or remote data. External storage: For very large data sets, store the data in a database or NoSQL.

MySQL query performance can be optimized by building indexes that reduce lookup time from linear complexity to logarithmic complexity. Use PreparedStatements to prevent SQL injection and improve query performance. Limit query results and reduce the amount of data processed by the server. Optimize join queries, including using appropriate join types, creating indexes, and considering using subqueries. Analyze queries to identify bottlenecks; use caching to reduce database load; optimize PHP code to minimize overhead.

Oracle database and MySQL are both databases based on the relational model, but Oracle is superior in terms of compatibility, scalability, data types and security; while MySQL focuses on speed and flexibility and is more suitable for small to medium-sized data sets. . ① Oracle provides a wide range of data types, ② provides advanced security features, ③ is suitable for enterprise-level applications; ① MySQL supports NoSQL data types, ② has fewer security measures, and ③ is suitable for small to medium-sized applications.
