What is the usage of the MySQL describe command?

DESCRIBE 命令用于显示指定表的结构，包括每个字段的名称、类型、Null 属性、键等信息。其用法如下：

DESCRIBE table_name;

Alternatively

DESC table_name;

Both of these commands can be used to view the structure information of a specified table. When executed, a table will be returned containing information for each field of the table.
