How do you check the field information of a database table?

You can use the following method to view the field information of a database table:

1. By using SQL queries, you can see the field information of a database table. For example, you can use the following statement to view all the field information of a table:

DESCRIBE table_name;

Or, alternatively

SHOW COLUMNS FROM table_name;

In this case, table_name refers to the name of the table to be queried.

1. Utilize database management tools: Most database management tools (such as MySQL Workbench, Navicat, etc.) provide the functionality to view information about the fields in a database table. These tools allow users to directly see the field names, data types, constraints, and other information about the table.
2. Database metadata is used to store information about the structure of a database system, and you can view the field information of a database table by querying system views or tables. Different database systems have different system views or tables, so you can search for the corresponding metadata information based on the specific database system.

By using the methods above, you can easily view the field information of database tables.
