How can I query all columns in a table in MySQL?

To retrieve all columns in a MySQL table, you can use the following SQL query statement:

SHOW COLUMNS FROM your_table_name;

Please replace your_table_name with the actual name of the table you want to query. This SQL query will return information about all columns in the specified table, including column names, data types, key information, default values, extra properties, etc. This allows you to quickly view the table structure and information about all columns.
