How do you query all fields of a table in SQL?

To retrieve all fields of a table, you can use the DESCRIBE statement or the SHOW COLUMNS statement in SQL.

Example 1: Use the DESCRIBE statement to retrieve all fields from a table.

DESCRIBE table_name;

Example 2: Use the SHOW COLUMNS statement to retrieve all fields of a table.

SHOW COLUMNS FROM table_name;

Both of these methods can display all the information such as field names, data types, key types, etc. of a specified table. By querying all the fields of a table, one can better understand the structure and design of the table, making it easier for subsequent data operations and analysis.
