To query the field information of a table in a MySQL database, you can use the following methods:

  1. Use the DESCRIBE statement:
DESCRIBE table_name;
  1. Use the SHOW COLUMNS statement:
SHOW COLUMNS FROM table_name;
  1. Retrieve the COLUMNS table in the information_schema database.
SELECT column_name, data_type, column_type, is_nullable
FROM information_schema.columns
WHERE table_schema = 'your_database_name' AND table_name = 'your_table_name';

Replace “your_database_name” with the name of your database, and “your_table_name” with the table you want to query.

All three methods can be used to query the specified table for information on field names, data types, column types, and whether they can be nullable.
