✅ SQL Representation for Storing Thailand’s Provinces

Here is the SQL table schema and INSERT statements for the 77 provinces of Thailand:

sql

-- Table for Thailand provinces
CREATE TABLE thailand_provinces (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(100) NOT NULL,
    code VARCHAR(5) NOT NULL
);

-- Sample insert statements (only first few shown for brevity)
INSERT INTO thailand_provinces (name, code) VALUES
('Amnat Charoen', 'AC'),
('Ang Thong', 'AT'),
('Bangkok', 'BK'),
('Bueng Kan', 'BN'),
('Buri Ram', 'BR'),
('Chachoengsao', 'CC'),
('Chai Nat', 'CN'),
('Chaiyaphum', 'CP'),
('Chanthaburi', 'CT'),
('Chiang Mai', 'CM'),
('Chiang Rai', 'CR'),
('Chonburi', 'CB'),
('Chumphon', 'CPN'),
('Kalasin', 'KS'),
('Kamphaeng Phet', 'KP'),
-- (Continue for all 77 provinces) ...
('Yala', 'YL'),
('Yasothon', 'YS');

This setup supports regional functionality in Thai government systems, logistics, travel apps, and administrative software.
