在MySQL中，可以通過以下步驟來使用contract：
CREATE TABLE contract ( id INT PRIMARY KEY, name VARCHAR(50), start_date DATE, end_date DATE, amount DECIMAL(10, 2) );
INSERT INTO contract (id, name, start_date, end_date, amount) VALUES (1, ‘Contract A’, ‘2022-01-01’, ‘2022-12-31’, 10000.00);
SELECT * FROM contract;
UPDATE contract SET amount = 12000.00 WHERE id = 1;
DELETE FROM contract WHERE id = 1;
通過以上步驟，可以使用contract表格來管理合同相關的數據。
