    pass_word		VARCHAR(100) NOT NULL,
    create_date	DATETIME DEFAULT CURRENT_TIMESTAMP
);

CREATE TABLE bank_account 
(
	account_id 	INT PRIMARY KEY AUTO_INCREMENT,
    user_id		INT	NOT NULL,
    amount		DECIMAL(22,2) NOT NULL DEFAULT 0,
    create_date	DATETIME DEFAULT CURRENT_TIMESTAMP,
    
    FOREIGN KEY (user_id) REFERENCES registred_user(user_id)
);

CREATE TABLE transactions
(
	transaction_id	INT PRIMARY KEY AUTO_INCREMENT,
    account_id		INT NOT NULL,
    amount		DECIMAL(12,2) NOT NULL,
    t_type		VARCHAR(60) NOT NULL,
	title		VARCHAR(100),
    t_description 	TEXT,
    t_date		DATETIME DEFAULT CURRENT_TIMESTAMP,

	  UPDATE bank_account SET amount = amount + NEW.amount
		WHERE account_id = NEW.account_id;
	END IF;
