使用SQL数据定义语言可以创建以下银行-客户数据库。您应该使用其他8个不同类型的唯一完整性约束来正确地定义主键和外键(检查可以多次使用)。提交适当的包含所有完整性约束的DDL和DML语句。在插入数据后,您需要将三个表的屏幕截图放到文档中。

SQL语言,对你操作数据库有很大的帮助,里面有一些基础的知识
我可以回答这个问题。以下是DDL和DML语句:
DDL语句:
CREATE TABLE Bank (
BankID INT PRIMARY KEY,
BankName VARCHAR(50) NOT NULL,
BankAddress VARCHAR(100) NOT NULL
);
CREATE TABLE Customer (
CustomerID INT PRIMARY KEY,
CustomerName VARCHAR(50) NOT NULL,
CustomerAddress VARCHAR(100) NOT NULL,
CustomerPhone VARCHAR(20) NOT NULL
);
CREATE TABLE Account (
AccountNumber INT PRIMARY KEY,
AccountType VARCHAR(20) NOT NULL,
Balance DECIMAL(10,2) NOT NULL,
CustomerID INT NOT NULL,
BankID INT NOT NULL,
CONSTRAINT FK_Customer FOREIGN KEY (CustomerID) REFERENCES Customer(CustomerID),
CONSTRAINT FK_Bank FOREIGN KEY (BankID) REFERENCES Bank(BankID)
);
DML语句:
INSERT INTO Bank (BankID, BankName, BankAddress) VALUES (1, 'ABC Bank', '123 Main St.');
INSERT INTO Bank (BankID, BankName, BankAddress) VALUES (2, 'XYZ Bank', '456 Oak St.');
INSERT INTO Customer (CustomerID, CustomerName, CustomerAddress, CustomerPhone) VALUES (1, 'John Smith', '789 Elm St.', '555-1234');
INSERT INTO Customer (CustomerID, CustomerName, CustomerAddress, CustomerPhone) VALUES (2, 'Jane Doe', '321 Maple Ave.', '555-5678');
INSERT INTO Account (AccountNumber, AccountType, Balance, CustomerID, BankID) VALUES (1001, 'Checking', 500.00, 1, 1);
INSERT INTO Account (AccountNumber, AccountType, Balance, CustomerID, BankID) VALUES (1002, 'Savings', 10000.00, 1, 2);
INSERT INTO Account (AccountNumber, AccountType, Balance, CustomerID, BankID) VALUES (1003, 'Checking', 750.00, 2, 1);
请注意,我是一个AI语言模型,不是真正的数据库管理员,因此这些语句可能不是完美的。请在实际使用之前进行测试和修改。
