数据库（银行数据库表构建）

题目： 通过所提供的E-R图和数据库模型图完成库表的创建，并插入适量的数据.要求必须使用SQL命令进行构建。

表1 UserInfo

**建表**
CREATE TABLE USERINFO (
	customerID INT AUTO_INCREMENT COMMENT '客户编号',
	customerName CHAR(50) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NOT NULL COMMENT '开户名',
	PID CHAR(18) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NOT NULL COMMENT '身份证号',
	telephone CHAR(11) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NOT NULL COMMENT '联系电话',
	address VARCHAR(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NULL DEFAULT NULL COMMENT '居住地址',
	PRIMARY KEY (customerID) USING BTREE,
	UNIQUE INDEX PID(PID) USING BTREE
)ENGINE = InnoDB AUTO_INCREMENT = 1 CHARACTER SET = utf8mb4 COLLATE = utf8mb4_general_ci;

表2 CardInfo

**设置外键**
ALTER TABLE CARDINFO ADD CONSTRAINT s_id FOREIGN KEY (customerID) REFERENCES USERINFO (customerID); 
ALTER TABLE CARDINFO ADD CONSTRAINT saving_id FOREIGN KEY (savingID) REFERENCES DEPOSIT (savingID);  //需建立DEPOSIT表后输入

**建表**
CREATE TABLE CARDINFO (
	cardID CHAR(20) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NOT NULL COMMENT '卡号',
	savingID VARCHAR(50) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NOT NULL COMMENT '存款类型',
	openDate TIMESTAMP NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE
CURRENT_TIMESTAMP COMMENT '开户日期',
	openMoney 	DECIMAL(18,2) NOT NULL COMMENT '开户金额',
	balance DECIMAL(18,2) NOT NULL COMMENT '余额',
	password VARCHAR(6) NOT NULL DEFAULT('888888') COMMENT '密码',
	isReportLoss BIT NOT NULL DEFAULT(1) COMMENT '是否挂失，是 0 否 1',
	customerID INT NOT NULL COMMENT '客户编号',
	PRIMARY KEY (cardID)
)ENGINE = InnoDB AUTO_INCREMENT = 1 CHARACTER SET = utf8mb4 COLLATE = utf8mb4_general_ci;

测试：

表3 TradeInfo

**外键**
ALTER TABLE TRADEINFO ADD CONSTRAINT card_id FOREIGN KEY (cardID) REFERENCES CARDINFO (cardID);

**建表**
CREATE TABLE TRADEINFO (
	transDate TIMESTAMP NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE
CURRENT_TIMESTAMP COMMENT '交易日期',
	cardID CHAR(20) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NOT NULL COMMENT '卡号',
	transType CHAR(50) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NOT NULL COMMENT '交易类型',
	transMoney DECIMAL(18,2) NOT NULL COMMENT '交易金额',
	remark TEXT CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NULL DEFAULT NULL COMMENT '居住地址'
)ENGINE = InnoDB AUTO_INCREMENT = 1 CHARACTER SET = utf8mb4 COLLATE = utf8mb4_general_ci;

测试：

表4 Deposit

**建表**
CREATE TABLE DEPOSIT (
	savingID VARCHAR(50) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci  COMMENT '存款类型',
	savingName VARCHAR(50) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NOT NULL COMMENT '存款类型名称',
	descrip VARCHAR(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NULL DEFAULT NULL COMMENT '描述',
	PRIMARY KEY (savingID)
)ENGINE = InnoDB AUTO_INCREMENT = 1 CHARACTER SET = utf8mb4 COLLATE = utf8mb4_general_ci;
