## Creating database
|
||||
|
||||
```sql
|
||||
CREATE DATABASE Database_A3;
|
||||
USE Database_A3;
|
||||
|
||||
```
|
||||
|
||||
## Creating tables and specify primary keys:
|
||||
|
||||
```sql
|
||||
CREATE TABLE Account(acc_no INT, branch_name VARCHAR(50), balance INT, PRIMARY KEY (acc_no));
|
||||
CREATE TABLE Branch(branch_name VARCHAR(50), branch_city VARCHAR(50), assets INT, PRIMARY KEY (branch_name));
|
||||
CREATE TABLE Customer (cust_name VARCHAR(50), cust_street VARCHAR(50), cust_city VARCHAR(50), PRIMARY KEY (cust_name));
|
||||
CREATE TABLE Depositor (cust_name VARCHAR(50), acc_no INT);
|
||||
CREATE TABLE Loan (loan_no INT, branch_name VARCHAR(50), amount INT, PRIMARY KEY (loan_no));
|
||||
CREATE TABLE Borrower (cust_name VARCHAR(50), loan_no INT);
|
||||
|
||||
```
|
||||
|
||||
## Altering tables to specify foreign keys
|
||||
|
||||
```sql
|
||||
ALTER TABLE Account ADD FOREIGN KEY (branch_name) REFERENCES Branch(branch_name);
|
||||
ALTER TABLE Depositor ADD FOREIGN KEY (cust_name) REFERENCES Customer (cust_name);
|
||||
ALTER TABLE Depositor ADD FOREIGN KEY (acc_no) REFERENCES Account (acc_no);
|
||||
ALTER TABLE Loan ADD FOREIGN KEY (branch_name) REFERENCES Branch (branch_name);
|
||||
ALTER TABLE Borrower ADD FOREIGN KEY (cust_name) REFERENCES Customer (cust_name);
|
||||
ALTER TABLE Borrower ADD FOREIGN KEY (loan_no) REFERENCES Loan (loan_no);
|
||||
|
||||
```
|
||||
|
||||
