Example - INNER JOINS
(a) CUSTOMERS table is as follows:
| ID | NAME |
+----+----------+
| 1 | Ramesh |
| 2 | Khilan |
| 3 | kaushik |
| 4 | Chaitali |
| 5 | Hardik |
| 6 | Komal |
(b) Another table is ORDERS as follows:
| OID | ID | AMOUNT |
+-----+-----+--------+
| 102 | 3 | 3000 |
| 100 | 3 | 1500 |
| 101 | 2 | 1560 |
| 103 | 4 | 2060 |
Now, let us join these two tables using INNER JOIN as follows:
SQL> SELECT ID, NAME, AMOUNT
FROM CUSTOMERS
INNER JOIN ORDERS
ON CUSTOMERS.ID = ORDERS.CUSTOMER_ID;
This would produce the following result:
| ID | NAME | AMOUNT |
+----+----------+--------+
| 3 | kaushik | 3000 |
| 3 | kaushik | 1500 |
| 2 | Khilan | 1560 |
| 4 | Chaitali | 2060 |
