Suppose we have two different tables in Database, one having product ID and product name and the other having product ID and price, as shown below,
Table_1
product_id
product_name
1
Car
2
Truck
3
Scooter
4
Bicycle
Table_2
product_id
product_price
1
50000
2
60000
3
5000
4
1000
then to show the product names with their price, we can write an SQL statement (Inner Join) like this,
SELECT a.product_name, b.product_price FROM Table_1 a, Table_2 WHERE a.product_id=b.product_id;
