SQL SELECT from Multiple Tables

This statement is used to retrieve fields from multiple tables. To do so, we need to use join query to get data from multiple tables.

Let's see the example for the select from multiple tables:

SELECT orders.order_id, suppliers.name 
FROM suppliers
INNER JOIN orders
ON suppliers.supplier_id = orders.supplier_id
ORDER BY order_id;

Let us take three tables, two tables of customers named customer1 and customer2 and the third table is product table.

Customer1 table

Cus_idName1
1Jack
2Jill

Customer2 table

Cus_idName2
1Sandy
2Venus

Product table

P_idCus_idP_name
11Laptop
22Phone
3P1Pen
4P2Notebook

Example syntax to select from multiple tables:

SELECT p. p_id, p.cus_id, p.p_name, c1.name1, c2.name2
FROM product AS p
LEFT JOIN customer1 AS c1
ON p.cus_id=c1.cus_id
LEFT JOIN customer2 AS c2
ON p.cus_id = c2.cus_id

P_idCus_idP_nameP_nameP_name
11LaptopJackNULL
22PhoneJillNULL
3P1PenNULLSandy
4P2NotebookNULLVenus
