SQL Tutorial
What is SQL SQL SELECT SQL SELECT DISTINCT SQL WHERE SQL INSERT SQL UPDATE SQL DELETE SQL AND, OR & NOT Clause SQL ORDER BY SQL LIKE Clause SQL IN Operator SQL BETWEEN Operator SQL MAX() and MIN() SQL COUNTSQL JOIN
SQL JOIN SQL INNER JOIN SQL LEFT JOIN SQL RIGHT JOIN SQL FULL OUTER JOINSQL RIGHT JOIN
The RIGHT JOIN keyword returns all records from the right table (table2), and the matching records from the left table (table1). The result is 0 records from the left side, if there is no match.
Syntax:
SELECT column_name(s)
FROM table1
RIGHT JOIN table2
ON table1.column_name = table2.column_name;
Customers table:
customer_id | fullname |
---|---|
1 | Kailash |
2 | Amit |
3 | Siddarth |
4 | Vikas |
Orders table:
order_id | amount | customer |
---|---|---|
1 | 2000 | 2 |
2 | 3000 | 4 |
3 | 3500 | 5 |
4 | 2500 | 7 |
Here, the SQL command selects customer_id and fullname columns (from the Customers table) and the amount column (from the Orders table).
QUERY:
SELECT Customers.customer_id, Customers.fullname, Orders.amount
FROM Customers
RIGHT JOIN Orders
ON Customers.customer_id = Orders.customer;
And, the result set will contain those rows where there is a match between customer_id (of the Customers table) and customer (of the Orders table) along with all the remaining rows from the Orders table.
Result:
customer_id | fullname | amount |
---|---|---|
