SQL Right JOIN

The RIGHT JOIN keyword returns you  all rows from the right table (table_name1), incase if there are no matches in the left table (table_name2). .The RIGHT  JOIN  is also called RIGHT OUTER JOIN.

Understand with Example

The Tutorial illustrate an example from RIGHT OUTER JOIN. In this example, The table Stu_Table and Lib_Table is created using create statement. The insert into statement adds the records or rows to the tables respectively. Finally  the select statement returns you the records set from respective tables.

Create Table Stu_Table

create table Stu_Table(Stu_Id integer(2), Stu_Name varchar(15), Stu_Class  varchar(10));

Create Table Lib_Table

create table Lib_Table(Stu_Id integer(2), Lib_no integer(5));

Insert data into Stu_Table

insert into Stu_Table values(1,'Komal',10);
insert into Stu_Table values(2,'Ajay',10);
insert into Stu_Table values(3,'Rakesh',10);
insert into Stu_Table values(4,'Bhanu',10);
insert into Stu_Table values(5,'Santosh',10);
insert into Stu_Table values(8,'Tanuj',10);

 Insert data into Lib_Table

insert into Lib_Table values(1,101);
insert into Lib_Table values(2,102);
insert into Lib_Table values(3,103);
insert into Lib_Table values(4,104);
insert into Lib_Table values(5,105);
insert into Lib_Table values(6,106);
insert into Lib_Table values(7,107);

Stu_Table

Lib_Table

SQL RIGHT JOIN Syntax

The SQL RIGHT JOIN Syntax display you all the records from the right table, even there are no matches with the left table. The Syntax used for SQL RIGHT OUTER JOIN is given below:

SELECT column_name(s)
FROM table_name1
right JOIN table_name2 
ON table_name1.column_name=table_name2.column_name

Use Right JOIN in SQL Query

The Example shows you the RIGHT JOIN in SQL Query. In this  Example, we use RIGHT OUTER JOIN, which displays the records from two tables. The table contain return all record from table1,even there are no matches with the table 2.

select s.stu_id, s.stu_name, s.stu_class, l.lib_no 
from stu_table as s Right JOIN lib_table as l
on l.stu_id = s.stu_id
