0 points
In this article, we would like to show you how to use RIGHT JOIN in MS SQL Server.
Quick solution:
xxxxxxxxxx1
SELECT [column1], [column2], [columnN]2

RIGHT JOIN [table2]4
ON [table1].[column_name] = [table2].[column_name];To show how the RIGHT JOIN works, we will use the following tables:
Note:
At the end of this article you can find databases preparation SQL queries.
In this example, we will select all information about users and departments, even when there are no users assigned to a department.
Query:
xxxxxxxxxx1
SELECT * FROM [users]2
RIGHT JOIN [departments] 3
ON [departments].[id] = [users].[department_id];Output:
create_tables.sql file:
xxxxxxxxxx1
CREATE TABLE [departments] (2
[id] INT NOT NULL,3
[department_name] VARCHAR(50) NOT NULL,4
[location] VARCHAR(50) NULL,5
PRIMARY KEY ([id])6
);7
