MS SQL Server - search for NULL values in multiple columns

In this article, we would like to show you how to find rows with NULL values in many columns in MS SQL Server.

Quick solution:

SELECT *
FROM [table_name] 
WHERE [column1] IS NULL AND [column2] IS NULL AND [columnN] IS NULL;

Practical example

To show how to find rows with NULL values in many columns, we will use the following table:

MS SQL Server - select rows with NULL values in multiple columns - example data
MS SQL Server - select rows with NULL values in multiple columns - example data

Note:

At the end of this article you can find database preparation SQL queries.

Example 1

In this example, we will select all rows with NULL value both in email and department_id column using IS NULL and AND keywords.

Query:

SELECT *
FROM [users]
WHERE [email] IS NULL AND [department_id] IS NULL;

Result:

MS SQL Server - select rows with multiple NULL column values - result
MS SQL Server - select rows with multiple NULL column values - results

Database preparation

create_tables.sql file:

CREATE TABLE [users] (
	[id] INT IDENTITY(1,1),
	[name] VARCHAR(50) NOT NULL,
	[surname] VARCHAR(50) NOT NULL,
	[email] VARCHAR(100),
	[department_id] INT,
    [salary] DECIMAL(15,2) NOT NULL,
	PRIMARY KEY ([id])
);

insert_data.sql file:

INSERT INTO [users]
	( [name], [surname], [email], [department_id], [salary])
VALUES
	('John', 'Stewart', 'john@email.com', 1, '3512.00'),
	('Chris', 'Brown', 'chris@email.com', 2, '1344.00'),
	('Kate', 'Lewis', NULL, 3, '6574.00'),
	('Ailisa', 'Gomez', 'ailisa@email.com', 2, '6500.00'),
	('Gwendolyn', 'James', NULL, NULL, '4200.00'),
	('Simon', 'Collins', NULL, 4, '3320.00'),
	('Taylor', 'Martin', NULL, NULL, '1500.00'),
	('Andrew', 'Thompson', 'andrew@email.com', NULL, '2100.00');
