In this article, we would like to show you how to find rows with NULL value in one of theĀ columns in MS SQL Server.

Quick solution:

SELECT *
FROM [table_name] 
WHERE [column_name] IS NULL;

Sometimes your data can be an empty string. You can select such rows with the below query:

SELECT FROM [table_name] WHERE [column_name] = '';

Practical example

To show how to find rows with NULL value in one of theĀ columns, we will use the following table:

MS SQL Server - select rows with NULL values - example data
MS SQL Server - select rows with NULL values - example data

Note:

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

Example

In this example, we will select rows fromĀ usersĀ table with NULL value inĀ emailĀ column.

Query:

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

Result:

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

Database preparation

create_tables.sqlĀ file:

CREATE TABLE [users] (
	[id] INT IDENTITY(1,1),
	[name] VARCHAR(50) NOT NULL,
	[surname] VARCHAR(50) NOT NULL,
	[email] VARCHAR(50),
	PRIMARY KEY ([id])
);

insert_data.sqlĀ file:

INSERT INTO [users]
	( [name], [surname], [email])
VALUES
	('John', 'Stewart', 'john@email.com'),
	('Chris', 'Brown', NULL),
	('Kate', 'Lewis', NULL),
	('Ailisa', 'Gomez', 'ailisa@email.com'),
	('Gwendolyn', 'James', NULL),
	('Simon', 'Collins', NULL),
	('Taylor', 'Martin', NULL),
	('Andrew', 'Thompson', 'andrew@email.com');
