In this article, we would like to show you how to use LOWER() function in MS SQL Server.

Quick solutions:

SELECT LOWER('SOME TEXT...');
SELECT LOWER([column_name]) FROM [table_name];

Practical example

To show how the LOWER() function works, we will use the following table:

MS SQL Server - example data used with LOWER() function
MS SQL Server - example data used with LOWER() function

Note:

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

Example

In this example, we will display all the names from users table in lowercase.

Query:

SELECT LOWER([name]) AS [Lowercase names] FROM [users];

Output:

MS SQL Server - LOWER() function result
MS SQL Server - LOWER() function result

Database preparation

create_tables.sql file:

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

 insert_data.sql file:

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