In this article, we would like to show you how to use AND, OR and NOT operators in MS SQL Server.

To show how the mentioned operators work, we will use the following table:

MS SQL Server - example data used with AND, OR, NOT operators

Note:

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

AND

Edit

Syntax:

xxxxxxxxxx
 
SELECT [column1], [column2], ...
FROM [table_name]
WHERE condition1 AND condition2 AND condition3 ...;

Practical example

Edit

In this example, we will display information about users with specified department_id AND salary greater than 1400$.

Query:

xxxxxxxxxx
 
SELECT * FROM [users]
WHERE [department_id] = 2 AND [salary] > 1400;

Output:

MS SQL Server - SELECT with AND operator result

OR

Edit

Syntax:

xxxxxxxxxx
 
SELECT [column1], [column2], ...
FROM [table_name]
WHERE condition1 OR condition2 OR condition3 ...;

Practical example

Edit

In this example, we will display information about users whose name is Kate OR Simon.

Query:

xxxxxxxxxx
 
SELECT * FROM [users]
WHERE [name] = 'Kate' OR [name] = 'Simon';

Output:

MS SQL Server - SELECT with OR operator result

NOT

Edit

Syntax:

xxxxxxxxxx
 
SELECT [column1], [column2], ...
FROM [table_name]
WHERE NOT condition;

Practical example

Edit

In this example, we will display information about users whose department_id is NOT 2.

Query:

xxxxxxxxxx
 
SELECT * FROM [users]
WHERE NOT [department_id] = 2;

Output:

MS SQL Server - SELECT with NOT operator result

Database preparation

Edit

create_tables.sql file:

xxxxxxxxxx
 
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:

xxxxxxxxxx
 
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');
