Extracting Domain Name from Mail Address in SQL Server

Hello everyone,

In this article, I will give information about how to extract the domain name from the mail address in SQL Server.

In SQL Server, in some cases, you may want to reach the domain name from the e-mail address you have, that is, to obtain the domain information.

You can easily do this using the code below.

DECLARE @Table AS TABLE
(
    Email VARCHAR(100)
);

INSERT INTO @Table
(
    Email
)
SELECT 'y.selimkart@gmail.com'
UNION ALL
SELECT 'info@inovatifkimyadergisi.com'
UNION ALL
SELECT 'kim_muhselim@hotmail.com';


SELECT Email,
       SUBSTRING(Email, CHARINDEX('@', Email) + 1, LEN(Email) - CHARINDEX('@', Email)) Domain
FROM @Table
ORDER BY Email;

When you run the above code, you will see a result similar to the one below.

As you can see, we have removed the domain names from the e-mail address.

Good luck to everyone in business and life.
