How to display names who use particular mail sql

To display names of users who use a particular email address in a SQL database, you can use a query that joins the users table with the emails table (assuming you have separate tables for users and emails).

Here's an example query:

SELECT u.name
FROM users u
JOIN emails e ON u.id = e.user_id
WHERE e.email = '[email protected]';

This query assumes that:

• The users table has a column named id that uniquely identifies each user.
• The emails table has a column named user_id that references the id column in the users table.
• The emails table has a column named email that stores the email address.

The query joins the users table with the emails table on the user_id column, and then filters the results to only include rows where the email column matches the desired email address.

You can modify the query to use a different column name or table name if needed.

For example, if your table names are users_table and email_table, and the column names are user_id and email_address, you can use the following query:

SELECT ut.name
FROM users_table ut
JOIN email_table et ON ut.user_id = et.user_id
WHERE et.email_address = '[email protected]';

If you want to display all the email addresses associated with a particular user, you can use a query like this:

SELECT e.email
FROM users u
JOIN emails e ON u.id = e.user_id
WHERE u.name = 'John Doe';

This query joins the users table with the emails table on the user_id column, and then filters the results to only include rows where the name column in the users table matches the desired name.

You can modify the query to use a different column name or table name if needed.
