Solution

Here is a SQL query that will give you the desired result:

SELECT owner_name, address, contact_number
FROM buildings
WHERE email_address IS NULL
ORDER BY owner_name ASC;

Here's a step-by-step breakdown of the query:

  1. SELECT owner_name, address, contact_number: This part of the query selects the columns that you want to display in your result. In this case, you want to display the owner's name, address, and contact number.

  2. FROM buildings: This part of the query specifies the table from which you want to retrieve the data. In this case, the table is buildings.

  3. WHERE email_address IS NULL: This is the condition that the rows must meet in order to be included in the result. In this case, you only want rows where the email_address is null, which means that the building does not have an email address.

  4. ORDER BY owner_name ASC: This part of the query sorts the result in ascending order by the owner_name. If you wanted to sort in descending order, you would use DESC instead of ASC.
