Write a query to delete the details of the building whose owner got an email_address '[email protected]'.

Sure, here is a SQL query to delete the details of the building whose owner got an email_address '[email protected]'.

DELETE FROM Buildings
WHERE OwnerEmail = '[email protected]';

Please replace "Buildings" and "OwnerEmail" with your actual table name and column name.

Here are the steps:

1. Use the DELETE FROM statement in SQL to delete existing records in a table.
2. Specify the table name after the DELETE FROM statement. In this case, it's "Buildings".
3. Use the WHERE clause to filter records. It specifies which record(s) to delete. If you omit the WHERE clause, all records will be deleted!
4. Specify the condition after the WHERE clause. In this case, it's "OwnerEmail = '[email protected]'". It means we want to delete the records where the owner's email address is '[email protected]'.

Please note that this operation is irreversible. Once you delete the records, you cannot undo it. So, make sure you really want to delete these records.
