Databases Modifying Data with SQL Deleting Data From a Database Deleting Data With SQL

I am failing to see where I am getting it wrong here?

Delete all contacts with the first name of Jonathan and last name of Luna,.

Without seeing your code all we can do is guess.

I'll guess that you might not have used two complete comparison expressions in your WHILE clause, or you may not have combined them with the AND keyword.

If I didn't manage to guess the issue, show your query code to make it possible to answer more accurately.

Can you help me? DELETE FROM contacts WHERE first_name = "Jonathan", last_name = "Luna";
