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?

Challenge Task 3 of 3 Now we're using a database from a smartphone. It has a phone_book table. It has the columns id, first_name, last_name and phone.

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

Show the query you made from these instructions and perhaps we can help you figure out what's wrong.

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";

For future questions, please always start a fresh new question instead of adding a question onto an existing one.

But your query has two issues:

  • the table name in the task instructions is not "contacts " but "phone_book"
  • when joining conditions in a WHERE clause, instead of a comma use the word AND
