9. Delete
If we want to delete a row we must use the combination of words DELETE FROM + the name of the table + a filter.
DELETE FROM [tabla] WHERE [condicionales];
Let's delete a row from Playlist, the one called Audiobooks.
DELETE FROM Playlist WHERE Name = 'Audiobooks';
Or, if we want to be more specific, with its Id.
DELETE FROM Playlist WHERE PlaylistId = 6;
If you do not use
WHERE, you will delete all the information in the table!
Activity 1

Tracktable.
