As far as I can tell I am correctly updating the rows in the table but the Challenge Task keeps failing.

I have tried update phone_book set (first_name, last_name) = ('Mystery', 'Person');

AND

update phone_book set first_name = 'Mystery'; update phone_book set last_name = 'Person';

You're close, and your second try would actually work in practice. But the challenge wants you to to construct a single query that sets both values.

To set multiple values at a time, you can just separate them by commas. Here's a generic example:

UPDATE table SET field1 = value1, field2 = value2;

Thank you for the help. I could have sworn I tried that syntax originally but I guess not. Grouping with parentheses works in my IDE. Is it not correct syntax for SQLite?

That would also work in practice, I'm not sure why it doesn't pass the challenge. But it's probably not the technique that was shown in the videos.

I'd normally suggest submitting a bug report, but considering the recent changes, I suspect there's nobody to handle it.
