What column am I missing from my query?

The question mentions there are only four columns in products: id, name, description and price. I included all four columns in my query and yet it returns with an error saying "You didn't select all columns". Can someone help point out which one I am missing?

Hi Joe,

Try selecting all of the columns with * instead of listing them all in your query.

When they ask for "all columns", it implies that you should use the "SELECT * " syntax which selects all columns without naming any explicitly.

Thanks guys, I realised instantly after I posted the question which was weird because the questions prior, I typed all the columns and that seemed to work.

Nethertheless a good lesson learned for the future.
