1,776 PointsA little Lost what am i missing
SELECT ratings, MAX(rating) AS "star_max", MIN(rating) AS "star_min" FROM reviews ORDER BY ratings;

- the table has no "ratings" (plural) field, and the instructions only asked for min and max
- you won't need ORDER BY
- you will need a WHERE clause to limit the calculations to just "Star Man" ratings

Derek Morse
1,776 PointsSELECT rating FROM reviews WHERE ID =6 MAX(rating) AS "star_max", MIN(rating) AS "star_min";
it is still off i seem to be missing somehting i am just not seeing;
Steven Parker
240,995 PointsThe functions and aliases need to be in the SELECT clause (as you had originally). And as I mentioned before, you'll want to test "movie_id" instead of "ID".
Derek Morse
1,776 PointsSELECT rating FROM reviews WHERE "movie_id" = 6, MAX(rating) AS "star_max", MIN(rating) AS "star_min"
i see what you are saying but i think there is one piece missing.
Steven Parker
240,995 PointsThe functions and aliases still need to be in the SELECT clause (as you had originally), but rating by itself does not. And movie_id should not be in quotes.

1,776 PointsSELECT rating FROM reviews WHERE movie_id = 6 MAX(rating) AS "star_max", MIN(rating) AS "star_min";
Steven Parker
240,995 PointsI think we have a misunderstanding of the terms. To be clear, when I talk about the "SELECT clause", I mean the area after the word SELECT but before FROM.
And "rating" should not be there, but the functions and aliases should (as in your very first example).
Derek Morse
1,776 PointsSELECT rating FROM reviews, MAX(rating) AS "star_max", MIN(rating) AS "star_min" WHERE movie_id =6; still wrong
Derek Morse

240,995 PointsAs I mentioned before, the instructions only asked for min and max (not "rating" itself). And a WHERE clause always comes after the FROM clause. And you'll want to test "movie_id" instead of "ID".

1,776 PointsSELECT rating FROM reviews WHERE movie_id = 6 MAX as "star_max" AND MIN as "star_min"; i still get an error most like gonna a take a break for a while

240,995 PointsThe original code you started with had a closer SELECT clause, the min and max functions and aliases were fine but the "ratings" just didn't need to be there.
