Sort results based on two columns in specific order

[n1concepts]

Hi,

 

I need to sort a query 1st based on 'lb' column, then 'oz' column so that the results show - in DESC order from the 'paired' grouping of highest to lowest 'lb', 'oz' results.

Here'st the full requests showing all the weights from userid 3:

mysql> select lb,oz from tfish where userid = 3;
+----+----+
| lb | oz |
+----+----+
|  7 | 11 |
| 11 | 15 |
|  6 | 15 |
| 14 | 11 |
|  7 | 14 |
|  7 | 16 |
+----+----+
6 rows in set

Objective: I want to sort  on the highest weights and show them, descending, which should list in this order:
 

14, 11

 7,  16

 7,  14

 7,  11

=====

 

This is what I get on my query when attempting to order on highest 'lb' and in DESC with limit of 4:

Note: giving you more queries as well so you see the tabled info unfiltered:

mysql> select lb,oz from tfish where userid = 3 order by lb desc;
+----+----+
| lb | oz |
+----+----+
| 14 | 11 |
| 11 | 15 |
|  7 | 11 |
|  7 | 14 |
|  7 | 16 |
|  6 | 15 |
+----+----+
6 rows in set

mysql> select lb,oz from tfish where userid = 3 order by lb desc limit 4;
+----+----+
| lb | oz |
+----+----+
| 14 | 11 |
| 11 | 15 |
|  7 | 11 |
|  7 | 14 |
+----+----+
4 rows in set

mysql> 

Notice in the last query, 7, 16 is missing and 7,11 listed 1st  (7,16 should be listed as the 1st '7lb' reference b/c of 'oz' being 16, followed by 7lb 14 which then excludes 7lb 11oz from the query results.

 

Ok, (below) I'm providing the full table so you see everything - any help appreciated! (thx!)

mysql> select id,userid,lb,oz from tfish;
+----+--------+----+----+
| id | userid | lb | oz |
+----+--------+----+----+
|  1 |      3 |  7 | 11 |
|  2 |      3 | 11 | 15 |
|  3 |      1 |  5 | 11 |
|  4 |      3 |  6 | 15 |
|  5 |      3 | 14 | 11 |
|  6 |      3 |  7 | 14 |
|  7 |      1 |  5 |  4 |
|  8 |      3 |  7 | 16 |
+----+--------+----+----+
8 rows in set

Thanks - i knew I was missing something in the query syntax (works perfectly!)

mysql> select lb,oz from tfish where userid = 3 order by lb desc, oz desc limit 4;
+----+----+
| lb | oz |
+----+----+
| 14 | 11 |
| 11 | 15 |
|  7 | 16 |
|  7 | 14 |
+----+----+
4 rows in set
