Re: combine this 2 simple querys into 1 query for performance.

There might be a simpler way but I think something like this could work...

SELECT * FROM ints;
+---+
| i |
+---+
| 0 |
| 1 |
| 2 |
| 3 |
| 4 |
| 5 |
| 6 |
| 7 |
| 8 |
| 9 |
+---+

SELECT i+(SELECT MAX(i) + i FROM ints)x,i FROM ints
UNION
SELECT i,i FROM ints
WHERE i > 7
ORDER BY x LIMIT 5;
+------+---+
| x    | i |
+------+---+
|    8 | 8 |
|    9 | 9 |
|    9 | 0 |
|   10 | 1 |
|   11 | 2 |
+------+---+
