I'm trying to get some 'release/version numbers' to sort properly.
mysql> SELECT ReleaseID, Name FROM releases ORDER BY Name DESC;
+-----------+---------------------+
| ReleaseID | Name |
+-----------+---------------------+
| 18 | Unspecified |
| 20 | Next Patch |
| 58 | LOCset |
| 74 | Abashiri |
| 54 | 4.6.0 (Folsom) |
<-- 4.5.10 should be here
| 99 | 4.5.9 |
| 98 | 4.5.6 |
| 93 | 4.5.5 (Purdy) |
| 97 | 4.5.4 |
| 96 | 4.5.3 |
| 94 | 4.5.2 |
| 100 | 4.5.10 | <-- should be ^ there
| 91 | 4.5.1 Deferred |
| 78 | 4.5.1 (Leavenworth) |
| 95 | 4.2.7.4 |
| 92 | 4.2.7.3 |
| 90 | 4.2.7.2 |
| 87 | 4.2.7.1 |
| 88 | 4.2.7.0 |
I like this order, especially with the top four,
except for that 4.5.10 should be higher up,
just under 4.6.0, not under 4.5.2 as it is now.
So I tried the " + 0 " trick which makes things even worse
(notice the 4.2.6.1 and 4.2.6.0 -- yipes!):
mysql> SELECT ReleaseID, Name FROM releases ORDER BY Name + 0 DESC;
+-----------+---------------------+
| ReleaseID | Name |
+-----------+---------------------+
....(18,20,58,74) are moved
:(
| 54 | 4.6.0 (Folsom) |
| 78 | 4.5.1 (Leavenworth) |
| 100 | 4.5.10 |
| 91 | 4.5.1 Deferred |
| 93 | 4.5.5 (Purdy) |
| 94 | 4.5.2 |
| 96 | 4.5.3 |
| 97 | 4.5.4 |
| 98 | 4.5.6 |
| 99 | 4.5.9 |
| 82 | 4.2.6.1 | << ?
| 76 | 4.2.2 |
| 75 | 4.2.4 |
| 72 | 4.2.1 |
| 73 | 4.2.3 |
| 67 | 4.2.6.0 | << ?
I'm pretty sure this is going to involve some sort of splitting the version
from the release codeword via some string functions, and then operating on
that part.
