Hi there,
This is my problem now... I have a table containing different paths, like this:
+------+----+---+------------+
| Path | X | Y | WaypointNr |
+------+----+---+------------+
| P1 | 1 | 5 | 1 |
| P1 | 2 | 6 | 2 |
| P1 | 3 | 7 | 3 |
| P1 | 8 | 3 | 4 |
| P2 | 11 | 4 | 1 |
| P2 | 7 | 3 | 2 |
| P2 | 5 | 2 | 3 |
| P2 | 2 | 1 | 4 |
+------+----+---+------------+
I need to draw a map from these paths, so I make a following query to get waypoints
and paths located in defined area (where the corners are (3,2) and (7,6).
mysql> SELECT * FROM waypoints WHERE X > 2 AND X < 8 AND Y > 1 AND Y < 7;
+------+---+---+------------+
| Path | X | Y | WaypointNr |
+------+---+---+------------+
| P2 | 7 | 3 | 2 |
| P2 | 5 | 2 | 3 |
+------+---+---+------------+
That's OK... but now I would like to get also those waypoints which ones are next to
these results (on the same path). In this case, I want also points 1 and 4 on P2. How?
Emm... Hope that you could understand even something. ;)
