Hi there,
Suppose you have a table:
id pos
1 (0,5)
2 (-1,6)
3 (5.5,9.8)
Are there functions to get to the individual coords such that
SELECT id,get_x(pos),get_y(pos) FROM table;
gives
id get_x get_y
1 0 5
2 -1 6
3 5.5 9.8
From doing a bit of snooping about in the Programmer's Guide, I can only
assume that this would involve a modified version point_out.
Are these functions already out there?
If not, can someone give me pointers to the answer?
Would the solution indeed be a modified version of point_out and if so, can
someone give me the point_out source to work with?
(I don't program in C -hell, I don't really program in anything, I dabble-
but I'm quite happy to experiment)
Regards,
Stuart.
