Hi,
is there a generic solution to dump the result of a query as a crosstab,
when I can't know how many columns I will need?
E.g. I get something like this:
id, x
1, a
1, b
1, c
2, l
2, m
and I'd like to see it as:
id, x1, x2, x3, ..... xn
1, a, b, c, null, .... null
2, l, m, ....
I fear the problem is I dont know n.
