Say I want to get:
0 0
0 1
0 2
1 0
1 1
1 2
etc
I'm to do (til 3) (,\:) til 3 but this doesn't seem to do it, giving me a type error.
What am I doing wrong?
How do I get all permutations in KDB?

cross keyword is what you are looking for
q)(til 3) cross til 3
0 0
0 1
0 2
1 0
1 1
1 2
2 0
2 1
2 2
The solution to your original problem without using a keyword is:
q)raze ((til 3),/:\:) til 3

0 1
0 2
1 0
1 1
1 2

2 1
