you can also enumerate on a keyed table for foreign keying
q)t:([a:“f”$1,2,3];b:1,2,3)
q)t1:(a:10?“f”$1,2,3;c:10?1) q)update t$a from t1 t1
q)show meta t1
| c | t f a |
|---|---|
| a | f t |
| c | s |
| q)select a,a.b,c from t1 where c=`j | |
| a b c |
1 1 j
1 1 j
but for vectors/atoms, only symbol types.
