Hi,

I have a table that contains data keys similar the following, where each
letter is a key to an address



a,b
a,c
c,b
b,d
d,f
x,y
p,q

if i pass in a key such as "a" how can i return the items that are connected
to "a" both directly & indirectly?

I.E
a,b
a,c
c,b ( via a,c)
b,d (via a,b)
d,f ( via a,b+b,d)

the parent key is always in col1, the child in col2
