Can you just do another query, joining on the two columns?

it could be optomized a tiny bit if both arrays are sorted
if your looking through the second array for something beginning with
"a",
when you get to "b"'s you know your done (:

Like maybe looping through one and comparing each to the rows in the
other
and if there is no match, add a row to a new array
Could get slow if the arrays are big.

@union gives you all rows from both arrays. He wants array
"difference",
which doesn't exist. :(

Hi All
I have 2 arrays with 2 columns each. What I need to do is is make a
new
array containing only the rows that are not the same in the 2
arrays.
Any ideas would be great.
