I don't understand what you're trying to do from your example. If you perform a cross on the data you have, the output will be the following:
(1,2,3,4,5,10,11) (1,2,3,4,5,10,11) (1,2,3,4,5,10,11) (1,2,4,5,7,10,11) (1,2,4,5,7,10,11) (1,2,4,5,7,10,11) (1,5,7,8,9,10,11) (1,5,7,8,9,10,11) (1,5,7,8,9,10,11) On this, you'll have to do a distinct to get what you're looking for. Let's change the example a little bit so we get a more clear understanding of your problem. What would be the output if your two relations looked as follows: (1,2,3,4,5) (10,11) (1,2,4,5,7) (10,12) (1,5,7,8,9) (10,13) On Tue, Mar 25, 2014 at 12:18 PM, Shahab Yunus <[email protected]>wrote: > Have you tried iterating over the first relation and in the nested > *generate* clause, always appending the second relation?
