[web-devel] Yesod. Persistent. The little problem

[Max Cantor]

liftM2 (nub . (++)) (selectList [TableF1Eq v1, TableF2Eq v2] [] 0 0)
                    (selectList [TableF1Eq v1, TableF3Eq v2] [] 0 0)

its not very efficient, and mike will yell at me for using nub, but its good enough for 230 am.

goodnight, max
