Examples 4, 5, 12, 39, 117, 121, 123, 133, 139, etc at www.dbfordummies.com/example/default.asp might be considered swamp-like by some. In past discussions, you have agreed that example 12 might be too swampish for RMDBs, yet it is easy to navigate with dbd. Or could you specify a new swamp and a basic query that should demonstrate inability to make the right turns? Received on Thu Jun 22 2006 - 21:30:06 CDT
