You are correct. The example and db are at

Please provide a link where people can download your script.

You have an older beta version compiled under debug mode. The current version is 4.6.3. Try your solutions (RM#1 or RM#2) with Oracle on your 1.3 GHz desktop. Maybe it wouldn't be nearly twice slower than XDb1's solution running on a 5.6X slower 0.233 Ghz PocketPC. In addition, your solution is not as generic as XDb1's as it cannot handle the two case (and there are many more once) without redundant data and NULLs. Please improve your solution further.
