Simple SQL-query

I have one table with +500K records. The records consist of transactions.


12 December 2011 +1

14 December 2011 +4

18 December 2011 -1

For someone who can do this, this is pretty easy. I need someone today who can create query that makes able to select a period and and merge these transactions to 1 transaction for all the users within that period. So above becomes one record called Archive with +5.

This also needs to be done today. So if you bid, make sure to start right away.

Stupid of..+4 of course.. ;-)
