First does this table have a PK ?
The thing is I thought that the theory is that SQL engine doesn't give a monkey's
ass (or monkey's tits) about the "order" of the placement of the rows in the result set so hard part for me is: how can you guarrantee yourself that row(x) should get the updates from row(x+1) ? ie how do you define the relationship btw row(x) and row(x+1) ?
