Yes, an Gints' as well as mine deliberately omit the AS row for period 1. That is because the current solution wouldn't have it either. For period 1 it is simply a select a, b, year, 1, sum(amount) from test where year=blah and period <= 1 group by 1, b, year
so if there is no row for any a-b values for that year and period 1 it is not in the resultset.
The replacement solution should provide the same results. At 11:32 AM 10/31/2008, Gints Plivna wrote:
Yes because it wasn't also in Wolfgang's initially provided desired result set and is filtered out by WHERE alt_b IS NOT NULL. Anyway as I understood Wolfgang already succesfully solved his problem.
