When using a subquery you need to get a single row back, so you're effectively doing a query for each record in the item table. UPDATE item i SET popularity = (SELECT SUM(io.quantity) FROM itemorder io WHERE io.item_id = i.item_id) > 3; An alternative (which is a postgresql extension) is...

Oh, this is a pain. Most databases do not support a product aggregation function. You can emulate it with logs and powers. So, something like this might work: select t.*, (select exp(sum(log(serial))) from table t2 where t2.no <= t.no ) as cumeProduct from table t; Note that log() might be...

Maybe this can get you started. I think it is what you expressed. However I think it would make more sense with an initialization like rnorm(nx,1,0.01) - i.e. something smoother.

I think it would be better to move the subquery to the from clause. Based on your logic, you are looking for joins, not left joins -- after all, the having clause is simply looking for any match. I think the following query does what you want: SELECT S.id, COUNT(dd.number)...

In Standard SQL you would use analytic functions for this.

There exists a rather simple O(n) approach using the so-called "two pointers" or "two iterators" approach. The key idea is to have two iterators (not necessarily C++ iterators, indices would do too) running on the same array so that if first iterator points to value x, then the second iterator...
