Question : Nested Subquery efficiency

Harfang showed me the light with subqueries, then I quickly drowned myself with them using nested subqueries.
Basically these 2 queries sum up the points per event teamAbbrev rank them, then assign points based on that rank.

The problem is, the 2nd query I have listed, which is used in the first query takes about 5seconds to run. The 1st query takes somewhere around 10minutes. And currently I have 1/5 of the data that there will be.

How can I make this faster? I have indexed every field that was relevant, and all field data types are the best they can be.

Answer : Nested Subquery efficiency

I thought count() was optimized to be faster than a count on a field. There will be a lot of nulls, like 75% are going to be null, and won't be found in tblPts

I changed the to one of the fields in the query that doesn't have nulls, but it was still more than a 1min to query, then I canceled it.

I'm going to try making the subquery a MakeTable, and querying that.
