<!-- We test rewriting sum(), avg(), count() to a single call of sumCount() here.
|
|
As a reference, we use the same queries with the optimization disabled.
|
|
sum() has a highly optimized algorithm, so alone it will be faster than sumCount(),
|
|
but when we add count() or avg(), the sumCount() should win.
|
|
Also test GROUP BY with and without keys, because they might have different
|
|
optimizations. -->
