Correlated scalar subquery that uses count (x) aggregation is evaluated the same as count (1) and produces wrong results when 'x' has null values.

Ahead of Microsoft Build (and a possible SQL Server announcement), let's break down what we know and speculate about what we don't. One topic that has come up in several conversations with customers ...
