The JOIN from Orders to OrderDetails meant that rows from the Orders table were duplicated, remember? So, if we SUM() a column in our Orders table when it is joined to the Details, we are summing up duplicate values and our result will be too high. In Part I of this two part series, we'll use a simple schema and a typical report request to cover the effect of JOINS on grouping and aggregate calculations, and how to use COUNT(Distinct) to overcome this
