Let me assume this: we have two tables, one is Regions table with all region information (East, West, etc. ) and we have another table with Sales information. Now, we need to display a report with region information and how many sales conducted in each region with greater than $1000 value in each sale. It sounds simple at the beginning since a Count(*) with Group By can do this trick.
But what if I need to still show the region which does not have any sales greater than $1000 on the report? Using Count(*) itself in the query, the region without any sales greater than $1000 will not show in the query result, period.
