[b]Question asked by visitor indiradharmaraj[/b]
How many you are getting ?
It should be 6 I believe.
6 records will be retrieved. In this query outer join is used and there are six records where the dept id in both the tables are same, and the having clause says that only where the count of department is greater or equal to one.
