Question

I was just playing with adventureworks database in sqlserver. I got stuck in a query.
I wanted to Select all titles from HumanResources.Employee which are either ‘Male’ or ‘Female’ but not both.
i.e if title Accountant is Male and Female both I want to leave that title.
I need only those titles where Gender is either Male or Female.

I have done this till yet.

select distinct(title) from humanresources.employee where gender=’M’

select distinct(title) from humanresources.employee where gender=’F’

Probably a join between these two queries, would work. But If you have any other solution, please let me know.

It is not a homework. 🙂

Thanks in advance.

Here is the corrected version

select title from HumanResources.Employee as t
where gender='M' And Not Exists(select null from HumanResources.Employee as e
                        where gender='F' And e.title =t.title)
Union 

select title from HumanResources.Employee as t1
where gender='F' And Not Exists(select null from HumanResources.Employee as e1
                        where gender='M' And e1.title =t1.title)
order by title
