 Posted - 11/19/2013 :  11:41:49 I have a table of people: Name, City, Sex I want a table where each line is the city, and the number of Males and Females.For example, this is what I tried, and I know it's wrong:``` Select City, count(name) where Sex = 'M' as NumberM, count(name) where Sex = 'F' as NumberF Group by City ```how do I do this?Thanks.
