Subject:Re: DISTINCT and COUNT() SQL Query
View as plain text  
Yes! I want the number of distinct names. None of the earlier queries give me
what I'm looking for. I want the number of distinct names in the same way as
a 'select count(*) from names' would, exept that would give me all the
entries (count the same name multiple times).
