Here is my table:
col1 col2
book1 author1
book1 author2
book1 author3
What I want to do is populated a drop down menu with each entry in col1 listed only once.
If I do this:
select col1 from table
then book1 gets listed 3 times.
So my question is how do I limit the number of values returned to 1 if the same value is returned more than once?
Thanks.
