Subject: [nycphp-talk] OT - MySQL select question
Greetings,
I'm not sure how to do the following, any tips?
I have a column in a MySQL table that contains varchars. I would like
to select all records where there are instances of more than one record
for any given varchar.
So in plain language, the SQL statement would look something like:
select * from table where the occurence of each unique varchar in column
A is greater than one.
Thoughts? Thanks!
-Aaron
