Hi,
I have a couple of issues that I have been playing with for a project and can't quite get my head around it from a SQL POV.
Is it possible to list all the rows in a table where one column has more than one occurrence of the same value.
In this can I am storing the ip address of some submitted data, and I need to check to see if they have submitted more than 1 row. I don't care about the ones with a single occurance, but I need to know about the ones that appear more that one.
I think you're looking for something like:
SELECT foo, bar, count(baz) as num FROM table GROUP BY foo, bar HAVING num > 1;
Thanks, this will return the consolidated list of results, but is there a way to still display the individual details. I think I may need to create a new page that will help identify dups. Thanks again. Gordon
