how to group by and count using MySQL

Question

I have data which looks like this:

ID  post_author post_title  guid
3309    21  Should somebody not yet on SQL 2008 wait for SQL 2008 R2, since it\'s near release?  h         


        

Answer 1

It may be possible to construct such a query but will be not optimized.

You should add a column to your table which will have an ID of the site. Then add a new table which will have a preparsed data for the site: domain, path, resource, whether http or https, etc

This way you can be more flexible in searches and will be much faster, since I assume you have few inserts and large number of reads.
