hello, you can not simultaneously fix two deamons to a data directory. a
mysql daemon always has exclusive access to the data directory.

Yups. If you want to have two active servers, you'll need to set up
master-master replication and give each server it's own datastore. Note that
there's a load of caveats if you want to write to both servers, though -
read up on the documentation.

Thanks Guys for you insights.
It may be a little more complicated then I made it out to be.
I have tried this select substring_index(myfiled,'.',-2) from mytable.
This has gotten me to a good starting point.
But I still have two problems. After the extension there is a space
and more wording.

I am just trying to pull out the file extension but there were some
conditions I did not list.

Thank you for that update, would have been good to have from the start.

Sorry Jay,
Here is what I came up with.
select substring(substring_index(myfile,'.',-2),1,4) AS MyColumn from
mydatabase group by MyColumn;
That appears to yield what I need. I just need to filter out the
results that do not have an extension.

Usually, you better use a NAS for such purpose. Database is designed
to store highly transactional, record oriented storage that needs fast
access... You can look for any Enterprise content management systems
that rest its storage on a scalable NAS, with file virtualization in
the long run.
