Is it possible to run a SQL query and depending on the result put a pool member up or down? The problem here is that the SQL query is not running against the pool member.

Yes. Both the MSSQL and MySQL monitors have fields where you can put an alias address (the address of the SQL server you want to check) and depending on whether the check is successful or not your pool member(s) will be marked UP/DOWN.

Thank you - I see those fields, but I don't have the ability to modify the field at least not from the monitor page. It just says : All Addresses All Ports

The only other way I can think of is to do an iRule. I have a pool which is not actually connected to the VS. Assign monitor to that pool. Then I could do an iRule which says, if MySqlServerPool has available members, then use this node, else use this other node. It is a bit of a hack... and seems unnecessary, but it would probably work. Please let me know if there is a cleaner way to do it.

  It looks like the fields are only editable when you create a new monitor for the first time . Once it has been created they cannot be modified.. That is what the problem was.

  The fields should be editable if you create a new monitor and do as Ngutierrez31 said (select the relevant SQL monitor as the parent).

  IT won't let me fill out the alias fields. They are not editable.
