Hi,

It would be very nice to have option, to add additional action in case if database monitor query (via ODBC) returns empty result.

Before "databse monitor" item I was monitoring Oracle with Orabbix which did this job by himself substituting empty results with "none", "empty", FALSE, or whatever else.

Now when I have switched to monitoring databases with ODBC, it's not always trivial to manipulate selects so they will return single value "none" instead of empty result especially when it's empty, multi-column result.
