[GENERAL] SELECT LIMIT and the last rows of a query

[mathprof]

The command:

SELECT (query) LIMIT m,n

gives m rows of the query's response, starting at row n+1, while

SELECT (query) LIMIT m

gives the first m rows of the query's response (starting at row 1).

Is there any easy way to get the *last* m rows of a query? I tried: 

SELECT (query) LIMIT 5, -5

in an attempt to get the last 5 rows, but this gives a parser error. Any
other thoughts?
