Is there an easy way to determine if a given integer is not within a set of ranges of integers?  I have a table - tblRange with columns intStart and intEnd.  Each record in tblRange consists of records similar to this: intStart = 5, intEnd = 10; intStart = 1, intEnd = 6; intStart = 11, intEnd = 20, etc.  For each record, intStart is always >= intEnd and intStart >= 0.  Given n, how can determine if n does not lie within (inclusive) any of tblRange's records ranges?

SELECT *
FROM tblRange
WHERE n > intStart AND n < intEnd

If records are returned n is in that record's range.  if no records are returned it lies outside all the ranges.

Ah, I see inclusive, sorry:

SELECT *
FROM tblRange
WHERE n >= intStart AND n <= intEnd

   "intStart is always >= intEnd and intStart >= 0"

is that an error?

from your examples  intStart < intEnd.  not >=

can intStart be greater than intEnd?  can they be equal?
