Long should be plenty. Maximum value is 9223372036854775807, so even stepping
through 1000 at a time it will take about 9223372036854775 requests to hit
that. Assuming (very generously) 1 millisecond per request that's 292,277 years.
How are you creating the query, and incrementing x? The parser is seeing a
decimal, which could simply be an error creating the query.
