If you are running out of SPOOL on SAMPLE and you are one release 4 you might use the RAMDOM function.

Sel * from table
where RANDOM(1,100) = 1;

This will only select rows when the random number generator returns a value of 1. This should be roughly 1% of the time. Then, if you needed a specific number of rows, combine the RANDOM with the SAMPLE. It will use less SPOOL and give you a random sample.
