In my case (not being an administrator, or maybe it's just our new SQL 2005 database) the master.sys.columns only has 44 rows, and the query only supplies 85,184 rows (44 cubed).

If it had only 3 more rows it would have reached the 100,000 mark.

But using the INFORMATION_SCHEMA.COLUMNS view with 4140 rows worked fine, and would give up to 70,000,000,000 consecutive numbers.
