RE:performance tuning for query with 27 left joins - response (11) by blue

Can you help me understand why the queries below perform so differently? This query returned in 1 second: select count(*) from oeai3.v_dw_mbr_vers where mbr_key<200000000; row count = 8,951,890 This query failed with a spool space error: select count(*) from oeai3.v_dw_mbr_vers where mbr_key>200000000; This query also failed with a spool space error: select count(*) from oeai3.v_dw_mbr_vers;   Thanks.
