My experienced mainframe DB2 colleagues have warned me that coding the predicate "WHERE part_no IS BETWEEN :foo
AND :bar" is less efficient than "WHERE part_no >= :foo AND <= :bar"
Is there truly a performance difference?
With DB2 UDB for iSeries there is no performance difference between the BETWEEN predicate and its logic equivalent.
