CREATE INDEX TMP_DATE1_IDX1 ON TMP_DATE1 COMPUTED BY (DATE1+0)

without index

SELECT count(*) FROM TMP_DATE1 T WHERE '01.03.2008' BETWEEN T.DATE1 AND T.DATE2;

count = 61

with index

SELECT count(*) FROM TMP_DATE1 T WHERE '01.03.2008' BETWEEN T.DATE1+0 AND T.DATE2

count = 1

Please provide PLANs generated for the statements.

Sean, this is a complete test case :-) You can see exactly the same plans as the reporter:

PLAN (TMP_DATE1 NATURAL) -- for the first query
and
PLAN (TMP_DATE1 INDEX(TMP_DATE1_IDX1)) -- for the second one

Moreover:

CREATE INDEX TMP_DATE1_IDX2 ON TMP_DATE1 (DATE1) ;

SELECT count(*) FROM TMP_DATE1 T WHERE '01.03.2008' BETWEEN T.DATE1 AND T.DATE2;
-- PLAN (TMP_DATE1 INDEX(TMP_DATE1_IDX2))
-- returns correct result (count == 61)

The simplified predicate which exposes the bug is:
WHERE '01.03.2008' >= T.DATE1

The problem is that the inverted boolean (literal compared to an indexed object) works correctly for an indexed field but fails for an indexed expression.
