Additional info:
Documented bugfix in 5.1.9 changelog. Closed.
Description: DROP TABLE IF EXISTS t1; CREATE TABLE t1 (f_int1 INTEGER) PARTITION BY RANGE(f_int1) (PARTITION p1 VALUES LESS THAN (0), PARTITION p2 VALUES LESS THAN (10)); INSERT INTO t1 SET f_int1 = NULL ; SELECT * FROM t1; f_int1 NULL SELECT * FROM t1 WHERE f_int1 IS NULL; f_int1 <------ I miss the record. DROP TABLE t1; CREATE TABLE t1 (f_int1 INTEGER) PARTITION BY LIST(f_int1) (PARTITION p1 VALUES IN (0), PARTITION p2 VALUES IN (NULL)); INSERT INTO t1 SET f_int1 = NULL ; SELECT * FROM t1; f_int1 NULL SELECT * FROM t1 WHERE f_int1 IS NULL; f_int1 <--- I miss the record. My environment: - Intel PC with Linux(SuSE 9.3) - MySQL compiled from source Version 5.1 last ChangeSet@1.2142.24.2, 2006-03-08 I took S1/P1 because too many real simple SELECTs will suffer from this bug. How to repeat: Please use my attached testscript ml1116.test copy it to mysql-test/t echo "Dummy" > r/ml1116.result # Produce a dummy file with # expected results ./mysql-test-run ml1116
