Description: CREATE TABLE t1 ( f_int1 INTEGER, f_int2 INTEGER, f_char1 CHAR(10), f_char2 CHAR(10), f_charbig VARCHAR(1000)) PARTITION BY LIST(MOD(f_int1,2)) SUBPARTITION BY HASH(f_int1) ( PARTITION part1 VALUES IN (0) , PARTITION part2 VALUES IN (1) , PARTITION part3 VALUES IN (2) ); DELETE FROM t1 WHERE f_int1 IS NULL OR f_int1 = 1; ERROR HY000: Lost connection to MySQL server during query Further experiments show that the crash disappears when - LIST(MOD(f_int1,2)) is replaced by LIST(f_int1) - SUBPARTITION BY HASH(f_int1) is omitted - IS NULL is replaced by = number - DELETE is replaced by SELECT - NDB is replaced by MyISAM That's the reason why I choosed Category: Cluster My environment: - Intel PC with Linux(SuSE 9.3) - MySQL compiled from source Version 5.1 last ChangeSet@1.2213, 2006-03-02 How to repeat: Please my attached testscript ndb_ml1105.test copy it to mysql-test/t echo "Dummy" > r/ndb_ml1105.result # Produce a dummy file with # expected results ./mysql-test-run ndb_1105 The script contains also the original testcase with a more reasonable partitioning scheme.
