The null part works correctly where the null value is stored in rec[0] and the field is marked as being null. However, when the 3 is processed, the 3 is places on rec[0] but the null flag is left uncleared. partition_range.result: Results block for bug #17894 partition_range.test: Test block for bug #17894 partition_list.result: Results block for bug #17173 partition_list.test: Test block for bug #17173 opt_range.cc: call set_notnull to clear any null flag that may have been set mysql-test/r/partition_range.result 1.7 06/03/13 14:45:35 rburnett@stripped +26 -0 Results block for bug #17894 mysql-test/t/partition_range.test 1.5 06/03/13 14:45:05 rburnett@stripped +27 -0 Test block for bug #17894 mysql-test/r/partition_list.result 1.4 06/03/13 14:43:53 rburnett@stripped +11 -0 Results block for bug #17173 mysql-test/t/partition_list.test 1.4 06/03/13 14:43:36 rburnett@stripped +14 -0 Test block for bug #17173 sql/opt_range.cc 1.205 06/03/13 14:42:38 rburnett@stripped +1 -0 call set_notnull to clear any null flag that may have been set # This is a BitKeeper patch.
