Bug # 17894 - Comparison with "less than" operator fails with range partition The problem here was that on queries such as < 3, the range given is NULL < n < 3. 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 sql/opt_range.cc: call set_notnull to clear any null flag that may have been set mysql-test/t/partition_list.test: Test block for bug #17173 mysql-test/r/partition_list.result: Results block for bug #17173 mysql-test/t/partition_range.test: Test block for bug #17894 mysql-test/r/partition_range.result: Results block for bug #17894
