kangkaisen opened a new pull request #344: Fix worng query result when column value is Null
URL: https://github.com/apache/incubator-doris/pull/344
Fix [343](https://github.com/apache/incubator-doris/issues/343)
The root cause for [343](https://github.com/apache/incubator-doris/issues/343) is ScanKey is wrong.
```
I1122 18:12:51.577086 21470 olap_scan_node.cpp:380] BuildScanKey
I1122 18:12:51.579259 21470 olap_common.h:200] ScanKeys:
I1122 18:12:51.579268 21470 olap_common.h:203] ScanKey=[3001,3,-128,1090050 : 3001,3,-128,1090050]
I1122 18:12:51.579274 21470 olap_common.h:203] ScanKey=[3001,3,-127,1090050 : 3001,3,-127,1090050]
I1122 18:12:51.579279 21470 olap_common.h:203] ScanKey=[3001,3,-126,1090050 : 3001,3,-126,1090050]
I1122 18:12:51.580550 21470 olap_common.h:203] ScanKey=[3001,3,126,1090050 : 3001,3,126,1090050]
I1122 18:12:51.580555 21470 olap_common.h:203] ScanKey=[3001,3,127,1090050 : 3001,3,127,1090050]
```
So we should add null to ScanKey when ColumnValueRange convert_to_fixed_value.
I will add a test case to olap_common_test tomorrow
