EmmyMiao87 opened a new issue, #10342:
URL: https://github.com/apache/doris/issues/10342
### Search before asking
- [X] I had searched in the [issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and found no similar issues.
### Version
Doris 1.1
### What's Wrong?
The incorrect predicate inference leads to wrong results.
### What You Expected?
Without incorrect predicate inference.
### How to Reproduce?
1. create table
```
CREATE TABLE `test` (
`k1` tinyint(4) NULL COMMENT "",
`k2` smallint(6) NULL COMMENT "",
`k3` int(11) NULL COMMENT "",
`k4` bigint(20) NULL COMMENT "",
`k5` decimal(9, 3) NULL COMMENT "",
`k6` char(5) NULL COMMENT "",
`k10` date NULL COMMENT "",
`k11` datetime NULL COMMENT "",
`k7` varchar(20) NULL COMMENT "",
`k8` double MAX NULL COMMENT "",
`k9` float SUM NULL COMMENT ""
) ENGINE=OLAP
AGGREGATE KEY(`k1`, `k2`, `k3`, `k4`, `k5`, `k6`, `k10`, `k11`, `k7`)
COMMENT "OLAP"
DISTRIBUTED BY HASH(`k1`) BUCKETS 5
PROPERTIES (
"replication_allocation" = "tag.location.default: 1",
"in_memory" = "false",
"storage_format" = "V2"
)
```
```
CREATE TABLE `baseall` (
`k1` tinyint(4) NULL COMMENT "",
`k2` smallint(6) NULL COMMENT "",
`k3` int(11) NULL COMMENT "",
`k4` bigint(20) NULL COMMENT "",
`k5` decimal(9, 3) NULL COMMENT "",
`k6` char(5) NULL COMMENT "",
`k10` date NULL COMMENT "",
`k11` datetime NULL COMMENT "",
`k7` varchar(20) NULL COMMENT "",
`k8` double MAX NULL COMMENT "",
`k9` float SUM NULL COMMENT ""
) ENGINE=OLAP
AGGREGATE KEY(`k1`, `k2`, `k3`, `k4`, `k5`, `k6`, `k10`, `k11`, `k7`)
COMMENT "OLAP"
DISTRIBUTED BY HASH(`k1`) BUCKETS 5
PROPERTIES (
"replication_allocation" = "tag.location.default: 1",
"in_memory" = "false",
"storage_format" = "V2"
)
```
3. query
```
select a.k1, b.k1, a.k2, b.k2, a.k3, b.k3 from test a , baseall b where a.k1 = b.k1 and a.k2 > b.k2 and a.k2 > 0 and b.k3 != 0 and a.k6 > "000" order by 1, 2, 3, 4, 5 limit 65535
```
4. the incorrect ```b.k2 > 0 ``` could not be inference.
