EmmyMiao87 opened a new issue #7823: URL: https://github.com/apache/incubator-doris/issues/7823
### 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 #6746 ### What's Wrong? The lateral view + subquery leads to the error join predicate ```equal join conjunct: `k3` = `k3` ``` ### What You Expected? Only one join predicate ```equal join conjunct: `k1` = `k3```` ### How to Reproduce? Steps: 1. create table ```CREATE TABLE `test_explode` ( `k1` int(11) NULL COMMENT "", `k2` varchar(1) NULL COMMENT "" ) ENGINE=OLAP DUPLICATE KEY(`k1`) COMMENT "OLAP" DISTRIBUTED BY HASH(`k1`) BUCKETS 5 PROPERTIES ( "replication_allocation" = "tag.location.default: 1", "in_memory" = "false", "storage_format" = "V2" ) ``` 2. query ```MySQL [test]> explain select k1 from test_explode lateral view explode_split(k2, ",") tmp as e1 where k1 in (select k3 from tbl1); +--------------------------------------------------------------------------------------+ | Explain String | +--------------------------------------------------------------------------------------+ | PLAN FRAGMENT 0 | | OUTPUT EXPRS:`k1` | | PARTITION: UNPARTITIONED | | | | RESULT SINK | | | | 6:EXCHANGE | | | | PLAN FRAGMENT 1 | | OUTPUT EXPRS: | | PARTITION: HASH_PARTITIONED: `k3`, `k1` | | | | STREAM DATA SINK | | EXCHANGE ID: 06 | | UNPARTITIONED | | | | 3:HASH JOIN | | | join op: LEFT SEMI JOIN (PARTITIONED) | | | hash predicates: | | | colocate: false, reason: The src data has been redistributed | | | equal join conjunct: `k3` = `k3` | | | equal join conjunct: `k1` = `k3` | | | runtime filters: RF000[in] <- `k3` | | | cardinality=-1 | | | | | |----5:EXCHANGE | | | | | 4:EXCHANGE | | | | PLAN FRAGMENT 2 | | OUTPUT EXPRS: | | PARTITION: HASH_PARTITIONED: `default_cluster:test`.`tbl1`.`k1` | | | | STREAM DATA SINK | | EXCHANGE ID: 05 | | HASH_PARTITIONED: `k3`, `k3` | | | | 2:OlapScanNode | | TABLE: tbl1 | | PREAGGREGATION: OFF.
