[jira] [Created] (FLINK-22157) Join & Select a part of composite
primary key will cause ArrayIndexOutOfBoundsException
Caizhi Weng created FLINK-22157:
-----------------------------------
Summary: Join & Select a part of composite primary key will cause ArrayIndexOutOfBoundsException
Key: FLINK-22157
URL: https://issues.apache.org/jira/browse/FLINK-22157
Project: Flink
Issue Type: Bug
Components: Table SQL / Planner
Affects Versions: 1.13.0
Reporter: Caizhi Weng
Fix For: 1.13.0
Add the following test case to {{org.apache.flink.table.planner.plan.stream.sql.join.JoinTest}} to reproduce this bug.
{code:scala}
@Test
def myTest(): Unit = {
util.tableEnv.executeSql(
"""
|CREATE TABLE MyTable (
| pk1 INT,
| pk2 BIGINT,
| PRIMARY KEY (pk1, pk2) NOT ENFORCED
|) WITH (
| 'connector'='values'
|)
|""".stripMargin)
util.verifyExecPlan("SELECT A.a1 FROM A LEFT JOIN MyTable ON A.a1 = MyTable.pk1")
}
{code}
The exception stack is
{code}
java.lang.RuntimeException: Error while applying rule StreamPhysicalJoinRule, args [rel#141:FlinkLogicalJoin.LOGICAL.any.None: 0.[NONE].[NONE](left=RelSubset#139,right=RelSubset#140,condition==($0, $1),joinType=left), rel#138:FlinkLogicalCalc.LOGICAL.any.None: 0.[NONE].[NONE](input=RelSubset#137,select=a1), rel#121:FlinkLogicalTableSourceScan.LOGICAL.any.None: 0.[NONE].[NONE](table=[default_catalog, default_database, MyTable, project=[pk1]],fields=pk1)]
