Ruben Q L created CALCITE-3484: ---------------------------------- Summary: SqlToRelConverter: ClassCastException when processing a query with ANY and UNNEST Key: CALCITE-3484 URL: https://issues.apache.org/jira/browse/CALCITE-3484 Project: Calcite Issue Type: Bug Affects Versions: 1.21.0 Reporter: Ruben Q L
The problem can be reproduced by adding the following test to SqlToRelConverterTest.java: {code} @Test public void testEqAnyUnnest() { final String sql = "select d.deptno from dept_nested d WHERE 'john' = ANY (SELECT e.ename from UNNEST(d.employees) e)"; sql(sql).ok(); } {code} Which throws the following exception: {code} java.lang.ClassCastException: org.apache.calcite.rel.logical.LogicalCorrelate cannot be cast to org.apache.calcite.rel.core.Join at org.apache.calcite.sql2rel.SqlToRelConverter.translateIn(SqlToRelConverter.java:1285) at org.apache.calcite.sql2rel.SqlToRelConverter.substituteSubQuery(SqlToRelConverter.java:1157) at org.apache.calcite.sql2rel.SqlToRelConverter.replaceSubQueries(SqlToRelConverter.java:1013) at org.apache.calcite.sql2rel.SqlToRelConverter.convertWhere(SqlToRelConverter.java:979) at org.apache.calcite.sql2rel.SqlToRelConverter.convertSelectImpl(SqlToRelConverter.java:648) at org.apache.calcite.sql2rel.SqlToRelConverter.convertSelect(SqlToRelConverter.java:626) at org.apache.calcite.sql2rel.SqlToRelConverter.convertQueryRecursive(SqlToRelConverter.java:3180) at org.apache.calcite.sql2rel.SqlToRelConverter.convertQuery(SqlToRelConverter.java:562) at org.apache.calcite.test.SqlToRelTestBase$TesterImpl.convertSqlToRel(SqlToRelTestBase.java:626) at org.apache.calcite.test.SqlToRelTestBase$TesterImpl.assertConvertsTo(SqlToRelTestBase.java:745) at org.apache.calcite.test.SqlToRelConverterTest$Sql.convertsTo(SqlToRelConverterTest.java:3664) at org.apache.calcite.test.SqlToRelConverterTest$Sql.ok(SqlToRelConverterTest.java:3656) at org.apache.calcite.test.SqlToRelConverterTest.testEqAnyUnnest(SqlToRelConverterTest.java:1266) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:50) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:47) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:325) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:78) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:57) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.junit.runner.JUnitCore.run(JUnitCore.java:137) at com.intellij.junit4.JUnit4IdeaTestRunner.startRunnerWithArgs(JUnit4IdeaTestRunner.java:68) at com.intellij.rt.execution.junit.IdeaTestRunner$Repeater.startRunnerWithArgs(IdeaTestRunner.java:47) at com.intellij.rt.execution.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:242) at com.intellij.rt.execution.junit.JUnitStarter.main(JUnitStarter.java:70) {code} Note that the following "similar" queries are correctly converted: {code} @Test public void testUnnestEq() { final String sql = "select d.deptno from dept_nested d, UNNEST(d.employees) e WHERE e.ename = 'john'"; sql(sql).ok(); } @Test public void testInUnnest() { final String sql = "select d.deptno from dept_nested d WHERE 'john' IN (SELECT e.ename from UNNEST(d.employees) e)"; sql(sql).ok(); } @Test public void testExistsUnnest() { final String sql = "select d.deptno from dept_nested d WHERE EXISTS (SELECT 1 from UNNEST(d.employees) e WHERE e.ename = 'john')"; sql(sql).ok(); } {code} -- This message was sent by Atlassian Jira (v8.3.4#803005)
