Summary: Accessing structured-types is not implemented by the runtime Key: CALCITE-2404 URL: https://issues.apache.org/jira/browse/CALCITE-2404 Project: Calcite Issue Type: Bug Components: core Affects Versions: 1.17.0 Reporter: Stamatis Zampetakis Assignee: Julian Hyde Queries on tables containing structured types cannot be executed by the Calcite runtime. A plan like the one that follows (taken from [CALCITE-2220|https://issues.apache.org/jira/browse/CALCITE-2220]) can be translated to neither Bindable nor EnumerableConvention. {noformat} LogicalProject(EXPR$0=[$0]) LogicalProject(EXPR$0$0=[ITEM($6, 1).EMPNO], EXPR$0$1=[ITEM($6, 1).ENAME], EXPR$0$2=[ITEM($6, 1).DETAIL]) LogicalProject(DEPTNO=[$0], NAME=[$1], TYPE=[$2.TYPE], DESC=[$2.DESC], A=[$2.OTHERS.A], B=[$2.OTHERS.B], EMPLOYEES=[$3]) LogicalTableScan(table=[[CATALOG, SALES, DEPT_NESTED]]) {noformat} More precisely, if a logical plan contains a RexFieldAccess expression that does not refer to a RexCorrelVariable it cannot be handled by the RexToLixTranslator. The translation will fail when calling [RexToLixTranslator#translate0|[https://github.com/apache/calcite/blob/5bbc501a565494442784f65870a20cd65a5016f4/core/src/main/java/org/apache/calcite/adapter/enumerable/RexToLixTranslator.java#L686]|https://github.com/apache/calcite/blob/5bbc501a565494442784f65870a20cd65a5016f4/core/src/main/java/org/apache/calcite/adapter/enumerable/RexToLixTranslator.java#L686].] -- This message was sent by Atlassian JIRA (v7.6.3#76005)
