ORDER BY and UNION fails ------------------------ Key: TEIID-2963 URL: https://issues.jboss.org/browse/TEIID-2963 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 8.7, 8.8 Reporter: Tom Arnold Assignee: Steven Hawkins Labels: oracle, order, select, union I can reproduce this in Teiid 8.7.0.Final and nightly build from master (09e396f). The same query works fine when performed directly against Oracle. {code:sql} select "FOO"."FOO_ID" "FOO_ID" from ( (select "ITEMS"."ITEM_ID" "FOO_ID" from "BLAH"."ITEMS" "ITEMS" group by "ITEMS"."ITEM_ID") union all (select "ITEMS"."ITEM_ID" "FOO_ID" from "BLAH"."ITEMS" "ITEMS") ) "FOO" order by "FOO_ID" desc; {code} {code} 03:47:21,218 WARN [org.teiid.CONNECTOR] (Worker7_QueryProcessorQueue189) 6w9Z3uBcAONA Connector worker process failed for atomic-request=6w9Z3uBcAONA.8.1.39: org.teiid.translator.jdbc.JDBCExecutionException: 904 TEIID11008:TEIID11004 Error executing statement(s): [Prepared Values: [] SQL: SELECT g_1."ITEM_ID" AS c_0 FROM "BLAH"."ITEMS" g_1 GROUP BY g_1."ITEM_ID" UNION ALL SELECT g_0."ITEM_ID" AS c_0 FROM "BLAH"."ITEMS" g_0 ORDER BY FOO_ID DESC] at org.teiid.translator.jdbc.JDBCQueryExecution.execute(JDBCQueryExecution.java:131) at org.teiid.dqp.internal.datamgr.ConnectorWorkItem.execute(ConnectorWorkItem.java:326) [teiid-engine-8.8.0.Alpha2-SNAPSHOT.jar:8.8.0.Alpha2-SNAPSHOT] at org.teiid.dqp.internal.process.DataTierTupleSource.getResults(DataTierTupleSource.java:298) [teiid-engine-8.8.0.Alpha2-SNAPSHOT.jar:8.8.0.Alpha2-SNAPSHOT] at org.teiid.dqp.internal.process.DataTierTupleSource$1.call(DataTierTupleSource.java:110) [teiid-engine-8.8.0.Alpha2-SNAPSHOT.jar:8.8.0.Alpha2-SNAPSHOT] at org.teiid.dqp.internal.process.DataTierTupleSource$1.call(DataTierTupleSource.java:107) [teiid-engine-8.8.0.Alpha2-SNAPSHOT.jar:8.8.0.Alpha2-SNAPSHOT] at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:334) [rt.jar:1.7.0_02] at java.util.concurrent.FutureTask.run(FutureTask.java:166) [rt.jar:1.7.0_02] at org.teiid.dqp.internal.process.FutureWork.run(FutureWork.java:58) [teiid-engine-8.8.0.Alpha2-SNAPSHOT.jar:8.8.0.Alpha2-SNAPSHOT] at org.teiid.dqp.internal.process.DQPWorkContext.runInContext(DQPWorkContext.java:274) [teiid-engine-8.8.0.Alpha2-SNAPSHOT.jar:8.8.0.Alpha2-SNAPSHOT] at org.teiid.dqp.internal.process.ThreadReuseExecutor$RunnableWrapper.run(ThreadReuseExecutor.java:119) [teiid-engine-8.8.0.Alpha2-SNAPSHOT.jar:8.8.0.Alpha2-SNAPSHOT] at org.teiid.dqp.internal.process.ThreadReuseExecutor$3.run(ThreadReuseExecutor.java:214) [teiid-engine-8.8.0.Alpha2-SNAPSHOT.jar:8.8.0.Alpha2-SNAPSHOT] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) [rt.jar:1.7.0_02] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) [rt.jar:1.7.0_02] at java.lang.Thread.run(Thread.java:722) [rt.jar:1.7.0_02] Caused by: java.sql.SQLSyntaxErrorException: ORA-00904: "FOO_ID": invalid identifier at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:450) at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:399) at oracle.jdbc.driver.T4C8Oall.processError(T4C8Oall.java:1017) at oracle.jdbc.driver.T4CTTIfun.receive(T4CTTIfun.java:655) at oracle.jdbc.driver.T4CTTIfun.doRPC(T4CTTIfun.java:249) at oracle.jdbc.driver.T4C8Oall.doOALL(T4C8Oall.java:566) at oracle.jdbc.driver.T4CPreparedStatement.doOall8(T4CPreparedStatement.java:215) at oracle.jdbc.driver.T4CPreparedStatement.doOall8(T4CPreparedStatement.java:58) at oracle.jdbc.driver.T4CPreparedStatement.executeForDescribe(T4CPreparedStatement.java:776) at oracle.jdbc.driver.OracleStatement.executeMaybeDescribe(OracleStatement.java:897) at oracle.jdbc.driver.OracleStatement.doExecuteWithTimeout(OracleStatement.java:1034) at oracle.jdbc.driver.OraclePreparedStatement.executeInternal(OraclePreparedStatement.java:3820) at oracle.jdbc.driver.OraclePreparedStatement.executeQuery(OraclePreparedStatement.java:3867) at oracle.jdbc.driver.OraclePreparedStatementWrapper.executeQuery(OraclePreparedStatementWrapper.java:1502) at org.jboss.jca.adapters.jdbc.WrappedPreparedStatement.executeQuery(WrappedPreparedStatement.java:462) at org.teiid.translator.jdbc.JDBCQueryExecution.execute(JDBCQueryExecution.java:123) ... 13 more {code}
