[teiid-issues] [JBoss JIRA] Closed: (TEIID-1317) Limit keyword causes class cast exception running query against DB2 translator

Limit keyword causes class cast exception running query against DB2 translator ------------------------------------------------------------------------------ Key: TEIID-1317 URL: https://jira.jboss.org/browse/TEIID-1317 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 6.2.0, 7.0, 7.1 Reporter: Howard Abrams Assignee: Steven Hawkins Fix For: 7.1.1 When running a query that uses the limit keyword against a DB2 database/translator, teiid will throw the exception below (From the 7.1 codebase, but I got the same exception a while back playing with 7.0 as well as 6.2). The same query against the same schema in a different database (H2 for example) works fine. It appears it also works fin on DB2 if you leave off the starting rowing from the expression. Examples: /*works on H2*/ SELECT * FROM MYSCHEMA.FOO LIMIT 0,10 /*fails on DB2*/ SELECT * FROM MYSCHEMA.FOO LIMIT 0,10 /*fails on DB2*/ SELECT * FROM MYSCHEMA.FOO LIMIT 10,10 /*works on DB2*/ SELECT * FROM MYSCHEMA.FOO LIMIT 10 java.lang.ClassCastException: org.teiid.language.Function cannot be cast to org.teiid.language.Literal at org.teiid.dqp.internal.datamgr.LanguageBridgeFactory.translate(LanguageBridgeFactory.java:719) at org.teiid.dqp.internal.datamgr.LanguageBridgeFactory.translate(LanguageBridgeFactory.java:211) at org.teiid.dqp.internal.datamgr.LanguageBridgeFactory.translate(LanguageBridgeFactory.java:130) at org.teiid.dqp.internal.datamgr.ConnectorWorkItem.execute(ConnectorWorkItem.java:215) at org.teiid.dqp.internal.process.DataTierTupleSource.getResults(DataTierTupleSource.java:181) at org.teiid.dqp.internal.process.DataTierTupleSource.access$000(DataTierTupleSource.java:53) at org.teiid.dqp.internal.process.DataTierTupleSource$1.call(DataTierTupleSource.java:89) at org.teiid.dqp.internal.process.DataTierTupleSource$1.call(DataTierTupleSource.java:86) at org.teiid.dqp.internal.process.DQPCore$FutureWork.run(DQPCore.java:107) at org.teiid.dqp.internal.process.DQPWorkContext.runInContext(DQPWorkContext.java:188) at org.teiid.dqp.internal.process.ThreadReuseExecutor$RunnableWrapper.run(ThreadReuseExecutor.java:116) at org.teiid.dqp.internal.process.ThreadReuseExecutor$3.run(ThreadReuseExecutor.java:290) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:637)
