Failure to access Oracle data source with column names enclosed in double quotes -------------------------------------------------------------------------------- Key: TEIIDDES-1502 URL: https://issues.jboss.org/browse/TEIIDDES-1502 Project: Teiid Designer Issue Type: Bug Components: Import/Export Affects Versions: 7.7 Reporter: Hisanobu Okuda Assignee: Mark Drilling Priority: Minor Fix For: 8.2 EDS is throwing an error when accessing Oracle data source with column names enclosed in double quotes. I am able to import the metadata, test through Datasource explorer but when I run the query against VDB, it is not interpreting correctly to send double-quotes to the column name in this case, causing below error. {code} java.sql.SQLSyntaxErrorException: ORA-00922: missing or invalid option at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:445) at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:396) at oracle.jdbc.driver.T4C8Oall.processError(T4C8Oall.java:879) at oracle.jdbc.driver.T4CTTIfun.receive(T4CTTIfun.java:450) at oracle.jdbc.driver.T4CTTIfun.doRPC(T4CTTIfun.java:192) at oracle.jdbc.driver.T4C8Oall.doOALL(T4C8Oall.java:531) at oracle.jdbc.driver.T4CStatement.doOall8(T4CStatement.java:193) at oracle.jdbc.driver.T4CStatement.executeForRows(T4CStatement.java:1033) at oracle.jdbc.driver.OracleStatement.doExecuteWithTimeout(OracleStatement.java:1329) at oracle.jdbc.driver.OracleStatement.executeInternal(OracleStatement.java:1909) at oracle.jdbc.driver.OracleStatement.execute(OracleStatement.java:1871) at oracle.jdbc.driver.OracleStatementWrapper.execute(OracleStatementWrapper.java:318) at org.jboss.resource.adapter.jdbc.CheckValidConnectionSQL.isValidConnection(CheckValidConnectionSQL.java:58) at org.jboss.resource.adapter.jdbc.BaseWrapperManagedConnectionFactory.isValidConnection(BaseWrapperManagedConnectionFactory.java:560) at org.jboss.resource.adapter.jdbc.BaseWrapperManagedConnection.checkValid(BaseWrapperManagedConnection.java:364) at org.jboss.resource.adapter.jdbc.local.LocalManagedConnectionFactory.matchManagedConnections(LocalManagedConnectionFactory.java:402) at org.jboss.resource.connectionmanager.InternalManagedConnectionPool.getConnection(InternalManagedConnectionPool.java:225) at org.jboss.resource.connectionmanager.JBossManagedConnectionPool$BasePool.getConnection(JBossManagedConnectionPool.java:689) at org.jboss.resource.connectionmanager.BaseConnectionManager2.getManagedConnection(BaseConnectionManager2.java:404) at org.jboss.resource.connectionmanager.TxConnectionManager.getManagedConnection(TxConnectionManager.java:424) at org.jboss.resource.connectionmanager.BaseConnectionManager2.allocateConnection(BaseConnectionManager2.java:496) at org.jboss.resource.connectionmanager.BaseConnectionManager2$ConnectionManagerProxy.allocateConnection(BaseConnectionManager2.java:941) at org.jboss.resource.adapter.jdbc.WrapperDataSource.getConnection(WrapperDataSource.java:89) at org.teiid.translator.jdbc.JDBCExecutionFactory.getConnection(JDBCExecutionFactory.java:228) at org.teiid.translator.jdbc.JDBCExecutionFactory.getConnection(JDBCExecutionFactory.java:56) at org.teiid.translator.ExecutionFactory.getConnection(ExecutionFactory.java:184) at org.teiid.dqp.internal.datamgr.ConnectorWorkItem.execute(ConnectorWorkItem.java:207) at org.teiid.dqp.internal.process.DataTierTupleSource.getResults(DataTierTupleSource.java:354) at org.teiid.dqp.internal.process.DataTierTupleSource$1.call(DataTierTupleSource.java:143) at org.teiid.dqp.internal.process.DataTierTupleSource$1.call(DataTierTupleSource.java:140) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:303) at java.util.concurrent.FutureTask.run(FutureTask.java:138) at org.teiid.dqp.internal.process.DQPCore$FutureWork.run(DQPCore.java:120) at org.teiid.dqp.internal.process.DQPWorkContext.runInContext(DQPWorkContext.java:240) at org.teiid.dqp.internal.process.ThreadReuseExecutor$RunnableWrapper.run(ThreadReuseExecutor.java:122) at org.teiid.dqp.internal.process.ThreadReuseExecutor$3.run(ThreadReuseExecutor.java:292) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) {code} JDBC Importer should be identify this scenario and automatically enclose in double quotes, instead of we manually add double-quotes for these type of scenarios.
