Failure to access Oracle data source with column names enclosed in double quotes -------------------------------------------------------------------------------- Key: TEIIDDES-1487 URL: https://issues.jboss.org/browse/TEIIDDES-1487 Project: Teiid Designer Issue Type: Bug Components: Teiid Integration Affects Versions: 7.4 Environment: EDS 5.2.0 Reporter: Hisanobu Okuda 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. For example, 1. create table and views as shown below in Oracle database {code} create table test(recno number, ref_no varchar2(4000)); create or replace view test_v as select recno as "Rec_Item_Number", ref_no as "bom_ref_no." from test; {code} 2. Import test_v data source view into JBoss developer studio 3. deploy and run the query against TEST_V:- Then, the following exception is thrown:- {code} 2012-09-05 08:34:39,386 WARN [org.teiid.CONNECTOR] (Worker0_QueryProcessorQueue13) Connector worker process failed for atomic-request=Imx1VPWhia7G.6.0.0 org.teiid.translator.jdbc.JDBCExecutionException: Error Code:1747 Message:'ORA-01747: invalid user.table.column, table.column, or column specification ' error executing statement(s): [Prepared Values: [] SQL: SELECT c_0, c_1 FROM (SELECT g_0.Rec_Item_Number AS c_0, g_0.bom_ref_no.
