AliasSymbol wrapping AliasSymbol error -------------------------------------- Key: TEIID-3994 URL: https://issues.jboss.org/browse/TEIID-3994 Project: Teiid Issue Type: Bug Affects Versions: 8.7.1.6_2 Environment: Red Hat JBoss Data Virtualization 6.2 on EAP6.4.0 patched to version 6.4.3, JBoss Developer Studio 8.1.0GA with Teiid Designer plugin 9.0.3.Final.v20150810-1438-B1157 64-bit Windows 7 environment Reporter: Steve Tran Assignee: Steven Hawkins Fix For: 9.0, 8.12.5, 8.13.2 Attachments: Oracle.PNG, SQLServer.PNG I've defined a view and overrode the default triggers for Select, Insert, Update, and Delete. I overrode the triggers because the select is returning "hardcoded" values for a few fields (calling them virtual columns). The Update and Insert triggers will ignore these hardcoded values just in case the caller tries to update a virtual column. I'm trying to run a insert into <tableA> select * from <tableB> query. When I run this, I get an error org.teiid.jdbc.TeiidSQLException: Cannot create AliasSymbol wrapping AliasSymbol. Facts: -- I can insert a record if I only select one column from tableB. -- If I select two or more columns, it throws the error every time. -- If I remove the overridden triggers, the insert into <tableA> select * from <tableB> works fine. -- I can insert one or more columns into <tableA> when *not* using a insert into <tableA> select * from <tableB> query -- Table A is Oracle -- Table B is SQL Server My hunch is the generated query (hibernate, or whatever SQL generator) is choking with the overridden trigger. Perhaps this use-case slipped through testing, or even more probable, I made a mistake in the trigger creation. Here's a snip of the insert trigger, with a lot of fields removed for simplicity. {code} FOR EACH ROW BEGIN ATOMIC INSERT INTO <schema>.<tableA> (SourceSystemID, RecordTypeID, BatchID ...) VALUES ( convert("NEW".SourceSystemID, short), convert("NEW".RecordTypeID, short), convert("NEW".BatchID, integer) ... ) END {code}
