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
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
