[teiid-issues] [JBoss JIRA] (TEIID-2479) Selecting from SYS model throws exception

Selecting from SYS model throws exception ----------------------------------------- Key: TEIID-2479 URL: https://issues.jboss.org/browse/TEIID-2479 Project: Teiid Issue Type: Bug Affects Versions: 7.4 Environment: Teiid 8.3 running in JBoss EAP 6.0 RPM install java version "1.7.0_09-icedtea" OpenJDK Runtime Environment (rhel-2.3.8.0.el6_4-x86_64) OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode) Reporter: Graeme Gillies Assignee: Steven Hawkins Fix For: 8.4 We have a dynamic vdb deployed into our Teiid 8.3 environment, but whenever we connect to the vdb via the pgsql emulation socket using the standard postgresql tools, and attempt to select any value from any tables in the SYS scheama, we are given an error {noformat} TestVDB=> select * from sys.keys; ERROR: Group specified is ambiguous, resubmit the query by fully qualifying the group name: pg_attribute DETAIL: org.teiid.jdbc.TeiidSQLException: Group specified is ambiguous, resubmit the query by fully qualifying the group name: pg_attribute TestVDB=> select * from sys.columns; ERROR: Group specified is ambiguous, resubmit the query by fully qualifying the group name: pg_attribute DETAIL: org.teiid.jdbc.TeiidSQLException: Group specified is ambiguous, resubmit the query by fully qualifying the group name: pg_attribute TestVDB=> select * from sys.tables; ERROR: Group specified is ambiguous, resubmit the query by fully qualifying the group name: pg_attribute DETAIL: org.teiid.jdbc.TeiidSQLException: Group specified is ambiguous, resubmit the query by fully qualifying the group name: pg_attribute TestVDB=> {noformat} It looks like the teiid parser is getting confused somehow with multiple pg_attribute fields on those tables or something.
