Improve error message when using LATERAL reference in RIGHT or FULL joins ------------------------------------------------------------------------- Key: TEIID-5272 URL: https://issues.jboss.org/browse/TEIID-5272 Project: Teiid Issue Type: Quality Risk Components: Query Engine Affects Versions: 10.1 Environment: teiid-10.1.0 on WildFly Full 11.0.0.Final (WildFly Core 3.0.8.Final) Reporter: dalex dalex Assignee: Steven Hawkins Fix For: 10.2 All table functions cause errors in queries containing RIGHT or FULL JOINs. For example, such query: {code:sql} select * from views.v x1 right join table(select x1.b a) x2 on x1.a=x2.a ;; {code} causes such error: {code:noformat} 2018-03-05 10:25:02,356 WARN [org.teiid.PROCESSOR] (Worker3_QueryProcessorQueue31) /oCxMs2/Zs22 TEIID30020 Processing exception for request /oCxMs2/Zs22.26 'TEIID31119 Symbol x1.b i s specified with an unknown group context'.

Lateral is expected to work left to right - thus only with inner/left joins. The error message should be improved. On pgsql it is "The combining JOIN type must be INNER or LEFT for a LATERAL reference".
