Limit is not added with multiple nulls in select on outer query to an inline view --------------------------------------------------------------------------------- Key: TEIID-3129 URL: https://issues.jboss.org/browse/TEIID-3129 Project: Teiid Issue Type: Enhancement Components: Query Engine Affects Versions: 8.9 Reporter: Sanjeev Gour Assignee: Steven Hawkins Fix For: 8.9 When a query does multiple null selects in the in the outer query to an inline view and you only have a DISTINCT constant selected from the view definition, a limit 1 is expected to be applied to the inline view query which does not happen. Here is the sample query- SELECT DISTINCT c1, null as c2, null as c3 FROM( SELECT c1, c2 FROM ( SELECT 'const_col_1' as c1, ID as c2 FROM FIRST_SCHEMA.FIRST_TABLE UNION ALL SELECT 'const_col_2' as c1, ID as c2 FROM SECOND_SCHEMA.SECOND_TABLE ) as v ) as v1 The query will contain queries to the inline view without a limit like the following- SELECT 'const_col_1' FROM h2extended.TEST.FIRST_SCHEMA.FIRST_TABLE AS g_0 -------------------LIMIT 1 is not applied here Full query plan and the detail are capture in this discussion- https://developer.jboss.org/thread/248787
