Incorrect rewrite of subquery ----------------------------- Key: TEIID-1617 URL: https://issues.jboss.org/browse/TEIID-1617 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 7.4 Reporter: Steven Hawkins Assignee: Steven Hawkins Priority: Critical Fix For: 7.4.1 when performing a semi-join against a query with a key preserved in the semi join criteria and a non-distinct subquery the planner will incorrectly created an unnested query that does not preserve the semi-join. This can happen with either the explicit mj hint or with the query unnesting property set. e.g. select col2 from tbl where keyCol IN (select dupCol from tbl2) will become select col2 from tbl, tbl2 where keyCol = tbl2 rather than select col2 from tbl, (select distinct dupCol from tbl2) x where keyCol = tbl2 -- This message is automatically generated by JIRA.
