[teiid-issues] [JBoss JIRA] (TEIID-4107) HSQL Syntax error when Teiid sends it a join query with no parenthesis

HSQL Syntax error when Teiid sends it a join query with no parenthesis ---------------------------------------------------------------------- Key: TEIID-4107 URL: https://issues.jboss.org/browse/TEIID-4107 Project: Teiid Issue Type: Bug Components: JDBC Connector Affects Versions: 7.0 Reporter: Gabriel Steinberg Assignee: Steven Hawkins Fix For: 9.0, 8.12.5, 8.13.4 The query SELECT R_NAME FROM region LEFT OUTER JOIN (customer INNER JOIN nation ON C_NATIONKEY = N_NATIONKEY) ON R_REGIONKEY = N_REGIONKEY When run against an HSQL DB causes a syntax error because the query passed to HSQL contains no parenthesis, and HSQL cannot handle it, as described in https://developer.jboss.org/message/953580?et=watches.email.thread#953580. As Steve points out there, this was solved for H2 in https://issues.jboss.org/browse/TEIID-3549. H2 and HSQL come from the same project, they split at some point in time, and I suspect they still share a lot of code.
