[teiid-issues] [JBoss JIRA] (TEIID-3525) dependent join handling of multi-way joins

dependent join handling of multi-way joins ------------------------------------------ Key: TEIID-3525 URL: https://issues.jboss.org/browse/TEIID-3525 Project: Teiid Issue Type: Quality Risk Components: Query Engine Reporter: Steven Hawkins Assignee: Steven Hawkins Fix For: 8.12 In scenarios where the same column is used multiple times in a multi-way dependent join, it's affect may be duplicated in source predicates. For example: select pm1.g1.e1, pm1.g1.e2, pm2.g1.e2 FROM pm1.g2, pm1.g1, /*+ makedep */ pm2.g1 where pm1.g1.e1 = pm2.g1.e1 and pm1.g2.e1 = pm2.g1.e1 Should have a source query of the form: SELECT g_0.e1 AS c_0, g_0.e2 AS c_1 FROM pm2.g1 AS g_0 WHERE g_0.e1 IN (<dependent values>) ORDER BY c_0 Rather than having multiple dependent values predicates.
