NPE in simple select with procedure subquery -------------------------------------------- Key: TEIID-5922 URL: https://issues.redhat.com/browse/TEIID-5922 Project: Teiid Issue Type: Bug Components: Query Engine Reporter: Steven Hawkins Assignee: Steven Hawkins Priority: Major Fix For: 14.0, 13.1.1 Original Estimate: 4 hours Time Spent: 1 hour, 30 minutes Remaining Estimate: 2 hours, 30 minutes A query in the form of: SELECT (call proc()) is resulting in an npe: {code} java.lang.NullPointerException at org.teiid.query.optimizer.relational.rules.RulePlanSubqueries.planMergeJoin(RulePlanSubqueries.java:272) at org.teiid.query.optimizer.relational.rules.RulePlanSubqueries.processSubqueries(RulePlanSubqueries.java:232) at org.teiid.query.optimizer.relational.rules.RulePlanSubqueries.execute(RulePlanSubqueries.java:193) at org.teiid.query.optimizer.relational.RelationalPlanner.executeRules(RelationalPlanner.java:1101) {code} Until relatively recently we disallowed queries from having subqueries if there was no from clause. That change was checked against regular subqueries, but apparently not procedure subqueries.
