[teiid-issues] [JBoss JIRA] Resolved: (TEIID-949) Criteria on constant column with aggregate function doesn't push criteria down correctly

Criteria on constant column with aggregate function doesn't push criteria down correctly ---------------------------------------------------------------------------------------- Key: TEIID-949 URL: https://jira.jboss.org/jira/browse/TEIID-949 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 6.0.0 Environment: MM5.5.4 Reporter: Larry O'Leary Assignee: Steven Hawkins Fix For: 7.0 When a column value is a constant and used along with an aggregate, criteria on the constant column is being ignored. Here is an example query: SELECT * FROM ( SELECT b.count, enterprise_id FROM ( SELECT COUNT(*), 35 AS enterprise_id FROM ( SELECT "A Name" AS Name, 37 AS enterprise_id ) c ) b ) a WHERE enterprise_id = 1 OPTION DEBUG The expected result is an empty result set. Instead, the result set comes back as: COUNT, ENTERPRISE_ID 0, 35 The resulting plan looks like: OPTIMIZATION COMPLETE: PLAN TREE: (type=Relational, command=SELECT * FROM (SELECT b."count", enterprise_id FROM (SELECT COUNT(*), 35 AS enterprise_id FROM (SELECT 'A Name' AS Name, 37 AS enterprise_id) AS c) AS b) AS a WHERE enterprise_id = 1 OPTION DEBUG, props={0=PlanHints}) canonical plan: Project(groups=[b], props={90=[b."count", enterprise_id], 30=[b."count", enterprise_id], 114=0.0, 91=[A."COUNT", A.ENTERPRISE_ID]}) Source(groups=[b], props={90=[b."count", enterprise_id], 64=SELECT COUNT(*), 35 AS enterprise_id FROM (SELECT 'A Name' AS Name, 37 AS enterprise_id) AS c, 114=0.0, 60={b."count"=COUNT(*), b.enterprise_id=35}}) Project(groups=[], props={90=[b."count", enterprise_id], 30=[COUNT(*), 35 AS enterprise_id], 114=0.0, 60={b."count"=COUNT(*), b.enterprise_id=35}, 91=[COUNT(*), 35 AS enterprise_id]}) Group(groups=[c], props={90=[COUNT(*)], 114=0.0, 81=[COUNT(*)]}) Null(groups=[c], props={90=[], 114=0.0}) PROCESSOR PLAN: ProjectNode(1) output=[b."count", enterprise_id] [b."count", enterprise_id] ProjectNode(2) output=[b."count", enterprise_id] [COUNT(*), 35 AS enterprise_id] GroupingNode(3) output=[COUNT(*)] null NullNode(4) output=[] If the query is changed as follows, the expected result is received: SELECT * FROM ( SELECT b.count, enterprise_id FROM ( SELECT COUNT(*), 35 AS enterprise_id FROM ( SELECT "A Name" AS Name, 37 AS enterprise_id ) c GROUP BY enterprise_id ) b ) a WHERE enterprise_id = 1 OPTION DEBUG Which yields a very similar plan: PLAN TREE: (type=Relational, command=SELECT * FROM (SELECT b."count", enterprise_id FROM (SELECT COUNT(*), 35 AS enterprise_id FROM (SELECT 'A Name' AS Name, 37 AS enterprise_id) AS c GROUP BY enterprise_id) AS b) AS a WHERE enterprise_id = 1 OPTION DEBUG, props={0=PlanHints}) canonical plan: Project(groups=[b], props={90=[b."count", enterprise_id], 30=[b."count", enterprise_id], 114=0.0, 91=[A."COUNT", A.ENTERPRISE_ID]}) Source(groups=[b], props={90=[b."count", enterprise_id], 64=SELECT COUNT(*), 35 AS enterprise_id FROM (SELECT 'A Name' AS Name, 37 AS enterprise_id) AS c GROUP BY enterprise_id, 114=0.0, 60={b."count"=COUNT(*), b.enterprise_id=35}}) Project(groups=[], props={90=[b."count", enterprise_id], 30=[COUNT(*), 35 AS enterprise_id], 114=0.0, 60={b."count"=COUNT(*), b.enterprise_id=35}, 91=[COUNT(*), 35 AS enterprise_id]}) Group(groups=[c], props={90=[COUNT(*)], 114=0.0, 80=[enterprise_id], 81=[COUNT(*)]}) Null(groups=[c], props={90=[enterprise_id], 114=0.0}) PROCESSOR PLAN: ProjectNode(1) output=[b."count", enterprise_id] [b."count", enterprise_id] ProjectNode(2) output=[b."count", enterprise_id] [COUNT(*), 35 AS enterprise_id] GroupingNode(3) output=[COUNT(*)] [enterprise_id] NullNode(4) output=[enterprise_id] Except the NullNode node contains enterprise_id as its target column vs an empty value.
