Ankit Singhal created PHOENIX-5884:
--------------------------------------
Summary: Join query return empty result when filters for both the
tables are present
Key: PHOENIX-5884
URL: https://issues.apache.org/jira/browse/PHOENIX-5884
Project: Phoenix
Issue Type: Bug
Reporter: Ankit Singhal
Assignee: Ankit Singhal
Let's assume DDL to be same for both the tables involved in a join
{code}
CREATE TABLE LeftTable ( id1 CHAR(6) NOT NULL, id2 VARCHAR(22) NOT NULL,
id3 VARCHAR(12) NOT NULL, id4 CHAR(2) NOT NULL, id5 CHAR(6) NOT NULL,
id6 VARCHAR(200) NOT NULL, id7 VARCHAR(50) NOT NULL, ts TIMESTAMP ,
CONSTRAINT PK_JOIN_AND_INTERSECTION_TABLE PRIMARY
KEY(id1,id2,id3,id4,id5,id6,id7))
{code}
Following query return right results
{code}
SELECT m.*,r.* FROM LEFT_TABLE m join RIGHT_TABLE r on m.id3 = r.id3 and m.id2
= r.id2 and m.id4 = r.id4 and m.id5 = r.id5 and m.id1 = r.id1 and m.ts =
r.ts where r.id1 IN ('201904','201905') and r.id2 = 'ID2_VAL' and r.id3 IN
('ID3_VAL','ID3_VAL2')
{code
but When to optimize the query, filters for the left table are also added ,
query returned empty result . Though the filters are based on join condition so
semantically above query and below query should be same.
{code}
SELECT m.*,r.* FROM LEFT_TABLE m join RIGHT_TABLE r on m.id3 = r.id3 and
m.id2 = r.id2 and m.id4 = r.id4 and m.id5 = r.id5 and m.id1 = r.id1 and m.ts
= r.ts where m.id1 IN ('201904','201905') and r.id1 IN ('201904','201905')
and r.id2 = 'ID2_VAL' and m.id3 IN ('ID3_VAL','ID3_VAL2') and
r.id3 IN ('ID3_VAL','ID3_VAL2')
{code}
