> Key: PHOENIX-3745

> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.9.0
> Reporter: chenglei
> Assignee: chenglei
> Fix For: 4.11.0
>
> Attachments: PHOENIX-3745_v2.patch

> Let us look a simple test case:
> h4. 1. Create two tables
> {noformat}
> CREATE TABLE IF NOT EXISTS MERGE1 (
> AID INTEGER PRIMARY KEY
> AGE INTEGER
> );
> CREATE TABLE IF NOT EXISTS MERGE2 (
> BID INTEGER PRIMARY KEY,
> CODE INTEGER
> );
> {noformat}
> h4. 2. Upsert values
> {noformat}
> UPSERT INTO MERGE1(AID,AGE) VALUES (1,11);
> UPSERT INTO MERGE1(AID,AGE) VALUES (2,22);
> UPSERT INTO MERGE1 (AID,AGE) VALUES (3,33);
> UPSERT INTO MERGE2 (BID,CODE) VALUES (1,66);
> UPSERT INTO MERGE2 (BID,CODE) VALUES (2,55);
> UPSERT INTO MERGE2 (BID,CODE) VALUES (3,44);
> {noformat}
> h4. 3. Execute query
> {noformat}
> select /*+ USE_SORT_MERGE_JOIN */ a.aid,b.code from
> (select aid,age from merge1 where age >=11 and age<=33) a inner join
> (select bid,code from merge2 order by code limit 1) b on a.aid=b.bid
> {noformat}
> h4. (/) Expected result
> {noformat}
> 3,44
> {noformat}
> h4. (!) Incorrect actual result
> {noformat}
> 1,66
> {noformat}
