[jira] [Created] (PHOENIX-2559) sql query bug when primary key
involved to use skipScanFilter
ChenFangRong created PHOENIX-2559:
-------------------------------------
Summary: sql query bug when primary key involved to use skipScanFilter
Key: PHOENIX-2559
URL: https://issues.apache.org/jira/browse/PHOENIX-2559
Project: Phoenix
Issue Type: Bug
Affects Versions: 4.3.1, 3.3.1
Environment: centOS
Reporter: ChenFangRong
query results is incorrect when pk involved using '=' .
f
or example,
crate a table use sql:
create table bugTable(ID varchar primary key,company varchar);
upsert values use sql:
upsert into bugTable values('i1','c1');
upsert into bugTable values('i2','c2');
upsert into bugTable values('i3','c3');
the table is now like below,
+------------+------------+
| ID | COMPANY |
+------------+------------+
| i1 | c1 |
| i2 | c2 |
| i3 | c3 |
+------------+------------+
then use sql to query result from bugTable,
select * from bugTable where ID = 'i1' or (ID = 'i2' and company = 'c3');
the result expected:
+------------+------------+
| ID | COMPANY |
+------------+------------+
| i1 | c1 |
+------------+------------+
but, phoenix return the wrong result like below,
+------------+------------+
| ID | COMPANY |
+------------+------------+
| i1 | c1 |
| i2 | c2 |
+------------+------------+
the condition company = 'c3' is not used at all !
and then you can find when sql query combine primary key '=' somthing with any condition,then the condition is not used at all either, it means when the sql like this,
select xxx from xxx where pk = 'xxx' or (pk = 'xx' and any other condition);
the any other condition does not used at all.
I test the sql below all versions in phoenix before(including) version 4.3.1 & 3.3.1, it turns out that all the version sql query result is wrong.
I read the source code, and thought maybe the problem because when compile the sql query, the pushKeyToExpression method lost the condition, and method evaluate in AndOrExpression is not work.
