Subject [jira] [Created] (PHOENIX-2559) sql query bug when primary key involved to use skipScanFilter
Date Mon, 04 Jan 2016 02:49:39 GMT
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.
