James Taylor commented on PHOENIX-1102:
---------------------------------------
MultiCFCQKeyValueComparisonFilter is for cases in which multiple CF have the
same named CQ and thus for matching we must compare both the CF and the CQ.
MultiCQKeyValueComparisonFilter is for cases in which multiple CQ across one or
more CF are referenced, but the CQs are unique among them and thus only require
the CQ to be compared for matching.
> Query Finds No Rows When Using Multiple Column Families
> -------------------------------------------------------
>
> Key: PHOENIX-1102
> URL: https://issues.apache.org/jira/browse/PHOENIX-1102
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 3.0.0, 4.0.0, 5.0.0
> Reporter: James Taylor
> Assignee: Anoop Sam John
> Attachments: PHOENIX-1102.patch
>
>
> When using multiple column families, query does not find all expected rows.
>
> My table schema:
> CREATE TABLE IF NOT EXISTS FAMILY_TEST (
> NUM1 INTEGER NOT NULL,
> AA.NUM2 INTEGER,
> BB.NUM3 INTEGER,
> CONSTRAINT my_pk PRIMARY KEY (NUM1));
> I populated it with one row, assigning 1 to each field. I can verify that
> the record is there, but I can not get a simple expression working that uses
> fields across two column families:
> SELECT * FROM FAMILY_TEST;
> NUM1 NUM2 NUM3
> ---------- ---------- ----------
> 1 1 1
> Time: 0.038 sec(s)
> SELECT * FROM FAMILY_TEST WHERE NUM2=1 AND NUM3=1;
> no rows selected
> Time: 0.039 sec(s)
> I understand that columns to be queried together should usually be in the
> same column family for efficiency, but I did not expect my second query to
> not work at all. Or if it is not supported, I would expect an error. I get
> the same results if I use AA.NUM2 and BB.NUM3 as well.
> I am using Phoenix 3.0.0.
