----------------------------------
Attachment: PHOENIX-3328.patch
> Skip scan optimization failed for multi pk columns
> --------------------------------------------------
>
> Key: PHOENIX-3328
> URL: https://issues.apache.org/jira/browse/PHOENIX-3328
> Project: Phoenix
> Issue Type: Bug

> {code:sql}
> create table t1 (pk integer primary key, a integer);
> create table t2 (pk1 integer not null, pk2 integer not null, a integer
> constraint pk primary key (pk1, pk2));
> explain select * from t1 where (pk > 10 and pk < 20) or (pk > 30 and pk < 40);
> explain select * from t2 where (pk1 > 10 and pk1 < 20) or (pk1 > 30 and pk1 <
> 40);
> {code}
> The first SELECT statement will use skip scan filter for two ranges, so as
> the second one. But actually the WhereOptimizer failed doing so and using a
> full table scan instead. This happens for tables have multi PK columns.
