-------------------------------------

             Summary: 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
            Reporter: William Yang
            Priority: Minor


{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.
