[jira] [Created] (PHOENIX-2641) Implicit wildcard in LIKE predicate search pattern

Kevin Liew created PHOENIX-2641:
-----------------------------------

             Summary: Implicit wildcard in LIKE predicate search pattern
                 Key: PHOENIX-2641
                 URL: https://issues.apache.org/jira/browse/PHOENIX-2641
             Project: Phoenix
          Issue Type: Bug
    Affects Versions: 4.7.0
         Environment: Phoenix 4.7.0 on Calcite 1.5.0
            Reporter: Kevin Liew


LIKE predicates have an implicit wildcard at the end of the search pattern

ie.
{code:sql}select distinct at1.col2 from at1 group by at1.col2 having at1.col2 like '_'{code}
will match every row in the table, including NULL cells
