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
