> 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
> Assignee: Kevin Liew
> Labels: newbie
> Fix For: 4.9.0, 4.8.1
>
>
> 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 cell in col2 whereas it should only match single-character
> cells.
> This affects both VARCHAR and CHAR.
> Note that selecting by pattern '__' (two single-character wildcards) works
> properly for VARCHAR but not for CHAR (no result).
