    • HIVE-236. RLIKE/REGEXP allowing matching of partial strings. (Paul Yang via zshao)

    Description

      The current behavior is that the regexp needs to match the whole string.

      But from mysql: ( http://dev.mysql.com/doc/refman/5.0/en/regexp.html#operator_regexp )

      mysql> SELECT 'fofo' REGEXP '^fo'; -> 1

      We need to make it work the same way as MySQL.
