Randy Gelhausen commented on PHOENIX-2757:
------------------------------------------
A customer ran into this issue trying to get the Phoenix driver to convert from
strings to datetimes.
Since HBase, Hive, Spark and other ecosystem projects handle type conversions
implicitly, or will accept arbitrary bytes, users would greatly appreciate the
JDBC driver managing conversions for them.
If the JDBC spec makes this difficult, perhaps there could be a driver
configuration that enables/disables such a feature.

> It appears that Phoenix currently does not know how to coerce a String into a
> Boolean (see
> [here|https://github.com/apache/phoenix/blob/master/phoenix-core/src/main/java/org/apache/phoenix/schema/types/PBoolean.java#L124-L137]).
> This is a feature that's present in other drivers such as PostgreSQL.
