Julien Aymé commented on DBUTILS-69:
------------------------------------
I think that in order to do what you want, you will need to implement a new
StringColumnListHandler class, which will call rs.getString method instead of
rs.getObject.
You just have to copy the ColumnListHandler code, and change it as you want.
This way, no cast would be required, and the list will contain only String
(since ResultSet#getString method is used).
It is safer to leave the current implementation as is, since there is no way to
know for sure the type returned by the getObject method.
