Column mappings failed

[LinggaAskaEdo]

Based on this docs: https://github.com/aaberg/sql2o/wiki/Column-mappings

1. Failed mapping when SELECT

Old query: SELECT created_date createdDate, user_id userId, phone FROM mob_user WHERE userId = :userIdParam
Exception: Database error: ORA-00904: "USERID": invalid identifier

But its success when query like this:
New query: SELECT created_date createdDate, user_id userId, phone FROM mob_user WHERE user_id = :userIdParam

2. Failed mapping when UPDATE

Old query: UPDATE mob_user SET cuid = :cuidParam WHERE user_id = :userIdParam
Exception: - (but field not updated)

But its success when query like this:
New query: UPDATE mob_user SET cuid = :cuidParam WHERE phone = :phoneParam

Can you help me what's wrong??? I see something is wrong with the column using underscore. I'm using sql2o version 1.6.

@LinggaAskaEdo could you extend your context , how your table looks like, how do you execute queries above, what database do you use
