>          Components: SQL

> Using oracle 11g as a datasource with ojdbc7.jar. When importing data into a scala app, I am getting an exception "Overflowed precision". Some times I would get the exception "Unscaled value too large for precision".
> This issue likely affects older versions as well, but this was the version I verified it on.
> I narrowed it down to the fact that the schema detection system was trying to set the precision to 0, and the scale to -127.
> I have a proposed pull request to follow.
