What underlying data type are you trying to call these methods on?  You
need to provide some more information to describe what you are doing.

What JDBC driver version are you using?

What is the type of the columns that you are calling getPrecision() and
getScale() on? Do you have an example schema and query I can try out?

What are the results you get? What are the results you expected to get?

I don't believe getPrecision is intended to operate on non-numeric fields.
Perhaps you are looking for getColumnDisplaySize() ?
