Backward, confusing error message when you use the wrong ResultSet.getXXX() method in the client
driver
-------------------------------------------------------------------------------------------------------

                 Key: DERBY-4949
                 URL: https://issues.apache.org/jira/browse/DERBY-4949
             Project: Derby
          Issue Type: Bug
          Components: Network Client
    Affects Versions: 10.8.0.0
            Reporter: Rick Hillegas
         Attachments: zz.java

If you try to get a Time value out of an INTEGER column, the client driver gives this error.
I believe that similar nonsense comes back when you try other mismatched getters on other
datatypes:

    "An attempt was made to get a data value of type 'java.sql.Types 4' from a data value
of type 'java.sql.Time'."

The exception is a java.sql.SQLDataException with SQLState 22005. A better message would be:

    "An attempt was made to get a data value of type 'java.sql.Time' from a data value of
type INTEGER'."

I recommend two improvements to the utility method which generates these exceptions:

1) Flip the order of the type names.

2) Use the ResultSetMetaData to look up the source data type name.
