Hi Joe,

Thank you for taking time to help review.

Wanted a test which made sure that for the number of columns in the metadata that the fields can be set.  Does it have to, not really, but it wanted to sanity check that they could
> There doesn't seem to be a differentiator or different factor between the columns, e.g if one column is set to auto_increment and another not, the results would be different. Also in the test, some of the setters seem to be invalid, for example, whether the column is auto_increment or not shall affect setters such as setPrecision, setScale, setNullable, isReadOnly, isWritable and etc., shouldn't it?

For this abstract class it is just a matter of validating the methods can be set for the various columns.

in an implementation of a RowSet, the data associated with a given column will have more actual meaning based on the column definition.  So yes the values being set  are  somewhat artificial but that is OK in this instance.

Also different databases for example can allow an auto-incrementable column to be writable, others do not so your milage varies as to which fields can and cannot have coresponding values.

Best,
Lance
