MSSQLServer4 - Accessing columns from a select with the same name

Question

The following describes a problem I'm encountering using the MSSQLServer4 driver...I have the following 2 tables (greatly simplified):
Create Table BOOK( BookId int, Name varchar(50), AuthorId int )
Create Table AUTHOR( AuthorId int, Name varchar(30) )
and my select is
Select BOOK.*, AUTHOR.*
From BOOK Inner Join AUTHOR On BOOK.AUTHORID = AUTHOR.AUTHORID
As you can see, the ResultSet from this select will have 2 identically named columns called "Name". I realize I could use an alias to differentiate the column names, but then I must list out every column in each table (quite ugly). I had EXPECTED to be able to do a resultSet.getString( "Author.Name" ), but that doesn't appear to work either. Next, I thought I could use the ResultSetMetaData.getTable()/ResultSetMetaData.getColumnName() to determine the ordinal value, but getTable() always returns "". Is there anyway to distinguish these two columns without using an alias?
Any help is greatly appreciated.
Regards...Marc

Regards...MarcHi. getTableName() will never work because the DBMS doesn't send the necessary metadata with the result
set that the driver would need to implement that call. If you get 'Name' for multiple column names, JDBC specifies
that getXXX("Name") will always return the first such named column. The only non-alias way is to know
the columns you're going to get in order, and just do getXXX(1), getXXX(2) etc.
