When I execute a bulk 'update' SQL statement on a table that contains more than 20 rows, it appears to only update the
first page of 'results'.  For example, if I have a table 'USER', which has a column 'ENABLED', and I want to disable all
of the users, I might execute the following query:

   update USER set ENABLED = 0

The intention here is to update every row in the table.  If I have 100 rows, however, I receive the following response:

Executed successfully in 0.094 s, 21 rows affected.
Line 1, column 1

At first, the table looks correct when I view the data, because I'm shown the first 20 entries, but if I go to page 2 of
the results, I start to see that the values are unchanged.

This is occurring on SQL Server 2005, with the Microsoft JDBC driver.
