public class JtdsDatabaseMetaData
extends java.lang.Object
implements java.sql.DatabaseMetaData
Implementation note:
This is basically the code from the original jTDS driver. Main changes relate to the need to support the new ResultSet implementation.
TODO: Many of the system limits need to be revised to more accurately reflect the target database constraints. In many cases limits are soft and determined by bytes per column for example. Probably more of these functions should be altered to return 0 but for now the original jTDS values are returned.

throws java.sql.SQLException
true if updates are made to a copy of the LOB; returns
false if LOB updates are made directly to the database.
NOTE: Since SQL Server / Sybase do not support LOB locators as Oracle does (AFAIK);
this method always returns true.
