Would that work?
This could work if you could tell SQL Sever through a connection parameter passed to SQLServerDriver or some property set on SQLServerConnection, but I didn't see a method that would do that.

Would that work? This might be possible if we executed the SET IDENTITY_INSERT once per connection. When I tried this, however, it didn't seem to persist between PreparedStatements. I also tried doing a PreparedStatement.addBatch("SET IDENTITY_INSERT...") before the executeBatch() is called. This resulted in "com.microsoft.sqlserver.jdbc.SQLServerException: The method addBatch() cannot take arguments on a PreparedStatement or CallableStatement." Do you have an idea about how this could be done specifically? - Keegan ----------------------------------------------------------- This is an automatically generated e-mail.
