Which JDBC features are and which features are not supported by jTDS?
jTDS offers full support for all JDBC 3.0 features: forward-only and scrollable/updateable result sets, batch updates, prepared and callable statements, unlimited number of statements per connection, complete database and result set meta data, and a DataSource implementation (which also implements ConnectionPoolDataSource and XADataSource). Features such as generated keys retrieval, named stored procedure parameters, and save points are also implemented. The only major features missing from jTDS are connection pooling and row sets; the reason for leaving these out is that there are free implementations available, probably much better than anything we could come up with.
