In this case the driver will be able to use an RPC succesfully as all the parameters are represented by parameter markers?
When executing large batches on Sybase the client application may hang or the response time may vary considerably. For example, if you have a method that inserts a row into a table by creating a PreparedStatementusing it once and then closing it, your statement will be compiled only once for each Connectionno matter how many times you call that method.
Although queries returning multiple results jtss not very common, it is the reason why this behavior is customizable from the URL. The JNetDirect license precludes publication of performance test results.
When calling a stored procedure that has output parameters, the driver has to call the procedure using a remote procedure call RPC.
I have used Class. CallableStatement output parameter getter throws java. Is there any commercial technical support available for jTDS? In both cases if you call Statement. When executing a stored procedure or any query, for that matter the response from the SQL Server is serialized in the same order it is executed in: You are required to use TDS 5.
If you experience this problem with versions 0. There is a good side to this: Batch processing with executeBatch hangs or is unreliable on Sybase.
This gives jTDS a 2x performance increase over the next fastest driver in some not so uncommon cases. Because there is no URL when using the JtdsDataSource there are three other properties with setters and getters to take the place of those items that are part of the URL’s syntax: Memory Usage Memory usage keeps increasing when using generated PreparedStatements.
JDBC Driver Libraries for different types of database in Java
Why do I still need to provide a username and password? This is caused by triggers; replication is also implemented through triggers, so you will encounter this issue on replicated databases too. This parameter is lastUpdateCount and you can find out more about it here. Sign up jhds Email and Password.

Jtda case you are wondering if this is right, this is a quote from the CallableStatement API documentation: If you’ll look at the query you are trying to execute, you’ll see that it probably returns an update count first, followed by a ResultSet. Although this means that a “good” driver could “fix” this behavior, fixing it would imply caching the whole server response, equaling a huge performance drop.
While doing this it times out, throwing the exception you see which means that jTDS was not able to get information about the running instances. Can jTDS be used in a multi threaded application? In our oppinion this is better than having a benchmark of our own, which could be designed in such a way as to give jTDS the edge.
