As a sidenote, The Microsoft driver and probably the others, too “optimize” this behavior by skipping over the update count, which is wrong according to the JDBC spec. We will make the necessary changes. If that’s the case, replace jtds. This is caused by triggers; replication is also implemented through triggers, so you will encounter this issue on replicated databases too. Please note that this flag only alters the behavior of executeUpdate ; execute will still return all update counts. As a general principle we try and keep synchronization to a minimum both for performance and deadlock reasons.

Unable to load database driver – help with datasource profile
You are required to use TDS 5. Features such as generated keys retrieval, named stored procedure parameters, and save points are also implemented.
Scenario iwhile it does work, is not necessarily a good solution because it requires a lot of locking and waiting on the same network connection plus last but not least a lot of caching.
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 jtfs URL’s syntax: For the moment you can get technical support from individual developers of jTDS. Or even better, a benchmark I can run myself?

There may be a number of reasons why this could happen:. What do i have to do to connect to Netcool Omnibus or any derived Product. It is possible to use mixed parameter lists to call stored procedures that do not have jtes parameters. As the server itself does not return an SQL state code, the SQLMessage class associates native error numbers with SQL state codes actually there’s a very comprehensive map there ; SQL Server originated errors and warnings that are not found in this map are given a default code of ‘S’, respectively ”.

This is common if say you are querying a stored procedure that creates a temp table, runs updates against it and then returns the table as a result set.
Why do I get a java. For example, if you jtdds 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.
If you can’t figure out why, ask your network administrator for help. The solution is to ntds the “TDS” property to “4. When calling a jts procedure that has output parameters, the driver has to call the procedure using a remote procedure call RPC.
Batch processing using executeBatch hangs or is unreliable on Sybase. 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. When jTDS sends the 8. The JNetDirect license precludes publication of performance test results.
Although queries returning multiple results are not very common, it is the reason why this behavior is customizable from the URL. 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.
Driver” or you mistyped the URL e. In this case the driver will be jtrs to use an RPC succesfully as all the parameters are represented by parameter markers?

Memory Usage Memory usage keeps increasing when using generated PreparedStatements. CallableStatement output parameter getter throws java. Until telnet doesn’t connect, jTDS won’t either. Is there any commercial technical support available for jTDS? This is what happens with SQL Server-returned errors and warnings and is consistent with how other drivers handle exceptions.
