Memory Usage Memory usage keeps increasing when using generated PreparedStatements. This is what happens with SQL Server-returned errors and warnings and is consistent with how other drivers handle exceptions. As a conclusion the only safe multithreading scenarios are these:

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. Properties can be passed to jTDS in one of three ways: In this case the driver will be able to use an RPC succesfully as all the parameters are represented by parameter markers? It is also recommended that you execute each batch in a transaction i.
How to proceed In the Bamboo server home directory, bamboo. The set of properties supported by jTDS is:. Jtcs trying to connect to SQL Server jtdd. In this case the driver will substitute the parameters locally and use a jfds “execute procedure” SQL call; however, this mode of execution is less efficient than an RPC.
Microsoft’s driver is actively maintained, where jTDS hasn’t been updated since and prior to the small round of updates done in it hadn’t been updated for multiple years.
Incorrect Behavior CallableStatement output parameter getter throws java. Now you can use GORM to query the database. What do I have to do? As I understand it the purpose of the keys is much like foreign keys in our world, used to tie various objects together. Can jTDS be used in a multi threaded application? But if the stored procedure returns at least one ResultSet jTDS will only cache the update counts up to the first ResultSet and you will have to call getMoreResults to process all the results.
It is possible to use mixed parameter lists to call stored procedures that do not have output parameters. CallableStatement output parameter getter throws java. 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. The existing configuration should look similar to this:. If that’s the case, replace jtds. The resulting queries against the views were trivial, and the occasional update seemed fine as well.
SSO in the distribution package for information on how to install it. The exception you are getting is usually caused by a timeout. Please register or log in to leave graila comment.

This is what happens with SQL Server-returned errors and warnings and is consistent graiks how other drivers handle exceptions. 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. You will have to use the instance property either append it to the URL or place it into the Properties you supply to getConnection instead of doing it the Microsoft way. Or even better, a benchmark I can run myself?
Memory Usage Memory usage keeps increasing when using generated PreparedStatements. So, for maximum compatibility, it is recommended that you use execute anytime you run queries returning more than one result even if the particular driver you are using allows you to do otherwise.
jtxs Daily SQL Articles by email:. 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.
There are three possible causes to this if we exclude not creating the ResultSet with the appropriate type and concurrency in the first place:.
You can control the real batch size using the batchSize parameter; setting it to a non-zero value will break up batches into smaller pieces on execution, hopefully avoiding the problem.
