Until telnet doesn’t connect, jTDS won’t either. In this case it’s the net. The number of statements that are kept open simultaneously can be controlled with the maxStatements parameter; see the jTDS URL format for more information. 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 jtdw that are not found in this map are given a default code of ‘S’, respectively ”.
Why do I get a java. Sign up or log in Sign up using Google. Features such as generated keys retrieval, named stored procedure parameters, and save points are also implemented. 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.
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: You can control the real batch size using the batchSize parameter; setting jds to a non-zero value will break up batches into smaller pieces on execution, hopefully avoiding the problem. Jds are three possible causes to this if we exclude not creating the ResultSet with the appropriate type and concurrency in the first place:.
We will make the necessary changes. This means among other things that it cannot access platform-specific features, jtdss as determining the currently logged user and his credentials.
When jTDS sends the 8. Is there any commercial technical support available for jTDS? 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: For queries that return multiple results the JDBC spec requires execute to be used.
What do i have to do to connect to Netcool Omnibus or any derived Product.
Of course, we will keep offering support on our SourceForge forums just as we did until now. If you are getting this in an application, start your application with. 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.
Or even better, a benchmark I can run myself? Actually we do have benchmark mhsql from two different benchmarks, both developed by large commercial SQL Server JDBC driver vendors to demonstrate the performance of their own drivers.
The “No suitable driver” exception is thrown by the DriverManager when none of the registered Driver implementations recognizes the supplied URL.
JDBC Driver Libraries for different types of database in Java
The default install does not configure the SQL Browser service to start automatically so you must do it manually. The “Connection refused” exception is thrown by jTDS when it is unable to connect to the server. Batch processing with executeBatch hangs or is unreliable on Sybase.
Why do column names more than 30 characters long, get chopped jds at 30 characters? Have you got any figures to prove that? Post as a guest Name. So for procedures returning ResultSet s you will have to loop, consuming all results before reading the output parameters i.
In this case the driver will substitute the parameters locally and use a normal “execute procedure” SQL call; however, this mode of execution is less efficient than an RPC. Web Design Anca Sinpalean.
How to Connect MS SQL Server using JTDS Driver
In these circumstances the driver raises an exception and execution fails. SQL is sent to the server each time without any preparation, literals are inserted in the SQL slower.
These benchmarks are free to download so we encourage you to do it and run them yourself.
