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. Batch processing with executeBatch hangs or is unreliable on Sybase. There may be a number of reasons why this could happen:. Interface jTDS Implementation java. Without the native SSO library installed you still have to provide the username and password because otherwise jTDS cannot determine user credentials. If you need help with any other jTDS-related issue, search the Help forum first and if you still don’t find anything, post a question. In these circumstances the driver raises an exception and execution fails.

Because there is no URL when using the JtdsDataSource there are three other properties with setters and getters to take the place of com.internetcds.jdhc.tds.driver items that are part of the URL’s syntax: This is what happens with SQL Server-returned errors and warnings and is consistent with how other drivers handle exceptions.

Where does one place an instance name in the connect string? ClassNotFoundError is thrown by the classloader when it can not find a certain class.

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 ssl do otherwise. Hai, Now its working fine, Thank you for all your replies. As a conclusion, when executing stored procedures that only return update counts output parameters will be available immediately, as jTDS will process and cache the whole response.


Here are the results of the i-net test: In both cases if you call Statement. 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.

Microsoft JDBC Driver for SQL Server – SQL Server | Microsoft Docs

Class-Path May 16, 9: A common mistake is to append a semicolon “;” to the end of the URL e. In case you are wondering if this is right, this is a quote from com.internetcds.jdbc.tdsdriver CallableStatement API documentation: Of course, we will keep offering support on our SourceForge forums just as we did until now.

The root cause is that triggers also return update counts and jTDS can’t com.internetcds.jdbc.tds.drivrr the difference between these update counts and the “real” one neither could any other SQL Server client. This gives jTDS a 2x performance increase over the next fastest driver in some not so uncommon cases.

Incorrect Behavior CallableStatement output parameter getter throws java. Why do I get java. The exception is thrown because it’s better to warn the user that the output parameters are not yet set instead of leaving the impression that all is ok and cause other, harder to detect problems.

I m using SQL Server Memory Usage Memory usage keeps increasing when using generated PreparedStatements. As a conclusion the only safe multithreading scenarios are these: The default install does not configure the SQL Browser service to start automatically so you must do it manually.


Connecting iReport to a Microsoft SQL Datasource

If you are getting this in an application, start your application with. Without the native SSO library installed you still have to provide the username and password because otherwise jTDS cannot determine user credentials.

The below error was raised.

However, you can run any of the benchmarks yourself, the effort is minimal. Will meet you later.

As a general principle we try and keep synchronization to a minimum both for performance and deadlock reasons. If you can’t figure out why, ask your network administrator for help. Memory usage keeps increasing when using generated PreparedStatements.

In this case the driver will be able to use an RPC succesfully as all the parameters are represented by parameter markers? 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.

Please be thoughtful, detailed and courteous, and adhere to our posting rules. For the moment you can get technical support from individual developers of jTDS.
