Indeed, some SQLExceptions are reported with a correct state code and some not. You need to put. Please note that this flag only alters the behavior of executeUpdate ; execute will still return all update counts. 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: The classpath for a Java application is a list of directories and jar files that the classloader will use to find the classes you’re using.

In the FAQ is written: The exact values to use in the new URL are beyond the scope of this documentation; they must be chosen based on the jTDS settings they are replacing.
The JNetDirect license precludes publication of performance test results. Related content No related content found. For the moment you can get technical support from individual developers of 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: 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. You are required to use TDS 5.
If you are using Eclipse: In this case the driver will be able to use an RPC succesfully as all the parameters are represented by parameter markers? 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. Jtdds number of statements that are kept open simultaneously can be controlled with the maxStatements parameter; see the jTDS URL format for more information.
A jtdd mistake is to append a semicolon “;” to the end of the URL e. Driver class, which means that jtds.
A common solution rather than the inelegant execute and then cycling through multiple result sets, is to supress the update counts for statements you are uninterested in. Second place is your classpath, where you load. It is also recommended that you execute each batch in a transaction i.
Transitioning from jTDS to Microsoft’s JDBC driver – Atlassian Documentation
Although queries returning multiple results are not very common, it is the reason why this behavior is customizable from the URL. This parameter is lastUpdateCount and you can find out more about it here. 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.
Memory usage keeps increasing when using generated PreparedStatements. 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.
Indeed, some SQLExceptions are reported with a correct state code and some not.
2a. Installing the JDBC Driver
As a conclusion the only safe multithreading scenarios are these: Microsoft offers a full JDBC4. Please note that this flag only alters the behavior of executeUpdate ; execute will still return all update counts. Stored procedures should be invoked using the special JDBC call escape syntax.
The only part of jTDS we guarantee is thread safe is the Connection object, and multi threaded access to Statement s is discouraged except for issuing cancels.
If you are using command line: When jTDS sends the 8. The solution innstall to set the “TDS” property to “4.

When executing large batches on Sybase the client application may hang or the response time may vary considerably. 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 ”. In both cases if you call Statement. The name of the jTDS jar file may be jtds Of course, we will keep offering support on our SourceForge forums just as we did until now.
