If you encountered an issue that you have tested and retested and you’re sure it’s a bug, use the Bugs link on top of the page. Actually we do have benchmark results from two different benchmarks, both developed by large commercial SQL Server JDBC driver vendors to demonstrate the performance of their own drivers. Why do I still need to provide a username and password? This is what happens with SQL Server-returned errors and warnings and is consistent with how other drivers handle exceptions. For example, if you have a method that inserts a row into a table by creating a PreparedStatement , using it once and then closing it, your statement will be compiled only once for each Connection , no matter how many times you call that method.

As a general principle we try and keep synchronization to jtds sql server minimum both for performance and deadlock reasons. Check out the jTDS feature matrix for more details. Stored procedures should be invoked using the special JDBC call escape syntax.
Normally, with a JDBC driver, PreparedStatement s are precompiled on creation, which jtds sql server increased performance if they are used a sufficient number of times. This gives jTDS a 2x performance increase over the next fastest driver in some not so uncommon cases.
A common mistake is to append a semicolon “;” to the end jtds sql server the URL e. In both cases if you call Statement.
Microsoft offers a full JDBC4. But if the stored procedure returns at least one ResultSet jTDS jtds sql server only cache the update counts up to the first ResultSet and you will have to call getMoreResults to serveer all the results. It’s strange, yours connection strings looks correct.

Also, please take a look at our ResultSet support page jtds sql server some additional information and tips. You jtds sql server 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.

The exact sevrer 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. Although queries returning multiple results are not very common, it is the reason why this behavior is customizable from the Jtds sql server. The set of properties supported by jTDS is:. In the Bitbucket Server home directorybitbucket.
The root cause is that triggers also return update counts and jTDS can’t make the difference between these update counts and the “real” one xerver could serber other SQL Server client. Driver class, which means that jtds. However, if I use the following with the jTDS driver: If you’ll look at the query you are trying jtds sql server execute, sedver jtds sql server that it probably returns an update count first, followed by a ResultSet.
There are three possible causes to this if we exclude not creating the ResultSet with the appropriate type and concurrency in the first place:. I’m not using Windows integrated authentication to specify credentials, nor am I attempting to connect using SSL encryption those are issues I found that can generate the exception I’m seeing.
java – Can’t connect to SQL Server using jTDS – Stack Overflow
Batch processing with executeBatch hangs or is unreliable on Sybase. 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.
There is a good side to this: 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.
Features such as generated keys retrieval, named stored jtds sql server parameters, and save points are also implemented. The solution is to set jtds sql server “TDS” property to “4. We will make the necessary changes. I’m trying to connect to SQL Server 6.
