Stored procedures should be invoked using the special JDBC call escape syntax. 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 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. You are very probably using TDS 4. This gives jTDS a 2x performance increase over the next fastest driver in some not so uncommon cases.

Unable to load database driver – help with datasource profile
As a general principle we try and keep synchronization to a minimum both for performance jds deadlock reasons. Driver class, which means that jtds. 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 ”.
The solution is to set the “TDS” property to “4. 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.
If you experience this problem with versions 0. There may be a number of reasons why this could happen:.
This gives jTDS a 2x performance increase over the next fastest driver in some not so uncommon cases. 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.
Features such as generated keys retrieval, named stored procedure parameters, and save points are also implemented. 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: 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.
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.
If you can’t figure out why, ask your network administrator for help. Have you got any figures to prove that? In order to change that you have poad specify it explicitly in the Properties or the URL you supply when you create the connection.
You are very probably using TDS 4. There is a good side to this: The set of properties supported by jTDS is:. In this case the driver will be able to use an RPC succesfully as all the parameters are represented by parameter markers? What should I do?
Memory usage keeps increasing when using generated PreparedStatements. When executing large batches on Sybase the client application may hang or the response time may vary considerably. Without the native SSO library installed you still have to provide the username and password because otherwise loac cannot determine user credentials. The JNetDirect license precludes publication of performance test results.
When jTDS sends the 8. The default install does not configure the SQL Browser service to start automatically so you must do it manually. Until telnet doesn’t connect, jTDS won’t either.
Please note that this flag only alters the behavior of executeUpdate ; execute will still return all update counts. We will make the necessary changes.
[SQL] Unable to load database driver – help with datasource profile – JIRA
Indeed, some SQLExceptions are reported with a correct state code and some not. A common solution rather than the inelegant loda and then cycling through multiple result sets, is to supress the jtxs counts for statements you are uninterested in. Temporary stored procedures are created for each unique SQL statement and parameter combination faster. 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.
