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: As a sidenote, The Microsoft driver and probably the others, too “optimize” this behavior by skipping over the update count, which is wrong according com.internetcds.jbc.tds.driver the JDBC spec.

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. Memory Usage Memory usage keeps increasing when using generated PreparedStatements. Although queries returning multiple results are not very common, it is the reason why this behavior is customizable from the URL.

This is what happens with SQL Server-returned errors and warnings and is consistent with how other drivers handle exceptions. No suitable driver what’s wrong with my same code, no changes made Can jTDS be used in a multi threaded application?

Where does one place an instance name in the connect string?

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. If you can’t figure out why, ask your network administrator for help.

The number of statements that are kept open simultaneously can be controlled with the maxStatements parameter; see the jTDS URL format for more information. Indeed, some SQLExceptions are reported with a correct state code and some not. The JNetDirect license precludes publication of performance test results. 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.

Yes, i have put the corresponding class file to the path. These benchmarks are free to download so we encourage you to do it and run them yourself.

The above code was compiled successfully, but it’s not running. SSO in the distribution package for information on how to install it.


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.

Driver class, which means that jtds. In both cases if you call Statement. Without the native Ns library installed you still have to provide the username and com.internetcds.jdbc.tsd.driver because otherwise jTDS cannot determine user credentials. The name of the jTDS jar file may be jtds Normally, with a JDBC driver, PreparedStatement s are precompiled on creation, which gives increased performance if they are used a sufficient number of times.

Stored procedures should be invoked using the special JDBC call escape syntax. So for procedures returning ResultSet s you will have to loop, consuming all results before reading the output parameters i. Then i ns been connected with SQL Server As the server itself com.internetfds.jdbc.tds.driver 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 ”.
