Modifying Result Set Data Sample

DownloadDownload JDBC Driver

This Microsoft JDBC Driver for SQL Server sample application demonstrates how to retrieve an updateable set of data from a SQL Server database. Then, using methods of the SQLServerResultSet object, it inserts, modifies, and then finally deletes a row of data from the set of data.

The code file for this sample is named, and it can be found in the following location:

<installation directory>\sqljdbc_<version>\<language>\samples\resultsets


To run this sample application, you must set the classpath to include the sqljdbc.jar file or the sqljdbc4.jar file. If the classpath is missing an entry for sqljdbc.jar or sqljdbc4.jar, the sample application will throw the common "Class not found" exception. You will also need access to the AdventureWorks sample database. For more information about how to set the classpath, see Using the JDBC Driver.


The Microsoft JDBC Driver for SQL Server provides sqljdbc.jar and sqljdbc4.jar class library files to be used depending on your preferred Java Runtime Environment (JRE) settings. For more information about which JAR file to choose, see System Requirements for the JDBC Driver.


In the following example, the sample code makes a connection to the AdventureWorks sample database. Then, using an SQL statement with the SQLServerStatement object, it runs the SQL statement and places the data that it returns into an updateable SQLServerResultSet object.

Next, the sample code uses the moveToInsertRow method to move the result set cursor to the insert row, uses a series of updateString methods to insert data into the new row, and then calls the insertRow method to persist the new row of data back to the database.

After inserting the new row of data, the sample code uses an SQL statement to retrieve the previously inserted row, and then uses the combination of updateString and updateRow methods to update the row of data and again persist it back to the database.

Finally, the sample code retrieves the previously updated row of data and then deletes it from the database using the deleteRow method.
