Retrieving result set data sample
This Microsoft JDBC Driver for SQL Server sample application demonstrates how to retrieve a set of data from a SQL Server database, and then display that data.
The code file for this sample is named RetrieveResultSet.java, and it can be found in the following location:
\<installation directory>\sqljdbc_<version>\<language>\samples\resultsets
Requirements
To run this sample application, you must set the classpath to include the mssql-jdbc jar file. You'll also need access to the AdventureWorks2022 sample database. For more information about how to set the classpath, see Using the JDBC Driver.
Note
The Microsoft JDBC Driver for SQL Server provides mssql-jdbc 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.
Example
In the following example, the sample code makes a connection to the AdventureWorks2022 sample database. Then, using a SQL statement with the SQLServerStatement object, it runs the SQL statement and places the data that it returns into a SQLServerResultSet object.
Next, the sample code calls the custom displayRow method to iterate through the rows of data that are in the result set, and uses the getString method to display some of the data.
