Connection URL sample
This Microsoft JDBC Driver for SQL Server sample application demonstrates how to connect to a SQL Server database by using a connection URL. It also demonstrates how to retrieve data from a SQL Server database by using a SQL statement.
The code file for this sample is named ConnectURL.java, and it can be found in the following location:
\<installation directory>\sqljdbc_<version>\<language>\samples\connections
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 sets various connection properties in the connection URL, and then calls the getConnection method of the DriverManager class to return a SQLServerConnection object.
Next, the sample code uses the createStatement method of the SQLServerConnection object to create a SQLServerStatement object, and then the executeQuery method is called to execute the SQL statement.
Finally, the sample uses the SQLServerResultSet object returned from the executeQuery method to iterate through the results returned by the SQL statement.
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class ConnectURL {
public static void main(String[] args) {
// Create a variable for the connection string.
String connectionUrl = "jdbc:sqlserver://<server>:<port>;encrypt=true;databaseName=AdventureWorks;user=<user>;password=<password>";
try (Connection con = DriverManager.getConnection(connectionUrl); Statement stmt = con.createStatement();) {
String SQL = "SELECT TOP 10 * FROM Person.Contact";
ResultSet rs = stmt.executeQuery(SQL);
// Iterate through the data in the result set and display it.
while (rs.next()) {
System.out.println(rs.getString("FirstName") + " " + rs.getString("LastName"));
}
}
// Handle any errors that may have occurred.
catch (SQLException e) {
e.printStackTrace();
}
}
}
