![]() ![]() This property sets the duration the cleanup thread will keep running if there is nothing to clean up. The driver has an internal cleanup thread which monitors and cleans up unclosed connections. To do this, you use the DriverManager.getConnection() method:Ĭonnection db = DriverManager.getConnection(url, username, password)Īny reserved characters for URLs (for example, /, :, (, ),, &, #, =, ?, and space) that appear in any part of the connection URL must be percent encoded. To connect, you need to get a Connection instance from JDBC. The default is to connect to a database with the same name as the user name used to connect to the server. Defaults to the PostgreSQL® standard port number (5432).ĭatabase = The database name. Port = The port number the server is listening on. To specify an IPv6 address your must enclose the host parameter with square brackets, for example: jdbc:postgresql://:5740/accounting The parameters have the following meanings: With PostgreSQL®, this takes one of the following forms: With JDBC, a database is represented by a URL (Uniform Resource Locator). These older methods of loading the driver are still supported, but they are no longer necessary. Prior to Java 1.6, the driver had to be loaded by the application: either by calling Class.forName("") or by passing the driver class name as a JVM parameter java -Djdbc.drivers= example.ImageViewer The driver will be loaded by the JVM when the application connects to PostgreSQL® (as long as the driver’s jar file is on the classpath). Loading the DriverĪpplications do not need to explicitly load the class because the pgJDBC driver jar supports the Java Service Provider mechanism. How to connect to Cloud SQLĭatabase connections consume resources on the server and the connectingĪpplication.You should not import the org.postgresql package unless you are using PostgreSQL® extensions to the JDBC API. For more information, see Manage users with built-in authentication. For new instances, this means you must have configured Granting access to an application does not automatically enable a databaseīefore you can connect to an instance, you must have a database user account New customers also get $300 in free credits to spend on Cloud SQL to run, test, and deploy workloads. You can create an account to evaluate how Cloud SQL performs in real-world scenarios. Use the information that follows to decide which connection, authorization, andĪuthentication options work best for you.
