The following is an example of the format of a URL specifying user name and password when using Oracle JDBC drivers, in this case the JDBC Thin driver: connection object ( Connection)

URL ( String fully specifying connection and including user name and password), auto-commit setting ( boolean)

URL ( String), object, auto-commit ( boolean) URL ( String), user name ( String), password ( String), auto-commit ( boolean) The different input parameter sets for these constructors are: However, if you want to create an instance directly, then there are five constructors for DefaultContext. It is typical to instantiate DefaultContext using the nnect() or Oracle.getConnection() method. In the Oracle JDBC implementation, the default for the auto-commit flag is true. However, anytime you use a constructor to create an instance of a connection context class, including DefaultContext, you must specify the auto-commit setting. If that is the setting you want, then you can use one of the signatures that does not take auto-commit as input. For the nnect() and Oracle.getConnection() methods only, the default is false. The auto-commit flag specifies whether SQL operations are automatically committed. When you inherit a connection, you will also inherit the auto-commit setting of that connection. These last two signatures inherit an existing database connection. The following is an example of the format of a URL string specifying user name ( HR) and password ( hr) when using Oracle JDBC drivers, in this case the JDBC Thin ( String), auto-commit flag ( boolean)Ī object for the class relative to which the properties file is loaded, name of properties file ( String)Ī object, name of properties file ( String), auto-commit flag ( boolean)Ī object, name of properties file ( String), user name ( String), password ( String)Ī object, name of properties file ( String), user name ( String), password ( String), auto-commit flag ( boolean) URL ( String) fully specifying the connection, including user name and password URL ( String), object, auto-commit flag ( boolean) URL ( String), object containing properties for the connection URL ( String), user name ( String), password ( String), auto-commit flag ( boolean) URL ( String), user name ( String), password ( String) For Oracle, there is an implicit COMMIT when a connection is closed, and an implicit ROLLBACK when a connection is garbage-collected without being closed, but it is not advisable to rely on these mechanisms.īoth the method have signatures that take the following parameter sets as input: Whether there would be an implicit COMMIT operation as the connection is closed is not specified in the JDBC standard and may vary from vendor to vendor. Or, to close the default connection, the Oracle class also provides a close() method:Īlways commit or roll back any pending changes before closing the connection. When you want to use the default connection, it is not necessary to specify a connection context: #sql Alternatively, you can use name-value pairs.Ĭtx could also use the HR/ hr schema, if you want to perform multiple sets of operations on the same schema. In using the JDBC OCI driver, no service name (or SID) is required if you intend to use the default account of the client, as will be the case in examples in this document. Also, the database must have a listener running at the specified port. Note that in using a JDBC Thin driver, the URL must include the host name, port number, and service name (or SID, which is deprecated in Oracle Database 12 c Release 2 (12.2)), as in the preceding example. Once you have completed these steps, you do not need to specify the connection for any of the SQLJ executable statements in your application, if you want them all to use the default connection. It is not necessary to do anything with this DefaultContext instance directly.

In this example, the connection will use the JDBC Thin driver to connect the HR user with the password, hr, to a database on the computer, localhost, through port 5221, where myservice is the name of the database service for the connection.Įither of these examples creates a special static instance of the DefaultContext class and installs it as your default connection.

In this example, you must also import the class.Īlternatively, you can specify user name, password, and URL directly: 'HR', 'hr') If you use connect.properties, then you must edit it appropriately and package it with your application. In the example, if M圜lass is located in my-package, then connect.properties must be found in the same package location, my-package. The connect.properties file is searched for relative to the specified class.
