Preface

Connection Interface


The Connection interface represents a connection with the database. SQL statements may be run in a connection session by using a Statement object. A Connection object is in auto-commit mode, by default. In the auto-commit mode, changes are committed to the database after an SQL statement is executed. The auto-commit mode can be modified by calling the setAutoCommit(boolean autoCommit) method. For example, auto-commit may be set to false :

connection.setAutoCommit(false);

If auto-commit is set to false, it would be required to commit changes by calling the commit() method:

connection.commit();

A Connection object can be set to read-only by calling the setReadOnly() method:

connection.setReadOnly(true);

If a Connection object is not required, close the connection by calling the close() method:

connection.close();

The following table discusses the methods in JDBC 4.0 that have been added to the Connection interface.
