postgresqlHow do I use the PostgreSQL JDBC driver?
The PostgreSQL JDBC driver is a Java library used to connect to a PostgreSQL database. To use it, you must include the driver jar in your classpath and then use the JDBC API to create a connection.
Example code
// Load the PostgreSQL JDBC driver
Class.forName("org.postgresql.Driver");
// Establish a connection
String url = "jdbc:postgresql://localhost:5432/dbname";
String username = "username";
String password = "password";
Connection conn = DriverManager.getConnection(url, username, password);The code above:
- Loads the PostgreSQL JDBC driver class
org.postgresql.Driver. - Establishes a connection to a PostgreSQL database using the
DriverManager.getConnection()method. This method takes the database URL, username, and password as parameters.
