Let’s create a simple JDBC Example Project and see how JDBC API helps us in writing loosely-coupled code for database connectivity.īefore starting with the jdbc example, we need to do some prep work to have some data in the database servers to query. However for this solution, we should use database specific drivers, for example OJDBC jars provided by Oracle for Oracle DB and MySQL Connector/J for MySQL databases. This solution doesn’t require any extra APIs at the client side and suitable for database connectivity over the network.

We should have ODBC drivers installed in the machines from where we want to connect to database, that’s why this driver is almost obsolete and should be used only when other options are not available.

JDBC-ODBC Bridge plus ODBC Driver (Type 1): This driver uses ODBC driver to connect to database servers.As you've seen, you can connect to MySQL or any other database ( Postgresql, SQL Server, Oracle, etc.) using the usual Java JDBC technology from your Scala applications. If you were looking for a simple Scala JDBC connection example, I hope this short article was helpful. Val url = "jdbc:mysql://localhost/drupal7" Val url = "jdbc:mysql://hostname/database_name"Īnd if I was instead connecting to a database named drupal7, the MySQL URL would look like this instead: If you're new to JDBC and the MySQL URL shown above looks weird because I'm accessing the "mysql" database in the MySQL database server, remember that the general MySQL connection URL looks like this: Println("host, user = " + host + ", " + user)Īs you can see, this Scala JDBC database connection example looks just like Java JDBC, which you can verify from my very old JDBC connection example and JDBC SQL SELECT example. Val resultSet = statement.executeQuery("SELECT host, user FROM user") Val statement = connection.createStatement() create the statement, and run the select query there's probably a better way to do thisĬonnection = DriverManager.getConnection(url, username, password) connect to the database named "mysql" on the localhost * A Scala JDBC connection example by Alvin Alexander, In this example I'm connecting to a MySQL database server on my local computer, and then running a SQL SELECT query against the user table of the mysql database: Without any further introduction, here's the source code for a complete Scala class (an object, actually) that connects to a MySQL database using nothing but plain old JDBC. I just ran a simple JDBC connection and SQL SELECT test, and everything seems to work just as it does in Java. If you want to use a SQL database with your Scala applications, it's good to know you can still use the traditional Java JDBC programming library to access databases.
