JDBC Driver

OrientDB is a NoSQL DBMS that support a subset of SQL ad query language.

Include in your projects

<dependency>
  <groupId>com.orientechnologies</groupId>
  <artifactId>orientdb-jdbc</artifactId>
  <version>1.7</version>
</dependency>

NOTE: to use SNAPSHOT version remember to add the Snapshot repository to your pom.xml.

How can be used in my code?

The driver is registered to the Java SQL DriverManager and can be used to work with all the OrientDB database types:

• memory,
• plocal and
• remote

The driver's class is com.orientechnologies.orient.jdbc.OrientJdbcDriver. Use your knowledge of JDBC API to work against OrientDB.

First get a connection

Properties info = new Properties();
info.put("user", "admin");
info.put("password", "admin");

Connection conn = (OrientJdbcConnection) DriverManager.getConnection("jdbc:orient:remote:localhost/test", info);

Then execute a Statement and get the ResultSet:

Statement stmt = conn.createStatement();

ResultSet rs = stmt.executeQuery("SELECT stringKey, intKey, text, length, date FROM Item");

rs.next();

rs.getInt("@version");
rs.getString("@class");
rs.getString("@rid");

rs.getString("stringKey");
rs.getInt("intKey");

rs.close();
stmt.close();

The driver retrieves OrientDB metadata (@rid,@class and @version) only on direct queries. Take a look at tests code to see more detailed examples.

Advanced features

Connection pool

By default a new database instance is created every time you ask for a JDBC connection. OrientDB JDBC driver provides a Connection Pool out of the box. Set the connection pool parameters before to ask for a connection:

Properties info = new Properties();
info.put("user", "admin");
info.put("password", "admin");

info.put("db.usePool", "true"); // USE THE POOL
info.put("db.pool.min", "3");   // MINIMUM POOL SIZE
info.put("db.pool.max", "30");  // MAXIMUM POOL SIZE

Connection conn = (OrientJdbcConnection) DriverManager.getConnection("jdbc:orient:remote:localhost/test", info);
