NOTE: project has been moved from SourceForge to GitHub

Example:

// create connection pool
// This part depends on RDBMS
// MySQL driver - you can use PostgreSQL or SQLite instead as well
MySQLDriver driver = new MySQLDriver();
string url = MySQLDriver.generateUrl("localhost", 3306, "test_db");
string[string] params = MySQLDriver.setUserAndPassword("testuser", "testpassword");
// This part is common for all
DataSource ds = new ConnectionPoolDataSourceImpl(driver, url, params);

// creating Connection
auto conn = ds.getConnection();
scope(exit) conn.close();

// creating Statement
auto stmt = conn.createStatement();
scope(exit) stmt.close();

// execute simple queries to create and fill table
stmt.executeUpdate("CREATE TABLE IF NOT EXISTS ddbct1 (id bigint not null primary key AUTO_INCREMENT, name varchar(250), comment mediumtext, ts datetime)");
stmt.executeUpdate("INSERT INTO ddbct1 SET id=1, name='name1', comment='comment for line 1', ts='20130202123025'");
stmt.executeUpdate("INSERT INTO ddbct1 SET id=2, name='name2', comment='comment for line 2 - can be very long'");

// reading DB
auto rs = stmt.executeQuery("SELECT id, name name_alias, comment, ts FROM ddbct1 ORDER BY id");
while (rs.next())
    writeln(to!string(rs.getLong(1)) ~ "\t" ~ rs.getString(2) ~ "\t" ~ strNull(rs.getString(3)));
