Example:

import ddbc.core;
import ddbc.common;

// Create driver and fill connection params. You can leave only one section - for RDBMS you want to use
string[string] params;
// This part depends on RDBMS
version( USE_SQLITE )
{
    import ddbc.drivers.sqliteddbc;
    SQLITEDriver driver = new SQLITEDriver();
    string url = "zzz.db"; // file with DB
}
else version( USE_PGSQL )
{
    import ddbc.drivers.pgsqlddbc;
    PGSQLDriver driver = new PGSQLDriver();
    string url = PGSQLDriver.generateUrl( "/tmp", 5432, "testdb" );
    params["user"] = "hdtest";
    params["password"] = "secret";
    params["ssl"] = "true";
} else version(USE_MYSQL)
{
    import ddbc.drivers.mysqlddbc;
    // MySQL driver - you can use PostgreSQL or SQLite instead as well
    MySQLDriver driver = new MySQLDriver();
    string url = MySQLDriver.generateUrl("localhost", 3306, "test_db");
    params = MySQLDriver.setUserAndPassword("testuser", "testpassword");
}
// create connection pool
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)));
