DDBC - D DataBase Connector - abstraction layer for RDBMS access, with interface similar to JDBC.

Source file ddbc/drivers/pgsqlddbc.d. DDBC library attempts to provide implementation independent interface to different databases.

Set of supported RDBMSs can be extended by writing Drivers for particular DBs.

JDBC documentation can be found here: http://docs.oracle.com/javase/1.5.0/docs/api/java/sql/package-summary.html

This module contains implementation POD utilities.

import ddbc;
import std.stdio;

// prepare database connectivity
auto conn = createConnection("sqlite:ddbctest.sqlite");
scope(exit) conn.close();
Statement stmt = conn.createStatement();
scope(exit) stmt.close();
// fill database with test data
stmt.executeUpdate("DROP TABLE IF EXISTS user");
stmt.executeUpdate("CREATE TABLE user (id INTEGER PRIMARY KEY, name VARCHAR(255) NOT NULL, flags int null)");
stmt.executeUpdate(`INSERT INTO user (id, name, flags) VALUES (1, "John", 5), (2, "Andrei", 2), (3, "Walter", 2), (4, "Rikki", 3), (5, "Iain", 0), (6, "Robert", 1)`);

// our POD object
struct User {
    long id;
    string name;
    int flags;
}

writeln("reading all user table rows");
foreach(e; stmt.select!User) {
    writeln("id:", e.id, " name:", e.name, " flags:", e.flags);
}

writeln("reading user table rows with where and order by");
foreach(e; stmt.select!User.where("id < 6").orderBy("name desc")) {
    writeln("id:", e.id, " name:", e.name, " flags:", e.flags);
}
