Example

C++

#include <dboo/odb.h>
#include <fstream>

int main() {

    dboo::odb db;

    db.connect("localhost", 8823,
              "my_database",
              "usr132",
              "password");

    std::ifstream in{"mydata.bak"};
    db.restore_database(in, restore_options::json);

    return 0;
}

Node.js

const dboo = require('dboo');
const config = require('config');

dboo.argv(process.argv);

dbConfig = config.get('dbConfig');

dboo.init(); // Class declarations must come before init!

const db = new dboo.odb();
db.connect(dbConfig.host, Number(dbConfig.port),
            dbConfig.dbName, dbConfig.webUserName,
            dbConfig.webUserPwd);

db.restore_database("mydata.bak");
