Example: Simple SELECT statement implementation in node-oracledb

var oracledb = require('oracledb');

oracledb.getConnection(
  {
    user          : "hr",
    password      : "welcome",
    connectString : "localhost/XE"
  },
  function(err, connection)
  {
    if (err) {
      console.error(err.message);
      return;
    }
    connection.execute(
      "SELECT department_id, department_name "
    + "FROM departments "
    + "WHERE department_id = :did",
      [180],
      function(err, result)
      {
        if (err) {
          console.error(err.message);
          return;
        }
        console.log(result.rows);
      });
  });

With Oracle's sample HR schema, the output is:

[ [ 180, 'Construction' ] ]

There are more examples in the examples directory.
