code: func (m *DbMap) Get(dest interface{}, keys ...interface{}) error {
  	return get(m, m, dest, keys...)
  }
docs: // Get runs a SQL SELECT to fetch a single row from the table based on the
  // primary key(s)
  //
  // dest should be an empty value for the struct to load.
  // keys should be the primary key value(s) for the row to load.  If
  // multiple keys exist on the table, the order should match the column
  // order specified in SetKeys() when the table mapping was defined.
  //
  // Hook function PostGet() will be executed
  // after the SELECT statement if the interface defines it.
  //
  // Returns a pointer to a struct that matches or nil if no row is found.
  //
  // Returns an error if SetKeys has not been called on the TableMap or
  // if any interface in the list has not been registered with AddTable.
