     * bindParam
     * Binds a PHP variable to a corresponding named or question mark placeholder in the 
     * SQL statement that was use to prepare the statement. Unlike Doctrine_Adapter_Statement_Interface->bindValue(), 
     * the variable is bound as a reference and will only be evaluated at the time 
     * that Doctrine_Adapter_Statement_Interface->execute() is called.
     *
     * Most parameters are input parameters, that is, parameters that are 
     * used in a read-only fashion to build up the query. Some drivers support the invocation 
     * of stored procedures that return data as output parameters, and some also as input/output
     * parameters that both send in data and are updated to receive it.

     * @param mixed $variable   Name of the PHP variable to bind to the SQL statement parameter.
     * @param integer $type     Explicit data type for the parameter using the Doctrine::PARAM_* constants. To return
     *                          an INOUT parameter from a stored procedure, use the bitwise OR operator to set the
     *                          Doctrine::PARAM_INPUT_OUTPUT bits for the data_type parameter.
     * @param integer $length   Length of the data type. To indicate that a parameter is an OUT parameter 
     *                          from a stored procedure, you must explicitly set the length.
     * @param mixed $driverOptions
     * @return boolean          Returns TRUE on success or FALSE on failure.
