This methods send data for a column (for example BLOB) for statement identified by statement_id. The param_id indicate which parameter the data belongs too. The data argument should be a file-like object. Since MySQL does not send anything back, no error is raised. When the MySQL server is not reachable, an OperationalError is raised. cmd_stmt_send_long_data should be called before cmd_stmt_execute.
