https://dev.mysql.com/doc/refman/5.7/en/cursor-restrictions.html
The same restrictions apply to internal temporary tables created to hold the result set for a cursor as for other uses of internal temporary tables. Server-side cursors are implemented in the C API using the mysql_stmt_attr_set() function. A ...
