Hi,

I am in the process to update an Arduino sketch in order to implement the connector 1.1. for Arduino.

My questions:

There are dynamically allocated and local, global (are they local AND global or local OR global, see Chuck's sample sketch "basic_select") cursors.

1. What is the difference concerning speed and memory footprint?
2. Which one is preferred for above mySQL statements?
3. Can local, global cursors be used in at least INSERT, UPDATE and SELECT queries (I guess yes)?
4. Are there any limitations for local, global cursors for other mySQL queries?

Thanks,
Kurt
