Can Access VBA Trigger a MySQL Event?

I have a bunch of update queries running on my MySQL server by means of an event set to every 15 seconds.  The event is called "Dashboard1" and it will clear the contents of a table then repopulate it with updated data by running about 95 update queries.

This works fairly well for the read only data I want to keep updated for the user, but it would be super useful if instead of using a timer, I could have the user trigger that set of update queries by telling the event to run when the update is actually needed.

Is there a way to do this with VBA?

Thanks,

David

Access can't trigger the event but you could add triggers to the MySQL table that would cause something to happen when a record is updated.

Or you could just call the Update queries as needed - or issue UPDATE statements against the connection to your MySQL database.

Hi Pat,

I think I see what you mean.  I just need a simple one field table with a integer field, which triggers my event on insert.  I can run one pass through query to insert a value, which triggers my 95 query event on the MySQL back end, then another to delete that record so nothing accumulates in that table.

This in effect would allow me to "CALL" the event from VBA by running that single append query.

I can do this with multiple events, I just need a trigger table for each one.

Sweet.....I like it!
