Hi,

I've got a pretty hefty query, searching 1.5m rows, which was taking forever in the 'sending data' phase, so I've modified things to simply insert the results into a new table (to select later with a limit), using INSERT INTO ... SELECT.

However, when watching the process list, I still see this query 'sending data' - i don't want any data sent back.

I've tried both prepare_cached and a simple 'do', which I thought would be the solution, but to no avail.

Is there any way to speed this up? apart from indices of course?

Thanks
