Performance Question

Question

Hi all,

I have a question as to whether a database will be able to 'handle' a piece of code (it is a MySQL database i.e. client-server model). The pseudocode:

foreach client
    update database with client details;

So, as it iterates through the clients, a simple UPDATE command is executed for each client. My question is, will there be any performance issue with this? Does the database need any kind of break in time between each UPDATE command, or can it handle being bombarded with the UPDATE statements at the high speed of the foreach loop?

My guess is that it can handle it, but I need to be sure and I don't have enough sample data to really test it. I am hoping this is an obvious question which someone can easily confirm, based on their experience.

Thanks
