Find, Find Next on an index, in SQL?

Well your 15 years of using LIKE tells me tons, thanks.

My server size? Ha ! I’m on a Mac laptop and that’s it. There is not yet one client. I am starting out on learning SQL that’s all. I’m writing an app that’s intended to be my demo of my abilities once I get started, in a year maybe, on getting a client. I have no server. I’m using Postgres’s Mac app server to develop with. Small fry here, just a newbie to SQL. Know Omnis, don’t know SQL. I’m planning on servicing smaller companies so that I can remain a lone developer. Thank you for your answers. You’re very kind.

Quite the opposite—code that’s clean and east to test and maintain is far better than a tightly optimized pile of spaghetti.
