Re: RawRow cross DB compatibility
Oscar, As an aside, I suggest you use Wonder’s features to implement the port, so you’re not stuck again with raw SQL. I would also bet that raw SQL has nothing to do with performance, but more with either: 1. A very complex query that cannot be translated into qualifiers (rare) 2. A developer that didn’t understand what was possible Fix it now, so you don’t have to fix it later! I learned so much good stuff about ERXKey lately!

Re: RawRow cross DB compatibility
Hi Ken, Actually there are many queries that are impossible to do with the set of tools that Apple gives us. We *can* write special qualifiers but it takes time and is a bit daunting to get up to speed with. A surprisingly large set of these “unsolvable” problems can be overcome with a custom “Exists” qualifier which is what I’ll present at WOWODC. But you are right on the money, “performance” is often a cop-out for “I don’t understand” how to do it a better way so I roll up my sleeves and write it in straight SQL. I mean, heck, EOF lets us pass hints down to SQL if we want to.

RawRow cross DB compatibility
Hi all, I'm migrating a few projects from Oracle to Postgresql, there are a lot straight RawRow for performance. Now I'm facing the problem of changing every incompatibility like nvl for coalesce for example. 1.
