Notas del editor
- Feedback!!!
- Nuair ar am,
- A few rounds with the ISO standards committee, and then:
- SQL:2003 Lots of "interesting" things added
- Joe Conway did this. It's still going.
- I did this with a lot of help from Andrew (RhodiumToad) Gierth. This was in 2004.
- Seven functions, maybe in Python!
- Thanks to George Courtsunis for the latest numbers. So we have good reasons to want to do things efficiently rather than with brute force.
- Six more functions!
- This is a WIP a.k.a. "Vaporware."
- This is broken, too. Shouldn't these be in contrib? They fit in terms of being version-dependent, at least until we get our API stabilized.
- SQL (Draft) Standard Ahead!
- Some of this makes sense. Why not regex match, or at least glob? What happens when the remote side doesn't have schemas per se?
- Actually, full compliance seems insane at first blush, but we can at least try for more.
- Feedback!
