Many thanks! It worked (unfortunately, I googled the solution of tuple_foreach). The code you posted is a way beyond my level of competence, yet I hope, I'll understand it and post a variation of it on codereview.stackexchange.com. It would be great if you could review it. — Nestor 49 secs ago

If it's working correctly, you might want to ask the codereview stack exchange site instead. Otherwise, you should at least explain what the code is supposed to do. — EOF 45 secs ago

@Peilonrayz I don't get it, how do you mean? Is there a guide how to do this somewhere?
 
@dfhwze No problem, there is a guide here or if you're like me and learn from code here at q.Id as "Post Link",.
 
@Peilonrayz That's so much easier, thanks

@Peilonrayz fwiw one would usually expect As [Post Link], because brackets are standard-conform

I had assumed that [] was the standard quoting, but apparently the double quotes are the standard

A: Is there a major RDBMS that DOESN'T allow column name quoting/escaping?

T.J. CrowderAs Leigh Riffel said, the answer to my question depends partially on what you mean by "major." I'm going with: No, there are no major RDBMS engines out there that can't handle name escaping/quoting. A quoted/escaped name is apparently properly called a delimited identifier. Martin Smith pointed...

ignore that, then, the brackets seem to be a microsoft thing

@Alexander: that could probably warrant its own question on codereview or stackoverflow, but in short: 1. your algorithm is O(kn) where k is the number of shifted elements and n is the length of the array. 2. Array.Copy is significantly faster than copying elements manually. 3. There's a lot of branching logic inside your loops. — Lorentz Vedeler 58 secs ago
