As I do use a case-sensitive collation, it forces me to be consistant with naming of variables, tables, columns, etc.
Okay, so I have to be honest and say that I'm not always consistent with case because I don't work with any case-sensitive collations. That's one of things I hate about the C-based languages and love about VB, I don't have to worry about case there either. Although I now have RedGate SQLPrompt and SQLRefactor which aids in consistency with case especially.
This is also one of the reasons I argue for using "_" as a separator instead of using the hungarian notation or Camel Case.

Here is a compilation of the 5 best standards I have come across:
1. Don't foist standards on others.
2. See above.
3. On Monday to Friday, see above.
4. Over the weekend, see above.
5. When considering creating standards, see above.

I think Best Practices need to follow the 80/80/20/20 rule. What makes sense 80% of the time for 80% of the people is what we should recommend.
Or as Andy Warren puts it, do this default until you know why you shouldn't

With all due respect, I disagree. In SSC, yea you are right or maybe right. But not in your own DB at your work place. If you want to see that your DB is working in the optimal way, you should have some basic standards that you enforce on the DB objects that you or your developers create.

I actually prefer OrderHeader to order_header. I'll use the '_' in some cases, but shy away from it in naming tables, views, columns. I am also big on white space. I actually hate code that uses something like this: where cola=colb. Please, white space helps make code more readable, don't you agree?
Again, what it really comes down to when posting code is be consistant in what you do. I try to be consistant, and for me using a case-sensitive collation helps, plus we have PeopleSoft software for finance and hr, and it uses the Latin1_General_BIN collation.

What is "best practices" actually? What is "best" today may not be "best" a week, or month, or year from now.
Which is one of the reasons I use the term 'recommended practice' and not 'best practice'

And yet one more example of things "getting worse"

I agree with Jack and Barry. Yes, I try to post that way all the time. No, I don't think we need to get into sweating standards like that.Don't you get the impression sometimes that the OP's want his query / sproc / function whatever to look as big and complicated as possible? Quite often I take the time to convert a chunk of code to using table aliases simply so I can get it small enough to reel the whole thing into my walnut-sized brain, but the OP's often completely ignore it. 'Course it's 'good practice', but it don't half help to follow what a bit of code is supposed to be doing!
Nevertheless, I'd stick with Grant on this one and keep it voluntary. It's all part of the learning curve innit.
I'll do the same thing. Plus I use Red Gate's SQL Prompt to reformat their stuff to make it more readable just for me, but that has the added benefit of making everything look pretty consistent. Now if I can get in the habit of using the spell checker as consistently.

Steve, does that mean that this thread is not a good place for me to ask about that annoying little knock in my engine between 60-65 miles per hour?

Yeah, I've received one or two of those on my blog recently. It does seem like people are getting more desperate for this information but just don't have a clue how to go about getting it.

Don't you get the impression sometimes that the OP's want his query / sproc / function whatever to look as big and complicated as possible?
When I see big honking strings of fully qualified table names and "odd" formatting, I usually assume that some query-generating software is the real author.

How true. PeopleSofts tools create poorly formatted SQL code. If I need to review that code, the first thing I have to do is reformat it so I can read it easier.

Welcome to megalomaniacs central, folks!
Don't bother us with your petty sql statements, do not ask us questions without reading the dozen or so best practice documents; blogs and forums and, above all, never do anything outside our standards and waste our valuable time - that we do not like.
We also strongly suggest that you take our carefully thought through standards to your workplace and imply that any colleague that doesn't study and use them is somehow inferior.

I have to admit to being lazy about formatting and capitalization. I have a relatively consistent format, but I can't say that it's the easiest to read.

And this is one of the things that makes SQLPrompt and SQLRefactor so nice. I still need to figure out how to get it to format exactly to my preferences. Right now it is just close. I'm having to rethink my preferences because the tool does it just a bit differently.
Oh and I am with you on the whole white space issue. I typically have a lot in my code.
