I know there are at least 10 different ways to structure project in version control. I'm curious what some methods being used are and which ones work for you. I've worked with SVN, TFS, and currently/unfortunately VSS. I've seen version control implemented very poorly and just OK, but never great.

How do I use T-SQL Group By |
|sql| |
I know I need to have (although I don't know why) an Order By clause on the end of a SQL query that uses any aggregate functions like count, sum, avg, etc:
select count(userID), userName from users group by userName
When else would GROUP BY be useful, and what are the performance ramifications? |
Counting the number of times tags are used might be a google example:
Select TagName,Count(*) As TimesUsed From Tags Group By TagName Order TimesUsed
If your simply wanting a distinct value of tags, I would prefer to use the distant statement.
Select Distinct TagName From Tags Order By TagName Asc |
GROUP BY also helps when you want to generate a report that will average or sum a bunch of data. You can GROUP By the Department ID and the SUM all the sales revenue or AVG the count of sales for each month. |
Group By forces the entire set to be populated before records are returned (since it is an implicit sort).
For that reason (and many others), never use a Group By in a subquery. |
If you are on Mac OSX, I found <a href = "http://www.versionsapp.com/">Versions</a> to be an incredible (free) GUI front-end to SVN. |

Pick your flavour of distributed version control. I like Mercurial, other folks swear by Git and Bazaar. There's no need to make a fake server to put a directory under version control, which, IMO, makes it very ideal for small projects.

To expand on what [Ben][1] said, it looks like they are milliseconds, and the display value is rounded slightly, possibly to the nearest 100 milliseconds and then 'cropped' to seconds. This would explain why 30533 is 30s and 70966 is 70s.
