Monday, February 28, 2005Flattening Out Data with One of the Coolest SQL Tricks Ever
This is sweet...
Tuesday, February 15, 2005Return a delimited list of child values in your SQL. For report-loving folks, or others. Firefox Speed Tips
From Firefox Tuning - MozillaZine Forums...
Monday, February 07, 2005Type "about:config" in your FireFox address bar, then make the following changes: network.http.pipelining = true network.http.maxrequests = 8 network.http.proxy.pipelining = true browser.turbo.enabled = true Note that the above changes should result in a visible speedup (they did for me), but you may experience some display glitches or other issues on a few sites. If you have too many problems, revert the above parameters to their original settings. Log Parser 2.2 Released!
Finally, Log Parser 2.2 has been released. If you didn't know, LogParser is a great little tool that will rip through log files & delimited data files (Event logs, IIS logs, CSV, etc) & allow you to execute SQL-like queries against the data. It even has a COM interface.
Tuesday, February 01, 2005The new version, 2.2, supports some new data types & SQL commands, and also will generate graphs based on query results, e.g. to calculate the distribution of the HTTP response status codes from your IIS log files: C:\>LogParser "SELECT sc-status, COUNT(*) AS Times INTO Chart.gif generates this ![]() The above example is from the logparser examples page. So, if you have a bunch of log files & want to run some easy queries against it, check out logparser. Another test site
Again, in the vegas theme... :)
Test site
I recently realized that I could probably put together a few small sites using the tech I developed for development now. I've received numerous comments from visitors saying how the arrangement & information helps them find the information they need, so I might as well leverage it to help out people in other areas. So the first of those sites is blackjackjungle. I'll use it as a testbed for tech & ideas, since I don't want to mess with developmentnow too badly. Plus, I visited vegas recently, and let's just say I stink at blackjack & poker. I didn't want to play slots, and I'd be afraid to visit most gambling sites (popups, spyware, etc.). So a nice forums site focused on content & information exchange would be a nice thing. Hence my new site.
An aside -- if you visit blackjackjungle you'll notice a number of ads for the jungle book and other jungle-related stuff. I stripped out the word jungle everywhere I could, but apparently some of my pages are unclear enough that Google latches onto the word "jungle" in the domain name. So a word to the wise -- when you're picking out a domain name, be careful what you choose. Because it could come back to bite you (in the jungle). :) SQL Server timestamp column
SQL Server 7/2000 supports a column type of timestamp. A table can only have one timestamp column, and you cannot set its value directly. Instead, a timestamp column's value is automatically updated whenever a record is inserted or updated.
However -- and this is the part that threw me off initially -- the actual value of a timestamp column is not a date, not a datetime. It has nothing to do with time at all. Instead, a timestamp column contains abinary number value. That value is incremented automatically when a record is updated. It's best to think of it as a version or revision number. So...when you create a timestamp column, make sure to name it something like Revision, Version, something. B/c I guarantee if you call is timestamp, you'll confuse someone. At least initially. :) If you want a datetime column (e.g. LastUpdateDate) that is automatically updated when you insert and update a row, you can give it a default value of getdate(), and add an update trigger on that table that updates the value to getdate() or something. If you hate triggers (or need to avoid them for performance reasons), I guess you could just ensure that every proc & application that modifes the record also updates your LastUpdateDate column. But I think a trigger would be simpler & safer in most cases. Archives September 2004 October 2004 November 2004 December 2004 January 2005 February 2005 March 2005 April 2005 May 2005 |
