The Web that is today was once envisioned as an “information super-highway” when in fact, it is much closer to an information garbage dump rather than any super-highway. Not only is the Web choked with misinformation, those who cannot write well and don’t take the time to edit and proof their postings just add to the garbage heap and more importantly, tarnish their own image in whatever they are presenting.
Those upset about the grammar in this article ARE correct and though SSC might be held somewhat liable for not editing content, it’s really up to the author who in this case, should have gotten his/her posting proofed first.
It is totally ridiculous to make statements like "...try posting on a web site not in your native language..." – the people making that comment miss the point – this author chose to post on SSC and thus he/she was placing something in the public arena for consumption by English readers, and therefore they should have taken the time to get it proofed and by not doing so, whether the content was good or not, they come off looking lazy to English readers, and distracting from the very content they are presenting.
As for the explanation of Inner Joins themselves, the article is very basic and though for some that might be helpful, it was not very "real world" and did more to explain the uses of operators ( = ) than Inner Joins. Those of us doing lots of SQL day to day with multiple Inner Joins could have benefitted much more from a slightly more advanced discussion than this beginner’s level stuff. Though the author should be credited that he/she did a fair presentation of Inner Joins 101 - the operators and their effects - the content presented in that vein seemed to me to be more along the lines of something someone would learn on Day 1 of a beginners SQL class. I suppose there is value in that for some, but I have found so much great content on SSC that this post seemed almost out of place – just a little beyond someone pointing out that you need a computer and MS SQL to do SQL. Oh, and don’t forget, electricity too!
SSC is one of the best sites for SQL on the Web – I commend the site! But, imagine if every posting on the SSC was poorly worded or lacked proper grammar, and the content was mere “fluff”. THAT would not be a good thing.
Hence, presentation matters, content matters. The Web will be what we make it – garbage dump, or information super-highway.
There's no such thing as dumb questions, only poorly thought-out answers...
