Missing LINQ?
-
Is anybody else more than just a little uneasy about LINQ? The few examples I've seen make no sense to me. And I can't see what drove them to this solution either. I picture somebody at MS saying "ya know, let's take this well known standardized perfectly good query language that everybody is used to, chuck it out the window, and make a cryptic bizzare syntax built into the language itsef..." Ok, I can see some advantages to having it built it to the languages, not least of all avoiding the need for string storage and manipulation. But could it not have been more... SQL-like? Am I alone here or does anybody else have reservations about LINQ? And I know there are some people out there that are really excited about it, I'd like to hear what they have to say too.

It doesn't worry me in the slightest. I won't be using it, so I don't really care about it one way or another. I'm a bit of a grumpy old git about "cutting edge" technologies. The problem with cutting edge is that they end up making you bleed.

Booo. I'd have to disagree here. It's reached a point (in the 2005 implementation) where I'm happy and comfortable with it. Now they just want to go and spoil it.

I would very much doubt that. LINQ is just syntactic sugar for a number of new classes that were added to the .NET Framework. You can perform the same thing but without using LINQ by just calling the appropriate methods. In fact that should be taught because it will show people how it is actually put together.

No. The basis of C# and SQL are different. SQL is mostly a declarative set based language, while C# is procedural. (i.e. In SQL you say what you want and the query optimiser figures out how to get it. In C# you specify HOW you want it to function.) You can view LINQ as a hybrid of the two.

My only reservation about LINQ is that I can see how newbies will be able to abuse it without fully understanding what is going on under the hood.

I'd have to disagree with that. I'm very happy with it. And I'm looking forward to the enhancements in 2008.

That's why they are also called "bleeding edge" ;)

So no change there then. God forbid that the unwashed masses should actually get off their a*ses and take the time to actually learn how to do something.

I'm not sure I'd agree with that. Even 1.0 was far more complete and polished than Java 1.2 at the time.

Not in the slightest. The only thing I'm worried about is that the concepts will be misunderstood and abused.
BoneSoft wrote:

There is a good overview of LINQ on MSDN[^] that provides some of the historical reasons that drove the implementation. In looking at the current and next generation of technologies, it has become apparent that the next big challenge in programming technology is to reduce the complexity of accessing and integrating information that is not natively defined using OO technology. The two most common sources of non-OO information are relational databases and XML. Rather than add relational or XML-specific features to our programming languages and runtime, with the LINQ project we have taken a more general approach and are adding general-purpose query facilities to the .NET Framework that apply to all sources of information, not just relational or XML data. This facility is called .NET Language-Integrated Query (LINQ).
BoneSoft wrote:

That's exactly what they were trying to avoid in the first place. Going beyond that, the SQL syntax is inheritantly different than C# and one of the goals was to allow programmers who do not know SQL to more easily work with data access. The thought behind this is that as a programmer, I should not be required to understand the nuances of the SQL language but I should still be able to interact with the data in a way that is natural to me (hence the C# syntax). LINQ is really just a structured mechanism of interacting with new functions and classes that have been added to the .NET Framework. Everything in a LINQ query is really nothing more than a function call. The way you interact and program a LINQ query is due to more basic additions to the language, such as extension methods, lambda expressions, and implicit typing. These concepts are not LINQ specific in that they can be used outside of LINQ, but without them LINQ wouldn't exist.

Absolutely, but we have that problem now so it will just be more of the same.

Maybe that's where most of my apprehension comes from, I don't like jumping into something I don't know how to use properly. And as a programmer, I don't like working with something I don't fully understand. But thanks for the info, now that I know there is an underlying model, I have something to go on, the examples I've seen seem to be complete giberish.

But then we'd all have to find real work to do instead of answering questions about how to create an array, telling people to do their own homework and what forums to post in. It would be a travesty! :)

Right now there isn't anyone at Microsoft focused specifically on LINQ and getting the word out about it. A lot of the examples try to show the "power" of LINQ, but don't do a good job at it because they are either hard to read/understand, incomplete, or don't show it in the context of a real-world scenario.

Yeah, that's always been one of the biggest problems. Xml serialization has bridged the XML gap somewhat, but database has always been a problem. And I'm not sure I like most current and past approaches to addressing that. I wasn't a huge EJB fan, but then again, I didn't do a lot of work with them. I suppose LINQ may be a step forward, but the syntax just looks so bizzare to me.

It's definately a step forward. I think we'll see a lot more improvements in the next release of the Framework (after 3.5). The syntax does take some getting used to, but I think once you do it will feel more natural than trying to write embedded SQL or dealing with SqlCommand objects.

I guess that makes sense. I suppose I should be content to do my thing for the time being and learn it when it's more main-stream. But lately I've been feeling like I'm falling behind. WPF is completely foreign to me still, as are most of the C# enhancements scheduled for 2008. Most of the enhancements in C# 2.0 made sense and were welcome changes. Most of what I've seen for 3.5 don't have the same appeal to me. It's like getting your new 2005 boss that does some great things for the department, then after a year brings in your new supervisor 2008 who likes to call you at 3 in the morning to make sure you're answering on-call pages. Just seems like something's wrong under the surface. Maybe I'm just getting old and set in may ways, which is something to guard against in this business. In any event, I guess it's comming. I'll have to deal with it when it releases anyway.

I don't know... Daniel Moth, one of the UK's DPEs, has done quite a good job in some of his presentations. http://www.danielmoth.com/Blog/2007/02/decomposing-linq.html[^] Skip to the last code sample to see what it looks like without LINQ. Daniel has got quite a good series of blog posts on LINQ. I've also got some information on LINQ and some of the new language constructs in C# 3.0: * Anonymous Types[^] * Method Extensions[^] * Automatic Properties[^] * A start on LINQ[^] * Object Initialisers I[^] * Object Initialisers II[^] * Object Initialisers III[^]
