Developing Linq to LLBLGen Pro, part 10

(This is part of an on-going series of articles, started here ) Whoa, almost a month without an update! The truth is that I wanted to finish GroupBy support before posting another article in this ongoing series, and it took almost 3 weeks to get it right. But more on that later, first some easy stuff...

Developing Linq to LLBLGen Pro, day 2

(This is part of an on-going series of articles, started here ) Adding Linq support to an O/R mapper like LLBLGen Pro is a matter of choice: either you implement new SQL engines or you convert the expression trees to native query language components. The former is a lot more work and the latter will...

Developing Linq to LLBLGen Pro, Day 1

(This is part of an on-going series of articles, started here ) I didn't have that much time today to work on our Linq to LLBLGen Pro layer, but nevertheless there are a couple of interesting things to mention. . It's all about the Source, Luke Let's look at a skeleton of a very simple Linq query: /...

Developing Linq to LLBLGen Pro, Day 0

Now v2.5 of LLBLGen Pro is out the door and the release-stress has gone away, it's time to pick up the next project, which is Linq support for LLBLGen Pro, which will be rolled into v2.6 of LLBLGen Pro, which is scheduled for Q4 2007. This time around, we thought it would be fun to blog a post on every...

Developing Linq to LLBLGen Pro, part 12

(Updated Wednesday 30-jan-2008). It was mentioned that we would implement 'Skip' as well, although we already had a paging method added, TakePage(). After carefull analysis, we decided not to implement Skip for now. The reason is that it can lead to confusing queries, while paging is what the developer...

Developing Linq to LLBLGen Pro, part 13

(This is part of an on-going series of articles, started here ) Last time I talked about implementing Single. It turned out to be fairly straightforward, but as I explained in the previous episode, it's a weird method and has different behavior related to where it's used in the query: sometimes it does...

Developing Linq to LLBLGen Pro, part 14

Update: I made a mistake in the first Linq to Sql query. It's not that slow as I previously posted. I didn't filter on country, which made it pull the rows of all 91 customers into memory instead of the 11. Fetching 91 customer rows, 818 order rows and 2015 order details rows took Linq to Sql over 900ms...
