• Custom aggregation in GROUP BY clause

  - by Rire1979

  If I have a table with a schema like this table(Category, SubCategory1, SubCategory2, Status) I would like to group by Category, SubCategory1 and aggregate the Status such that if not all Status values over the group have a certain value Status will be 0 otherwise 1. So my result set will look like (Category, SubCategory1, Status) I don't want to write a function. I would like to do it inside the query.

• Python regex compile (with re.VERBOSE) not working

  - by bfloriang

  I'm trying to put comments in when compiling a regex but when using the re.VERBOSE flag I get no matchresult anymore.

• Good Domain Driven Design samples

  - by jlembke

  I'm learning about DDD and enjoying every minute of it. However, there are some practical issues that are confusing to me that I think seeing some good samples might clear up. So being at peace with those issues, does anyone know of some good working code samples that do a good job of modeling basic DDD concepts? Particularly interested in An illustrative Domain Model Repositories Use of Domain/Application Services Value Objects Aggregate Roots I know I'm probably asking for too much, but anything close will help.

• linq get sum of two columns in one query

  - by Axarydax

  Hi, let's say that I have a table called Items (ID int, Done int, Total int) I can do it by two queries: int total = m.Items.Sum(p=>p.Total) int done = m.Items.Sum(p=>p.Done) But I'd like to do it in one query, something like this: var x = from p in m.Items select new { Sum(p.Total), Sum(p.Done)}; Surely there is a way to call aggregate functions from LINQ syntax...?

• Last matching symbol in Regex

  - by Menda

  I couldn't find a more descriptive title, but here there is an example: import re m = re.search(r"\((?P<remixer>.+) (Remix)\)", "Title (Menda Remix)") m.group("remixer") # returns 'Menda' OK m = re.search(r"\((?P<remixer>.+) (Remix)\)", "Title (Blabla) (Menda Remix)") m.group("remixer") # returns 'Blabla) (Menda' FAIL This regex finds the first parenthesis, and I would like to match the last parenthesis for always getting 'Menda'. I've made a workaround to this using extra functions, but I would like a cleaner and a more consistent way using the same regex. Thanks a lot guys.

• How to communicate between ASP.net custom controls

  - by ForeverDebugging

  I'm using two custom controls. One gathers the criteria for a search, and the other displays a list. These two controls need to remain seperate for the time being. What is the best method of transfering data from the search control, to the list control? I'm thinking of ViewState, Session or wrapping both within a UpdatePanel and using custom events??

• PHP convert external relative path to absolute path

  - by CMC

  Hello, I am trying to figure out how to convert an "external relative path" to an absolute one: I'd really like a function that will do the following: $path = "/search?q=query"; $host = "http://google.com"; $abspath = reltoabs($host, $path); And have $abspath equal to "http://google.com/search?q=query" The problem is that it is not guaranteed to be in that format, and it could already be absolute, or be pointing to a different host entirely, and I'm not quite sure how to approach this. Thanks.

• Keywords dictionary

  I developed a web site to search a database of videos indexed by keywords. There are several keywords that are repeated like "kid" and "kids" or "children" I'd like that when users search for a keyword they will find also videos with similar keywords and keywords translation (ex. "kid" "kinder"). I was thinking about using an external dictionary, there's Google dictionary but it does not provide APIs. Have you got any idea on how can I do that? Thanks Giuseppe
