问题 Is it possible to sort multiple dimensional array by multiple columns using natural sort in PHP? Here is an example. Suppose I have a 2D array of data, e.g., $array[1]['Name'] = 'John'; $array[1]['Age'] = '20'; $array[1]['Code'] = 'ABC 12'; $array[2]['Name'] = 'John'; $array[2]['Age'] = '21'; $array[2]['Code'] = 'ABC 1'; $array[3]['Name'] = 'Mary'; $array[3]['Age'] = '20'; $array[3]['Code'] = 'ABC 10'; I want to sort this array by name (ASC), then by age (DESC), and by code (ASC), all will be

问题 This question already has answers here : Natural Sort Order in C# (17 answers) Closed 2 years ago . What's the easiest way to get a LINQ query (from an SQL database - does that matter?) to order strings naturally? For example, I'm currently getting these results: Project 1 Project 10 Project 2 What I'd like is to see is this: Project 1 Project 2 Project 10 The query I'm using is this: return from p in dataContext.Projects orderby p.Name select p; 回答1: There is no built-in way to do this using

问题 I've got a Postgres ORDER BY issue with the following table: em_code name EM001 AAA EM999 BBB EM1000 CCC To insert a new record to the table, I select the last record with SELECT * FROM employees ORDER BY em_code DESC Strip alphabets from em_code usiging reg exp and store in ec_alpha Cast the remating part to integer ec_num Increment by one ec_num++ Pad with sufficient zeors and prefix ec_alpha again When em_code reaches EM1000, the above algorithm fails. First step will return EM999 instead

问题 I'm looking for the easiest way to sort an array that consists of numbers and text, and a combination of these. E.g. '123asd' '19asd' '12345asd' 'asd123' 'asd12' turns into '19asd' '123asd' '12345asd' 'asd12' 'asd123' This is going to be used in combination with the solution to another question I've asked here. The sorting function in itself works, what I need is a function that can say that that '19asd' is smaller than '123asd'. I'm writing this in JavaScript. Edit: as adormitu pointed out,

问题 One of my columns in a SQL Server 2005 table contains alphanumeric values and I want to sort the rows as per the alphanumeric sorting. HOUSE_NO is a NVARCHAR column and it contains values like this: - 2/1 NAWOG - 1/1 - 2/1 A - 1/2 A GOLCHA - 1 - 2 - SHASWAT KUTIR - 3 A - 11/1 - 11 And I want them to be sorted as: - 1 - 1/1 - 1/2 A GOLCHA - 2 - 2/1 A - 2/1 NAWAG - 3 A - 11 - 11/1 - SHASWAT KUTIR I have tried many methods but not successful. I need your suggestions 回答1: Yuck. This is not

问题 Summary: after I gem install <gem_name> , how do I make it extend Array which the gem can do? Details: I see a gem for "natural language sort", which is http://rubygems.org/gems/naturalsort http://naturalsort.rubyforge.org/ so I am using Ruby 1.9.2 and Rails 3.0.6, and I add the line gem 'naturalsort' into Gemfile , and do a bundle install and restart the server, but now, for some reason, I still can't do a NaturalSort::naturalsort ['a', 'b', 'c', 'd', 'A', 'B', 'C', 'D'] in my helper file?

问题 A previous stackoverflow question explains how to sort a list of strings alpha-numerically. I would like to sort a list of tuples alphanumerically by the tuple's first element. Example 1: >>> sort_naturally_tuple([('b', 0), ('0', 1), ('a', 2)]) [('0', 1), ('a', 2), ('b', 0)] Example 2: >>> sort_naturally_tuple([('b10', 0), ('0', 1), ('b9', 2)]) [('0', 1), ('b9', 2), ('b10', 0)] Update: To emphasize the alphanumeric factor, please review example 2. 回答1: Using the second answer from the other

问题 I am reading a directories content using QDir::entryList() . The filenames within are structured like this: index_randomNumber.png I need them sorted by index , the way the Windows Explorer would sort the files so that I get 0_0815.png 1_4711.png 2_2063.png ... instead of what the sorting by QDir::Name gives me: 0_0815.png 10000_6661.png 10001_7401.png ... Is there a built-in way in Qt to achieve this and if not, what's the right place to implement it? 回答1: If you want to use QCollator to

问题 I have written a comparator to sort the collection based on "id" like this: comparator: function(coll) { return coll.get('id'); } This works fine for input: "id-1, id-0, id-2, id-199" to sort as "id-0, id-1, id-2, id-199" But does not sort numerically here: "id-1, id-0, id-2, id-199, id-99" as "id-0, id-1, id-2, id-199, id-99" -- id-99 should be before id-199. 回答1: As commented by @suish the way this was solved was by performing a replace of all non-numerical part with empty string. coll.get(

问题 Similar Questions Similar questions have been asked before, but always have specific qualities to the data which allow a more targeted "split it up and just sort by this part" approach, which does not work when you don't know the structure of the data in the column - or even the column, frankly. In other words, not a generic, "Natural" sort order - something roughly equivalent to SELECT * FROM [parts] ORDER BY [part_category] DESC, [part_number] NATURAL DESC My Situation I have a DataView in
