  • Aggregate Functions on subsets of data based on current row values with SQL

    - by aasukisuki
    Hopefully that title makes sense... Let's say I have an employee table: ID | Name | Title | Salary ---------------------------- 1 | Bob | Manager | 15285 2 | Joe | Worker | 10250 3 | Al | Worker | 11050 4 | Paul | Manager | 16025 5 | John | Worker | 10450 What I'd like to do is write a query that will give me the above table, along with an averaged salary column, based on the employee title: ID | Name | Title | Salary | Pos Avg -------------------------------------- 1 | Bob | Manager | 15285 | 15655 2 | Joe | Worker | 10250 | 10583 3 | Al | Worker | 11050 | 10583 4 | Paul | Manager | 16025 | 15655 5 | John | Worker | 10450 | 10583 I've tried doing this with a sub-query along the lines of: Select *, (select Avg(e2.salary) from employee e2 where e2.title = e.title) from employee e But I've come to realize that the sub-query is executed first, and has no knowledge of the table alias'd e I'm sure I'm missing something REALLY obvious here, can anyone point me in the right diretion?

  • Is there a way to generate a short random id, avoiding collisions, without hitting persistent storag

    - by bshacklett
    If you've used GoToMeeting, that's the type of ID I want. I'd like it to be random so that it obfuscates the number of items being tracked and short, so that it's easy to reference manually; UUIDs are way too long. I'd like to avoid hitting persistent storage merely for performance reasons, but I can't think of any other way to avoid collisions. Is 9 digits enough to do something time-based?

  • can i use MAX function for each tuple in the retrieved data set

    - by kshama
    Hi, My table result contains fields: id count ____________ 1 3 2 2 3 2 From this table i have to form another table **score** which should look as follows id my_score ___________ 1 1.0000 2 0.6667 3 0.6667 That is my_score=count/MAX(count) but if i give the query as create TEMPORARY TABLE(select id,(count/MAX(count)) AS my_score from result); only 1 st row is retrieved.Can any one suggest the query so that my_score is calculated for all tuples. Thanks in advance.

  • Problem pulling data from website in .NET and C#

    - by Cptcecil
    I have written a web scraping program to go to a list of pages and write all the html to a file. The problem is that when I pull a block of text some of the characters get written as '?'. How do I pull those characters into my text file? Here is my code: string baseUri = String.Format("http://www.rogersmushrooms.com/gallery/loadimage.asp?did={0}&blockName={1}", id.ToString(), name.Trim()); // our third request is for the actual webpage after the login. HttpWebRequest request = (HttpWebRequest)WebRequest.Create(baseUri); request.Method = "GET"; request.UserAgent = "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1)"; //get the response object, so that we may get the session cookie. HttpWebResponse response = (HttpWebResponse)request.GetResponse(); StreamReader reader = new StreamReader(response.GetResponseStream()); // and read the response string page = reader.ReadToEnd(); StreamWriter SW; string filename = string.Format("{0}.txt", id.ToString()); SW = File.AppendText("C:\\Share\\" + filename); SW.Write(page); reader.Close(); response.Close();

  • Curve fitting: Find a CDF (or any function) that satisfies a list of constraints.

    - by dreeves
    I have some constraints on a CDF in the form of a list of x-values and for each x-value, a pair of y-values that the CDF must lie between. We can represent that as a list of {x,y1,y2} triples such as constraints = {{0, 0, 0}, {1, 0.00311936, 0.00416369}, {2, 0.0847077, 0.109064}, {3, 0.272142, 0.354692}, {4, 0.53198, 0.646113}, {5, 0.623413, 0.743102}, {6, 0.744714, 0.905966}} Graphically that looks like this: And since this is a CDF there's an additional implicit constraint of {Infinity, 1, 1} Ie, the function must never exceed 1. Also, it must be monotone. Now, without making any assumptions about its functional form, we want to find a curve that respects those constraints. For example: (I cheated to get that one: I actually started with a nice log-normal distribution and then generated fake constraints based on it.) One possibility is a straight interpolation through the midpoints of the constraints: mids = ({#1, Mean[{#2,#3}]}&) @@@ constraints f = Interpolation[mids, InterpolationOrder->0] Plotted, f looks like this: That sort of technically satisfies the constraints but it needs smoothing. We can increase the interpolation order but now it violates the implicit constraints (always less than one, and monotone): How can I get a curve that looks as much like the first one above as possible? Note that NonLinearModelFit with a LogNormalDistribution will do the trick in this example but is insufficiently general as sometimes there will sometimes not exist a log-normal distribution satisfying the constraints.

  • C# udp can not receive any data

    here is my code Socket sck = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp); sck.Bind(new IPEndPoint(IPAddress.Any, 0)); // Broadcast to find server string msg = "Imlookingforaserver:" + udp_listen_port; byte[] sendBytes4 = Encoding.ASCII.GetBytes(msg); IPEndPoint groupEP = new IPEndPoint(IPAddress.Parse("255.255.255.255"), server_port); sck.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.Broadcast, 1); sck.SendTo(sendBytes4, groupEP); //Wait response from server Socket sck2 = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp); sck2.Bind(new IPEndPoint(IPAddress.Any, udp_listen_port)); byte[] buffer = new byte[128]; EndPoint remoteEndPoint = new IPEndPoint(IPAddress.Any, udp_listen_port); sck2.ReceiveFrom(buffer, ref remoteEndPoint); //<<< I never pass this line I use above code to try find a server. First i broadcast a message and then i wait response from server. A test i made with the server written in c++ and running in windows vista, client written in C# and run on the same machine with server. Problem is: The server can receive message which client broadcast. But client can not receive anything from server. I try to write a client with c++ and it work like a charm, i think my problem is in C# client.

  • How do I Data-Bind dual DateTimePicker to a single DateTime object

    - by S.C. Madsen
    Hi, I have a simple form, with two DateTimePicker-controls: One for date, and one for time. The thing is these two controls are supposed to represent a single point in time. Hence I would like to "Bind" them to a single DateTime property on my form (for simplicity). I did the following: // Start is a DateTime property on the form _StartDate.DataBindings.Add("Value", this, "Start"); _StartTime.DataBindings.Add("Value", this, "Start"); But hooking into "ValueChanged" event, yields mixed results... Sometimes I get exactly what I want, sometimes the updates of the property are "sluggish". I figured this way of splitting into two DateTimePicker's was fairly common. So how to do it? Update: There is possibly multiple questions in there: How do I bind a DateTimePicker (Format: Date) to a DateTime Property on a form? Then, how do I bind yet another DateTimePicker (Format: Time) to the same property? I'm using Visual Studio Express 2008 (.NET 3.5), and I seemingly get ValueChanged events from the DateTimePickers before the value is changed?

  • Show last command with up arrow on a linux c shell

    - by nunos
    I have implemented a simple linux shell in c. Now, I am adding some features and one I immediately thought about was to be able to show the last commands with the up arrow. Question 1: However, I have no idea how to accomplish this. Do you? Question 2: Any comment on how to store the "history" commands are also appreciated. I suppose something like a queue which allows access to all elements would be a good idea. Am I wrong? Do I have to implement it or is there already some good implementation out there I should know about? Thanks.

  • How to make images hosted on Amazon S3 less public but not completely private?

    - by Jay Godse
    I fired up a sample application that uses Amazon S3 for image hosting. I managed to coax it into working. The application is hosted at github.com. The application lets you create users with a profile photo. When you upload the photo, the web application stores it on Amazon S3 instead of your local file system. (Very important if you host at heroku.com) However, when I did a "view source" in the browser of the page I noticed that the URL of the picture was an Amazon S3 URL in the S3 bucket that I assigned to the app. I cut & pasted the URL and was able to view the picture in the same browser, and in in another browser in which I had no open sessions to my web app or to Amazon S3. Is there any way that I could restrict access to that URL (and image) so that it is accessible only to browsers that are logged into my applications? Most of the information I found about Amazon ACLs only talk about access for only the owner or to groups of users authenticated with Amazon or AmazonS3, or to everybody anonymously.

  • WPF: Editable ComboBox; how to make search/auto-fill functionality case sensitive?

    - by unforgiven3
    Say I have a ComboBox, like so: <ComboBox IsEditable="True" Height="30"> <ComboBoxItem>robot</ComboBoxItem> <ComboBoxItem>Robot</ComboBoxItem> </ComboBox> If a user comes along and starts by typing a lower-case 'r' into that ComboBox when it is empty, the ComboBox predictably auto-fills itself with the word 'robot'. Great. Now the same user comes along and starts typing an upper-case 'R' into that ComboBox when it is again empty. Unpredictable, the ComboBox auto-fills itself with the lower-case word 'robot'. Not great. I desperately want it to auto-fill itself with 'Robot', but WPF does not seem to want to smile down upon me. No matter what you do (CAPS lock, shift+key), the ComboBox will always auto-fill with the lower case 'robot', provided that the lower case 'robot' precedes the upper case 'Robot' in the ComboBox's items collection. Is there any way to prevent this? This behavior is maddening and makes for an absolutely abysmal user experience.

  • In Zabbix how to separate data of the same type but from different sources?

    - by Jader Dias
    I have a machine that receives data from multiple sources. This machine forwards the data to the Zabbix Trapper. I want to be able to view this data separately. One way of doing that is to send data from each source with a different fake hostname. But this is not ideal. I can receive this data in more than one host. I would like to be able to see data from source 1 on host A separately from source 2 on host A and from source 1 in host B. Also posted on: http://www.zabbix.com/forum/showthread.php?t=16503

  • Transfer data between C++ classes efficiently

    - by David
    Hi, Need help... I have 3 classes, Manager which holds 2 pointers. One to class A another to class B . A does not know about B and vise versa. A does some calculations and at the end it puts 3 floats into the clipboard. Next, B pulls from clipboard the 3 floats, and does it's own calculations. This loop is managed by the Manager and repeats many times (iteration after iteration). My problem: Now class A produces a vector of floats which class B needs. This vector can have more than 1000 values and I don't want to use the clipboard to transfer it to B as it will become time consumer, even bottleneck, since this behavior repeats step by step. Simple solution is that B will know A (set a pointer to A). Other one is to transfer a pointer to the vector via Manager But I'm looking for something different, more object oriented that won't break the existent separation between A and B Any ideas ? Many thanks David

  • Display shift when adding rows to UITableView

    - by Kamchatka
    Hello, I have a UITableView displaying an underlying NSFetchedResultsController. When the fetchedResultsController is updated, - (void)controller:(NSFetchedResultsController *)controller didChangeObject:(id)anObject atIndexPath:(NSIndexPath *)indexPath forChangeType:(NSFetchedResultsChangeType)type newIndexPath:(NSIndexPath *)newIndexPath { is called. And the following is executed: case NSFetchedResultsChangeInsert: [tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:shiftedIndexPath] withRowAnimation:UITableViewRowAnimationFade]; break; The cellForRowAtIndexPath is only called for the new line (which is logical) The problem is however that all the values displayed in the rows of the table view are shifted down. The first row displays its title. The second rows displays the first row's title. The third row the second row's title etc. If I repeat that, the third row will display the second's row title, the fourth the third row's title etc. I don't understand what can happen, especially because cellForRowAtIndexPath is only called for the new line (which is logical) and not for all these lines. Additionally, if I click on these lines which have the wrong title, it opens the right document (didSelectRowAtIndexPath works correctly with the indexPath) Any clue of what could happen? Thanks!

  • LINQ DataLoadOptions - Retrieval of data via Fulltext/Broken Foreign Key Relationship

    - by Alex
    I've hit a brick wall: I have an SQL Function: FUNCTION [dbo].[ContactsFTS] (@searchtext nvarchar(4000)) RETURNS TABLE AS RETURN SELECT * FROM Contacts INNER JOIN CONTAINSTABLE(Contacts, *, @searchtext) AS KEY_TBL ON Contacts.Id = KEY_TBL.[KEY] which I am calling via LINQ public IQueryable<ContactsFTSResult> SearchByFullText(String searchText) { return db.ContactsFTS(searchText); } I am projecting the ContactsFTSResult collection into a List<Contact> which is then given to my viewmodel. Here is the problem: My Contacts table (and therefore the Contact object created via LINQ to SQL) has multiple FK relationships to other information, such as Contact.BillingAddressId is an FK to an Address.Id. That information is missing after I do the fulltext search (e.g. if I try to access Contact.BillingAddress it is null). Can I add this information somehow via DataLoadOptions? I tried LoadWith<Contact>(c => c.BillingAddress) but this doesn't work, I assume because of the fact that I'm calling the function instead of doing the whole query via LINQ.
