  • Query - Trying to SUM one field based on content of another field

    - by ShaneL
    Table: DayOfWeek Enrollments Monday 35 Monday 12 Saturday 25 Tuesday 15 Monday 9 Tuesday 15 Basically I'm trying to sum the total enrolments for each day. so the Output will look like: DayOfWeek Enrollments Monday 56 Saturday 25 Tuesday 30 I've spent around 4 hours trying to work this out trying many many different ways but no luck. The problem I'm having is i can count how many enrollments for each day but can't have it aligned with the correct day when i run the query e.g. I want The total to be on the same line as the day it was calculated from. (I hope that is clear enough)

  • Using LINQ to filter rows of a matrix based on inclusion in an array

    - by Bob Feng
    I have a matrix, IEnumerable<IEnumerable<int>> matrix, for example: { {10,23,16,20,2,4}, {22,13,1,33,21,11 }, {7,19,31,12,6,22}, ... } and another array: int[] arr={ 10, 23, 16, 20} I want to filter the matrix on the condition that I group all rows of the matrix which contain the same number of elements from arr. That is to say the first row in the matrix {10,23,16,20,2,4} has 4 numbers from arr, this array should be grouped with the rest of the rows with 4 numbers from arr. better to use linq, thank you very much!

  • Copy a value based on criteria Salesforce

    - by Robert
    Hi all, On a Salesforce.com opportunity I have a number of custom fields that are potential options that the end client will eventually select. Option 1 (Desc Field) Option 1 (Value) Option 2 (Desc Field) Option 2 (Value) Option 3 (Desc Field) Option 3 (Value) At a future point the user will ultimately choose one of the options as the preferred option. What I want is then the value for the chosen option to be stored in another field without the user having to enter it again. A “nice to have” would also be that all 3 option descriptions, values and selected value are locked once this is done. Any ideas?

  • Separating MySQL SELECT statement based on data in a column

    - by NightMICU
    Hi everyone, I need to retrieve data (vehicle details, in this case) from a MySQL table tabled and then loop through the results to generate separate lists for each category of vehicle. Is there a simple way to do this without having to have a SELECT statement for each type of vehicle? If I were just doing this for one category, I would use the following: <?php $sql = "SELECT * FROM apparatus WHERE vehicleType = 'Support'; $getSQL = mysql_query($sql); ?> <ul> <?php while ($vehicleData = mysql_fetch_assoc($getSQL)) {?> <li><?php echo $vehicleData['name'];?></li> <?php } ?> </ul> ..etc. Need to do this for four different types of vehicles. Thanks!

  • Rails - using :include to find objects based on their child's attributes

    - by adam
    I have a sentence and correction model class Sentence < ActiveRecord::Base has_one :correction class Correction < ActiveRecord::Base belongs_to :sentence and I'm trying find all sentences which don't have a correction. To do this I'm simply looking for corrections which don't exist i.e. whose id = nil. But it is failing and i can't figure out why Sentence.find :all, :include => :correction, :conditions => {:correction => {:id => nil}} Perhaps its the syntax or maybe just the overall approach. Can anyone help?

  • How to assign a numbering scheme to TreeNodes based on position

    - by TChristian
    I have a TreeView control in a Windows Forms application that is displaying my own subclass of TreeNode. I need to display a number along with each node's text indicating its position in the tree, like 1 for the root, 1.1 for its first child, 1.2 for its second child, etc. I'm using C# with .NET 2.0 The best that I can come up with is, after the tree is built, go to each node, recursively find the parent and append the parent's sibling number to the front of the node's text until you reach the root.

  • Call function based off of a string in Lisp

    - by powerj1984
    I am passing in command line arguments to my Lisp program and they are formatted like this when they hit my main function: ("1 1 1" "dot" "2 2 2") I have a dot function and would like to call it directly from the argument, but this isn't possible because something like (funcall (second args)...) receives "dot" and not dot as the function name. I tried variations of this function: (defun remove-quotes (s) (setf (aref s 0) '"")) to no avail, before realizing that the quotes were not really a part of the string. Is there a simple way to do this, or should I just check each string and then call the appropriate function? Thanks!

  • .htaccess authentication from a php script to prevent a browser dialog box

    - by digitalbart
    Using php I authenticate a user, then behind the scenes,they are then again authenticated a second time with a single .htaccess username & password. This would be the same for all users, but I would not want them to have to enter a username and password again and they would now be allowed to enter the password protected directory. I prefer not to use http://username@password:somedomain.com. Any thoughts?

  • Defining Views Based On Selection

    - by Wayne
    Well the title isn't very descriptive but I'm not exactly sure how to explain but here goes! I have a web application (can use either MVC or standard web forms) which a user signs in to. If the user has signed up for more than one product they will have the option to switch between them. For the sakes of this example lets say User1 signs in and has access to Product1, Product2 and Product3. Now, each product will be very different and offer different functionally. What I want is the main view to be focused around the product they have selected and not redirected to a sub domain. What I don't want to have to do is get them to go to www.mysite.com/product1 or www.mysite.com/product2 but simply www.mysite.com regardless of the product they have selected and have the site render the views etc for that product. Wow does any of that make any sense? I was thinking mabe the use of sessions or something and URL rewriting? Are there any sample apps out there that make use of the same kind of functionallity that I could take a look at? Thanks for any help I appreciate it!

  • Identifying when there is more than 1 in a group based on grouped field

    - by Brian Cascone
    Sorry for the bad description it is tough to explain in one sentence. I have a dataset that has Cause field (RootCause) and an ID field (GroupID). Both can be many things but I need to identify where a GroupID has a multiple different rootcauses. for example: RootCause GrpId AAA 111 BBB 222 CCC 111 I am looking to be able to identify that GrpId 111 has two different RootCauses. This is what I have so far: Select [RootCause], GrpId, Count(GrpID) as CntGrpId From DB.dbo.Table Where DatatypeField <> '' Group BY [RootCause],GrpId This results set visualy gives me enough information to identify what I am looking for, but i need something better. I am looking to return only the ones that have multiples. Any ideas? Thanks

  • Hotkey to preview in browser in second monitor while still keeping focus in editor?

    - by Tony_Henrich
    I use two monitors. The second one has a browser open. I use Visual studio in the first monitor and making edits to the web page. Would love to press a key and instantly see the change in the browser. Basically doing a refresh in the browser behind the scene and still keep window focus in the editor. Instead of keep switching to the browser, refresh, switch back to VS. Any better ideas than using a keyboard recorder like AutoPilot?

  • Are Triggers Based On Queries Atomic?

    - by David
    I have a table that has a Sequence number. This sequence number will change and referencing the auto number will not work. I fear that the values of the trigger will collide. If two transactions read at the same time. I have ran simulated tests on 3 connections @ ~1 million records each and no collisions. CREATE TABLE `aut` ( `au_id` int(10) NOT NULL AUTO_INCREMENT, `au_control` int(10) DEFAULT NULL, `au_name` varchar(50) DEFAULT NULL, `did` int(10) DEFAULT NULL, PRIMARY KEY (`au_id`), KEY `Did` (`did`) ) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=latin1 TRIGGER `binc_control` BEFORE INSERT ON `aut` FOR EACH ROW BEGIN SET NEW.AU_CONTROL = (SELECT COUNT(*)+1 FROM aut WHERE did = NEW.did); END;

  • Filtering NSMutableArray based on enum property

    - by Marty
    I've got an NSMutableArray filled with objects of type "GameObject". GameObject has a number of properties, one of which being "gameObjectType" . "gameObjectType" is of type GameObjectTypeEnum. I want to be able to filter this NSMutableArray so only GameObjects of a certain type are returned. I've got the following in place, but it's giving me a "BAD ACCESS" error: NSPredicate *predicate = [NSPredicate predicateWithFormat:@"gameObjectType = %@", gameObjectType]; return [gameObjects filteredArrayUsingPredicate:predicate]; Is it possible to pass a "custom" type (ie, this enum I've defined) into the predicateWithFormat call?

  • Exclude nodes based on attribute wildcard in XSL node selection

    - by C A
    Using cruisecontrol for continuous integration, I have some annoyances with Weblogic Ant tasks and how they think that server debug information are warnings rather than debug, so are shown in my build report emails. The XML output from cruise is similar to: <cruisecontrol> <build> <target name="compile-xxx"> <task name="xxx" /> </target> <target name="xxx.weblogic"> <task name="wldeploy"> <message priority="warn">Message which isn't really a warning"</message> </task> </target> </build> </cruisecontrol> In the cruisecontrol XSL template the current selection for the task list is: <xsl:variable name="tasklist" select="/cruisecontrol/build//target/task"/> What I would like is something which selects the tasklist in the same way, but doesn't include any target nodes which have the attribute name="*weblogic" where * is a wildcard. I have tried <xsl:variable name="tasklist" select="/cruisecontrol/build//target[@name!='*weblogic']/task"/> but this doesn't seem to have worked. I'm not an expert with XSLT, and just want to get this fixed so I can carry on the real development of the project. Any help is much appreciated.

The Problem i am facing is if this if this person starts forwarding his IP from a proxy server then i am unable to track authenticity of the data. How do i detect if the IP forwarding is happening/ get the real ip address of the person.
