  • Basic SQL query question

    - by user318573
    Hello, I have the following query: SELECT Base.ReportDate, Base.PropertyCode, Base.FirstName, Base.MiddleName, Base.LastName, Person.FirstName, Person.MiddleName, Person.LastName FROM LeaseT INNER JOIN Base ON LeaseT.LeaseID = Base.LeaseID INNER JOIN Person ON LeaseT.TenantID = Person.ID works fine, except there could be 0 to 'N' people in the 'Person' table for each record in the Base table, but I only want to return exactly 1 for each 'Base' record (doesn't matter which, but the one with the lowest Person.ID) would be a reasonable choice. If there is 0 rows in the person table, I still need to return the row, but with null values for the 'person' fields. How would I structure the SQL to do that? Thanks. Edit: Yes, the tables are probably not structured properly, but restructuring at this time is not possible - got to work with what is there.

  • Basic LaTeX questions

    - by bpc89
    Two (hopefully quick) questions about LaTeX: How do you number select functions? I'm working in a documentclass{article}, if that matters. I want to have certain functions numbered such as function1 function2 (1) function3 function4 (2) How do you make a sign to evaluate an integral? I know how to do brackets, but is it possible to only make one straight light to the right of the function with the bounds of integration? I can't figure out how to do that.

  • Win2k3 password Authentication using LDAP in VC++

    - by user001
    Hi, I need to implement the Win2k3 password validation policy. As my application resides on Win2k3 cane we validate the password directly with windows domain password by using LDAP. This is because application design does not want to store 8/more password entry into DB and validate new password against that. As Windows already does same thing and using LDAP we can lookup into windows server. Can any one please let me know LDAP API to fulfill above requirement in VC++.

  • MVC4 not binding a list of basic types

    - by admanb
    I cannot, for the life of me, get this data to bind. Here's my JavaScript: var params = { 'InvItemIDs': ["188475", "188490"]}; $.post("api/Orders/OrderFromInventory?" + $.param(params)) and the Controller action: public HttpResponseMessage OrderFromInventory(IList<int> InvItemIDs) { return new HttpResponseMessage(); } I've built the query string so that it's sending: ?InvItemIDs=188475&InvItemIDs=188490 as well as ?InvItemIDs[]=188475&InvItemIDs[]=188490 and even ?InvItemIDs[0]=188475&InvItemIDs[1]=188490 and none of them are binding. InvItemIDs is always null. What am I doing wrong? EDIT: So it turns out all this is a bug (or something) in the new Web API controller code in MVC4. As soon as I moved the exact same code over to a standard controller it started working. I'm still interested if anyone has any insight as to why the Web API would break this binding.

  • MS Excel 03 - Deleting rows that have live string identifiers in column A, while concatenating other

    - by Justin
    I have this xml document that is provided as a data feed (right off the bat I can not modify the source of the data feed) and i import it into excel with the xml import. there is no schema that comes with this xml so i get a table that ends up having a whole bunch of duplicates for an identifier, because of the unique values spread throughout the spreadsheet. XML in XLS Col1(IDnum) Col2(name) Col3(Type) Col4(Category) Col(etc) ================================================================= 0011 Item 01 6B 0011 Item xxj9 7B 0011 Item xxj9 0011 Item 02 0011 Item 01 xxj9 6B 0012 etc I need to delete all rows where columnA string/number matches while concatenating all potential values from Col3, Col4 & Col5 together so it looks like this Col1(IDnum) Col2(name) Col3(Type) Col4(Category) Col(etc) ================================================================= 0011 Item 01, 02 xxj9 6B, 7B what visual basic method would allow me to accomplish this? thanks

  • Using jQuery, how do I way attach a string array as a http parameter to a http request?

    - by predhme
    I have a spring controller with a request mapping as follows @RequestMapping("/downloadSelected") public void downloadSelected(@RequestParam String[] ids) { // retrieve the file and write it to the http response outputstream } I have an html table of objects which for every row has a checkbox with the id of the object as the value. When they submit, I have a jQuery callback to serialize all ids. I want to stick those ids into an http request parameter called, "ids" so that I can grab them easily. I figured I could do the following var ids = $("#downloadall").serializeArray(); Then I would need to take each of the ids and add them to a request param called ids. But is there a "standard" way to do this? Like using jQuery?

  • Basic question about encryption - what exactly are keys?

    - by Tomas
    Hi, I was browsing and found good articles about encryption. However, none of them described why the key lenght is important and what exactly the key is used for. My guess is that could work this way: 0101001101010101010 Key: 01010010101010010101 //the longer the key, the longer unique sequence XOR or smth: //result Is this at least a bit how it works or I am missing something? Thanks

  • Password protected web content-- basic question

    - by nickpish
    I'm looking to create a password-protected section of my website that requires user login, and I'm wondering what approach would provide the simplest solution. For the most part, the site will be very simple and static-- i.e. no real requirement for a database/backend-- with the protected content contained in a single directory, which I've already configured on my server via htaccess. I guess I'm wondering ultimately if it's possible to use a script of some sort that will enable access to this protected directory via a form and thereby bypass the need for configuring a mySQL/PHP solution? Furthermore, this protected content is not exactly hyper-sensitive, but private nonetheless. Thanks much for any direction here.

  • how can I reliably check that requests to my service file have come from my website?

    - by woot586
    I have a service.php class that I use to service AJAX calls from my website. To prevent other people accessing the service using PHP CURL I would normally check the request has come from mysite, and if they are not then just redirect to my home page e.g. if($_SERVER['HTTP_REFERER'] != "http://www.mysite.com"){ header('location: http://www.mysite.com'); exit; } I read in the PHP holy bible: http://www.php.net/manual/en/reserved.variables.server.php that "Not all user agents will set this, and some provide the ability to modify HTTP_REFERER as a feature. In short, it cannot really be trusted." So if this method is not reliable, my question is how can I reliably check that requests to my service file have come from my website? Thanks for any help you can provide!

  • Visual Basic Display Square

    - by user1724157
    Alright I'm currently lost on a particular assignment I have for a class. I've seen many examples of this app but none of them see to help my problem is as follows: Write a Sub procedure "DisplaySquare" to display the solid square. The size should be specified by the integer parameter "size". The character that fills the square should be specified by the string parameter "fillCharacter. Use a For...Next statement nested within another For...Next statement to create the square. The outer For...Next specifies what row is currently being displayed. The inner For...Next appends all the characters that form the row to a display string. So it should come out like as follows: if a user enters "8" and "#" ######## ######## ######## ######## ######## ######## ######## ######## Any help would be appreciated.

  • Basic visual studio intellisense question

    - by maxp
    Ive used visual studio for years, but the answer this eludes me: When intellisense pops up, for a method call that takes more than one parameter, the summary for the first parameter is shown. The only way i've found to show the summary for the following parameter(s) is to either supply each parameter or just hit comma until i get the one im looking for. Ive tried ctrl+right arrow, shift + right arrow etc etc, without success. Just curious is all.

  • C++ Basic Class Layout

    - by Spencer
    Learning C++ and see the class laid out like this: class CRectangle { int x, y; public: void set_values (int,int); int area () {return (x*y);} }; void CRectangle::set_values (int a, int b) { x = a; y = b; } I know Java and methods(functions) in Java are written within the class. The class looks like a Java interface. I know I can write the class like this: class CRectangle { int x, y; public: void set_values (int a, int b) { x = a; y = b; }; int area () {return (x*y);} }; But is there a difference or standard?
