  • Query useing two databases in SQL Report Builder

    - by user912447
    I am new to SQL Server Report Builder 2.0 and I need to compare two different databases in one query. Basically I need to check if values from one database table exist in a different database's table. I know I can add multiple Datasources to my report and access each one with Subreports, but each DataSet that I create can only have one query in it. So how can I go about using one query to access two databases? Or if there is another way to somehow join my results from multiple DataSets, that would work too. Also, the databases are on the same server.

  • Sum of distinc rows after a 1-many table join

    - by Lock
    I have 2 tables that I am joining. Table 1 has 1-many relationship with table 2. That is, table 2 can return multiple rows for a single row of table 1. Because of this, the records of table 1 is duplicated for as many rows as are on table 2.. which is expected. Now, I have a sum on one of the columns from table 1, but because of the multiple rows that get returned on the join, the sum is obviously multiplying. Is there a way to get this number back to its original number? I tried dividing by the count of rows from table 2 but this didnt quite give me the expected result. Are there any analytical functions that could do this? I almost want something like "if this row has not yet been counted in the sum, add it to the sum"

  • MySQL: Selecting One Record When Others Have Same Data

    - by LoganFrederick
    I have a table of cities that all share the same area code: 367 01451 Harvard Worcester Massachusetts MA 978 Eastern 368 01452 Hubbardston Worcester Massachusetts MA 978 Eastern 369 01453 Leominster Worcester Massachusetts MA 978 Eastern The table has multiple area codes, all with multiple cities. What I'd like to do is only select one city from each area code and delete any extra cities from duplicate area codes. What would be the best query to accomplish this? I believe: http://stackoverflow.com/questions/596629/mysql4-sql-for-selecting-one-or-zero-record Is coming close to what I need but didn't quite get what/how those answers were working. Note The "978" row is the "area_code" row, table name is "zip_code".

  • How can I animate between states in a programmatic skin? [FLEX]

    - by Lewis
    I have a button with the various states (up/over/down etc) that uses a skin file to render the display. I want to achieve animation between the states. For instance, between the change from 'up' to 'over' I want to fade in a color and a border. The way I am doing this at the moment is to use viewstates and animate between them using transitions and the mx:AnimateProperty. However, using this method I can only animate one property per viewstate. So only the border, or the color can be animated. Does anyone know how I can achieve multiple animations on multiple properties of a programmatic button skin? Thanks in advance! Note: I have looked into using tweener but cannot see how it would help my situation

  • Efficiency: what block size of kernel-mode memory allocations?

    - by Robert
    I need a big, driver-internal memory buffer with several tens of megabytes (non-paged, since accessed at dispatcher level). Since I think that allocating chunks of non-continuous memory will more likely succeed than allocating one single continuous memory block (especially when memory becomes fragmented) I want to implement that memory buffer as a linked list of memory blocks. What size should the blocks have to efficiently load the memory pages? (read: not to waste any page space) A multiple of 4096? (equally to the page size of the OS) A multiple of 4000? (not to waste another page for OS-internal memory allocation information) Another size? Target platform is Windows NT = 5.1 (XP and above) Target architectures are x86 and amd64 (not Itanium)

  • How to model localized items

    - by tweir
    I'm currently designing a e-commerce solution. One of the primary requirements is for the store to support localized item details. The same store must be able to support multiple languages via the user's language selection and/or browser preference. I have two tables: Item (id, sku, price, ...) ItemDetails (item_id, language, title, ...) For each Item, there will be multiple rows corresponding to the item, where the (item_id,language) pair will be unique. I would like to model this as: class Item { public string sku; public double price; public ItemDetails Details; } Based on the user's session, I would like the items returned to have the Details object corresponds to the user's selected language (from their session). What are some approaches for representing this?

  • Response Time is different for mulitiple execution of the application with the same request Performa

    - by sivananda
    My java application functionality is to provide reference data (basically loads lots of data from xml files into hashmap) and hence we request for one such data from the hashmap based on a id and we have such multiple has map for different set of business data. The problem is that when i tried executing the java application for the same request multiple times, the response times are different like 31ms, 48ms, 72ms, 120ms, 63ms etc. hence there is a considerable gap between the min and max time taken for the execution to complete. Ideally, i would expect the response times to be like, 63ms, 65ms, 61ms, 70ms, 61ms, but in my case the variation of the response time for the same request is varying hugely. I had used a opensource profile to understand if there is any extra execution of the methods or memory leak, but as per my understanding there was no problem. Please let me know what could be the reasons and how can i address this problem.

  • Azure Service Bus Scalability

    - by phebbar
    I am trying to understand how can I make Azure Service Bus Topic to be scaleable to handle 10,000 requests/second from more than 50 different clients. I found this article at Microsoft - http://msdn.microsoft.com/en-us/library/windowsazure/hh528527.aspx. This provides lot of good input to scale azure service bus like creating multiple message factories, sending and receiving asynchronously, doing batch send/receive. But all these input are from the publisher and subscriber client perspective. What if the node running the Topic can not handle the huge number of transactions? How do I monitor that? How do I have the Topic running on multiple nodes? Any input on that would be helpful. Also wondering if any one has done any capacity testing with Topic/Queue and I am eager to see those results... Thanks, Prasanna

  • URL Rewriting from a subdomain to main domain!

    - by JCHASE11
    Hello. I am developing a pretty large website for a client, and its about 90% complete. It is currently hosted on a subdomain like so: now: v2.websitehere.com when complete: www.websitehere.com My problem is that SO much of this site is linked to the temporary subdomain. The newsletter service, multiple google apis, etc. I also have multiple blogs installed that would be hard to move over. Literally, I have over 20 blogs hosted on the subdomain. I also have other PHP scripts that utilize SQL databases. So, what I am getting at is that a migration would be very difficult: time consuming, frustrating, and not something I want to do. I am looking for a a good solution...similar to Wordpress's URL rewriting. Is there something I can do with .htaccess file? Any ideas would be MUCH appreciated.

  • How to use ccache selectively?

    - by Anonymous
    I have to compile multiple versions of an app written in C++ and I think to use ccache for speeding up the process. ccache howtos have examples which suggest to create symlinks named gcc, g++ etc and make sure they appear in PATH before the original gcc binaries, so ccache is used instead. So far so good, but I'd like to use ccache only when compiling this particular app, not always. Of course, I can write a shell script that will try to create these symlinks every time I want to compile the app and will delete them when the app is compiled. But this looks like filesystem abuse to me. Are there better ways to use ccache selectively, not always? For compilation of a single source code file, I could just manually call ccache instead of gcc and be done, but I have to deal with a complex app that uses an automated build system for multiple source code files.

  • How to organize Windows Phone code base to target both 7.x and 8 platforms

    - by ljubomir
    I took over a Windows Phone project which was previously targeting WP 7.1 platform, and with the recent announcement of the new platform it should target WP 8 as well. My VS 2010 solution consists on several projects (Data access, Model, Tests and WP7 client app) and i am wandering on how to include support for WP8. I have to note that the code-base is not compatible with WP8, due to usage of Toolkit controls and other 3rd party libraries targeted for WP7.1 specifically. Also there is another problem with the Visual Studio versions - WP7.1 can work with VS 2010, but WP8 requires VS 2012. Should i move the whole code-base to VS 2012? Any good advice on how to organize code-base in a most meaningful way in order to avoid duplication and possible painful maintenance? I am thinking between one solution - multiple projects vs. multiple solutions - reusable projects approach. Code duplication (like two separate folders/solutions) should be the least possible approach (fallback).

  • Grouping and retrieving most recent entry in a table for each group

    - by Lisa
    First off, please bear with me if I don't state the SQL question correctly. I have a table that has multiple columns of data. The selection criteria for my table groups based on column 1(order #). There could be multiple items on each order, but the item #'s are not grouped together. Example: Order Customer Order Date Order Time Item Quantity 123456 45 01/02/2010 08:00 140 4 123456 45 01/02/2010 08:30 270 29 123456 45 03/03/2010 09:00 140 6 123456 45 04/02/2010 09:30 140 10 123456 45 04/02/2010 10:00 270 35 What I need is a result like: Order Customer Order Date Order Time Item Quantity 123456 45 04/02/2010 09:30 140 10 123456 45 04/02/2010 10:00 270 35 This result shows that after all the changes the final order includes 10 of Item 140 and 35 of Item 270. Is this possible. python

  • Android: Referring to a string resource when defining a log name

    - by spookypeanut
    In my Android app, I want to use a single variable for the log name in multiple files. At the moment, I'm specifying it separately in each file, e.g. public final String LOG_NAME = "LogName"; Log.d(LOG_NAME, "Logged output); I've tried this: public final String LOG_NAME = (String) getText(R.string.app_name_nospaces); And while this works in generally most of my files, Eclipse complains about one of them: The method getText(int) is undefined for the type DatabaseManager I've made sure I'm definitely importing android.content.Context in that file. If I tell it exactly where to find getText: Multiple markers at this line - Cannot make a static reference to the non-static method getText(int) from the type Context - The method getText(int) is undefined for the type DatabaseManager I'm sure I've committed a glaringly obvious n00b error, but I just can't see it! Thanks for all help: if any other code snippets would help, let me know.

  • Passing a multi-line string as an argument to a script in Windows

    - by Zack Mulgrew
    I have a simple python script like so: import sys lines = sys.argv[1] for line in lines.splitlines(): print line I want to call it from the command line (or a .bat file) but the first argument may (and probably will) be a string with multiple lines in it. How does one do this? Of course, this works: import sys lines = """This is a string It has multiple lines there are three total""" for line in lines.splitlines(): print line But I need to be able to process an argument line-by-line. EDIT: This is probably more of a Windows command-line problem than a Python problem. EDIT 2: Thanks for all of the good suggestions. It doesn't look like it's possible. I can't use another shell because I'm actually trying to invoke the script from another program which seems to use the Windows command-line behind the scenes.

  • Why can I check some event handlers for null, some not?

    - by Inno
    Hi, I have a ugly piece of code that adds event handlers. The problem is, if the code is called multiple times, the event handlers are called multiple times. To solve the problem, I remove the event handler first and then add it. Now I've seen the following behaviour: Some event handlers can be checked like: if (object.event == null) { // // Code // } others of the form if (object.object.event == null) { // // Code // } I get a message like 'object.object.event' may only occur left of -= or +=. (Since I'm using a german version of visual studio, I don't know the correct translation to english). I have no idea why the behaviour looks this inconsequent so I would be grateful for some information on this. To be more specific: It's user control. if (myControl.Event == null) { // // works // } if (myControl.TreeView.NodeMouseClick == null) { // // doesn't work // }

  • How to register a VB.Net User Control with jQuery

    - by BornReady
    Greetings and thank you in advance for the help. I created a user control in VB.NET that uses a jQuery datepicker. I am at an impasse. The code I have works for one datepicker control on the page but because I can only register the client script once, it will not work for multiple instances/datepickers on the same page. What is the best way to go about initiating the jQuery script for this control so I can use it multiple times on one page? Can I append to ClientScript.RegisterStartupScript? Thanks again.

  • MVC Model architecture

    - by ATT
    I'm getting into CodeIgniter and trying to figure out the good architecture for my models. What kind of models would you create for the following simple example: list page of blog entries: shows part of the entry data, number of comments blog entry page: shows all the entry data, comment list (with part of the comment data) comment page: shows all the comment data I'm trying to get this right so that it's simple and effective. I don't want to load too much information (from the db) on the pages where I don't need them. E.g. should the same entry model handle both multiple entries as well as a single entry? And how should the comments be loaded? I only need the number of comments on the multiple entries (list) page but some of the comment data on the single entry page. How would you handle this?
