  • Highly efficient filesystem APIs for certain kinds of operations

    - by romkyns
    I occasionally find myself needing certain filesystem APIs which could be implemented very efficiently if supported by the filesystem, but I've never heard of them. For example: Truncate file from the beginning, on an allocation unit boundary Split file into two on an allocation unit boundary Insert or remove a chunk from the middle of the file, again, on an allocation unit boundary The only way that I know of to do things like these is to rewrite the data into a new file. This has the benefit that the allocation unit is no longer relevant, but is extremely slow in comparison to some low-level filesystem magic. I understand that the alignment requirements mean that the methods aren't always applicable, but I think they can still be useful. For example, a file archiver may be able to trim down the archive very efficiently after the user deletes a file from the archive, even if that leaves a small amount of garbage either side for alignment reasons. Is it really the case that such APIs don't exist, or am I simply not aware of them? I am mostly interested in NTFS, but hearing about other filesystems will be interesting too.

  • How to get number of elements of a class before a certain element

    - by David Shaikh
    I want to know how many elements of a certain class appear in the DOM before an element that let's say has been clicked on. <html> <div class="a"> </div> <div class="b"> <div class="a"> </div> </div> <button>CLick me!</button> <div class="a"> </div> </html> So in the previous DOM tree if the element to be clicked is the button, and Im looking for divs with class "a" it should return 2, even though in the whole tree there are 3, but "before" the button there are only 2. How could I do that? Thanks

  • How to make a service not receive messages at certain times

    - by miker169
    I'm currently learning wcf for an up and coming project. The service I am creating is using MSMQ to update the database, but the database can't accept messages at certain times. The service is going to be a windows service. The one thing I am coming up against at the moment is how I can get the service to stop reading messages from the queue at these times, for instance lets say I don't want to read messages from the queue on sundays. How would I go about implementing this. So that the client can send messages to the queue that update the database but the service doesn't read the messages until monday, so that the database gets all the updates on the monday? I have started looking at creating a customhost, but I'm not sure if I'm heading in the right direction with this. Thanks in advance.

  • Replace the content of a tag with a certain class

    - by fire
    I am looking for suitable replacement code that allows me replace the content inside of any HTML tag that has a certain class e.g. $class = "blah"; $content = "new content"; $html = '<div class="blah">hello world</div>'; // code to replace, $html now looks like: // <div class="blah">new content</div> Bare in mind that: It wont necessarily be a div, it could be <h2 class="blah"> The class can have more than one class and still needs to be replaced e.g. <div class="foo blah green">hello world</div> I am thinking regular expressions should be able to do this, if not I am open to other suggestions such as using the DOM class (although I would rather avoid this if possible because it has to be PHP4 compatible).

  • Trying to exclude certain extensions doing a recursive copy (MSBuild)

    - by Kragen
    I'm trying to use MSBuild to read in a list of files from a text file, and then perform a recursive copy, copying the contents of those directories files to some staging area, while excluding certain extensions (e.g. .tmp files) I've managed to do most of the above quite easily using CreateItem and the MSBuild copy task, whatever I do the CreateItem task just ignores my Exclude parameter: <PropertyGroup> <RootFolder>c:\temp</RootFolder> <ExcludeFilter>*.tmp</ExcludeFilter> <StagingDirectory>staging</StagingDirectory> </PropertyGroup> <ItemGroup> <InputFile Include="MyFile.txt" /> </ItemGroup> <Target Name="Build"> <ReadLinesFromFile File="@(InputFile)"> <Output ItemName="AllFolders" TaskParameter="Lines" /> </ReadLinesFromFile> <CreateItem Include="$(RootFolder)\%(AllFolders.RelativeDir)**" Exclude="$(ExcludeFilter)"> <Output ItemName="AllFiles" TaskParameter="Include" /> </CreateItem> <Copy SourceFiles="@(AllFiles)" DestinationFolder="$(StagingDirectory)\%(RecursiveDir)" Example contents of 'MyFile.txt': somedirectory\ someotherdirectory\ (I.e. the paths are relative to $(RootFolder) - mention this because I read somewhere that it might be relevant) I've tried loads of different combinations of Exclude filters, but I never seem to be able to get it to correctly exclude my .tmp files - is there any way of doing this with MSBuild without resorting to xcopy?

  • Copy Selective Data from Database to Invoice, Based on Certain Criteria

    - by Scott
    For starters, here is an example of a microsoft excel database I am working with: Month/Address/Name/Description/Amount January/123 Street/Fred/Painting/100 January/456 Avenue/Scott/Flooring/400 January/789 Road/Scott/Plumbing/100 February/123 Street/Fred/Flooring/600 February/246 Lane/Fred/Electrical/300 March/789 Road/Scott/Drywall/150 What I want to be able to do is selectively copy info from this databse to invoices (also excel). The invoice has three columns: Address/Description/Amount. I want to be able to automatically fill the invoices in as the database is filled in (either automatically, or if I have to actually manually run the macro to do it, that might be fine). Each name (Scott, Fred, etc.) will have their own set of 12 invoices for the year. So, e.g., I want to be able to produce a January invoice for all work done for Scott in January, showing the address, the description and the amount, line by line. So every time work on Scott's address(es) is done, the database is filled in, and i want it to "send" that information to the invoice on the next available line, filling in only the Address/Description/Amount columns from the database. Fred's invoice should fill in as any work is done on Fred's addresses. And once the month changes, the next invoice should start filling in. So first I need to filter the data by the month and the name (and there is actually one more column to filter by, but let's keep this example simpler). Then I need to list the remaining data on the invoice, but only certain cells from the rows that are now left. Help anyone?

  • Force full garbage collection when memory occupation goes beyond a certain threshold

    - by Silvio Donnini
    I have a server application that, in rare occasions, can allocate large chunks of memory. It's not a memory leak, as these chunks can be claimed back by the garbage collector by executing a full garbage collection. Normal garbage collection frees amounts of memory that are too small: it is not adequate in this context. The garbage collector executes these full GCs when it deems appropriate, namely when the memory footprint of the application nears the allotted maximum specified with -Xmx. That would be ok, if it wasn't for the fact that these problematic memory allocations come in bursts, and can cause OutOfMemoryErrors due to the fact that the jvm is not able to perform a GC quickly enough to free the required memory. If I manually call System.gc() beforehand, I can prevent this situation. Anyway, I'd prefer not having to monitor my jvm's memory allocation myself (or insert memory management into my application's logic); it would be nice if there was a way to run the virtual machine with a memory threshold, over which full GCs would be executed automatically, in order to release very early the memory I'm going to need. Long story short: I need a way (a command line option?) to configure the jvm in order to release early a good amount of memory (i.e. perform a full GC) when memory occupation reaches a certain threshold, I don't care if this slows my application down every once in a while. All I've found till now are ways to modify the size of the generations, but that's not what I need (at least not directly). I'd appreciate your suggestions, Silvio P.S. I'm working on a way to avoid large allocations, but it could require a long time and meanwhile my app needs a little stability

  • Display object in just a certain viewport

    - by PSilo
    Hi I got 4 viewports and one large that I can switch between now I got an object namely the camera and the cameras target position that I show with rendering a sphere at those locations. I want to show the cameras position in 3 of my viewports but not in the last which is the camera display but at the moment I got an all or nothing scenario. void display(int what) { if(what==5){ glMatrixMode(GL_MODELVIEW); glLoadIdentity(); camControll();} if(what==1){ glMatrixMode(GL_MODELVIEW); glLoadIdentity(); gluLookAt(75,15,-5,0,5,-5,0,1,0);} if(what==2){ glMatrixMode(GL_MODELVIEW); glLoadIdentity(); gluLookAt(0,110,0,0,0,0,1,0,0);} if(what==3){ glMatrixMode(GL_PROJECTION); glLoadIdentity(); gluPerspective(45.0f, float(320) / float(240), 0.1f, 100.0f); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); camControll();} if(what==4){ glMatrixMode(GL_MODELVIEW); glLoadIdentity(); gluLookAt(185,75,25,0,28,0,0,1,0);} //glMatrixMode(GL_MODELVIEW); //glLoadIdentity(); ////gluLookAt(cos(shared.time) * shared.distance, 10, sin(shared.time) * shared.distance, 0, 0, 0, 0, 1, 0); ////ca.orbitYaw(0.05); //ca.lookAt(); glClearColor(0, 0, 0, 1); glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT); drawScene(); // scene that all views should render drawCamera(); / camera position that only certain views should render glutSwapBuffers(); } I'm thinking that perhaps I could do one sweep for first the 3 viewports and then call glutSwapBuffers() and then do the other viewport without the camera position but some stuttering I previously had was traced to glutSwapBuffers() being called for each viewport so I guess there has to be another way only that I cant figure it out.

  • XSLT fails to load huge XML doc after matching certain elements

    - by krisvandenbergh
    I'm trying to match certain elements using XSLT. My input document is very large and the source XML fails to load after processing the following code (consider especially the first line). <xsl:template match="XMI/XMI.content/Model_Management.Model/Foundation.Core.Namespace.ownedElement/Model_Management.Package/Foundation.Core.Namespace.ownedElement"> <rdf:RDF> <rdf:Description rdf:about=""> <xsl:for-each select="Foundation.Core.Class"> <xsl:for-each select="Foundation.Core.ModelElement.name"> <owl:Class rdf:ID="@Foundation.Core.ModelElement.name" /> </xsl:for-each> </xsl:for-each> </rdf:Description> </rdf:RDF> </xsl:template> Apparently the XSLT fails to load after "Model_Management.Model". The PHP code is as follows: if ($xml->loadXML($source_xml) == false) { die('Failed to load source XML: ' . $http_file); } It then fails to perform loadXML and immediately dies. I think there are two options now. 1) I should set a maximum executing time. Frankly, I don't know how that I do this for the built-in PHP 5 XSLT processor. 2) Think about another way to match. What would be the best way to deal with this? The input document can be found at http://krisvandenbergh.be/uml_pricing.xml Any help would be appreciated! Thanks.

  • Getting elements children with certain tag jQuery

    - by johnnyArt
    I'm trying to get all the input elements from a certain form from jQuery by providing only the name of the form and only knowing that those wanted fields are input elements. Let's say: <form action='#' id='formId'> <input id='name' /> <input id='surname'/> </form> How do I access them individually with jQuery? I tried something like $('#formId > input') with no success, in fact an error came back on the console "XML filter is applied to non-XML value (function (a, b) {return new (c.fn.init)(a, b);})" Maybe I have to do it with .children or something like that? I'm pretty new at jQuery and I'm not really liking the Docs. It was much friendlier in Mootools, or maybe I just need to get used to it. Oh and last but not least, I've seen it asked before but no final answer, can I create a new dom element with jQuery and work with it before inserting it (if I ever do) into de code? In mootools, we had something like var myEl = new Element(element[, properties]); and you could then refer to it in further expressions, but I fail to understand how to do that on jQuery Thanks in advance.

  • WordPress plugin to output a certain category on content page tweak help

    - by talkingD0G
    I'm using WordPress plugin Category Page to display the most recent 5 posts from a certain category on a regular content page (not the blog page) of a website. Right now the plugin is limited to display the post title linked to the post page. This is a video blog type site and I need the plugin to display the post title (as it does now) with the video as well. Probably just telling the script to show the content would work but I don't know how to tweak it. This is the section of the script that is outputting the post title: function page2cat_content_catlist($content){ global $post; if ( stristr( $content, '[catlist' )) { $search = "@(?:<p>)*\s*\[catlist\s*=\s*(\w+|^\+)\]\s*(?:</p>)*@i"; if (preg_match_all($search, $content, $matches)) { if (is_array($matches)) { $title = get_option('p2c_catlist_title'); if($title != "") $output = "<h4>".$title."</h4>"; else $output = ""; $output .= "<ul class='p2c_catlist'>"; $limit = get_option('p2c_catlist_limit'); foreach ($matches[1] as $key =>$v0) { $catposts = get_posts('category='.$v0."&numberposts=".$limit); foreach($catposts as $single): $output .= "<li><a href='".get_permalink($single->ID)." '>".$single->post_title."</a></li>"; endforeach; $search = $matches[0][$key]; $replace= $output; $content= str_replace ($search, $replace, $content); } $output .= "</ul>"; } } } return $content; } If anyone has any advice or knows how to help thanks in advance!

  • Socket isn't listed by netstat unless using certain ports

    - by illuzive
    I'm a computer science student with a few years of programming experience. Yesterday, while working on a project (Mac OS X, BSD sockets) at school, I encountered a strange problem. I was adding several modules to a very basic "server" (mostly a bunch of functions to set up and manage an UDP socket on a certain port). While doing this, I started the server from time to time in order to see that everything worked like it should. I've been using port 32000 during the development of the server. When I start the server and run netstat, the socket is listed as expected. > netstat -p UDP | grep 32000 udp46 0 0 *.32000 *.* However, when I run the server on other ports (random (10000 - 50000)), it's not listed by netstat. My thought was that I had somehow hard coded the port somewhere in the code, but that's not the case. The thing is - I can connect to the socket on any of the tested ports, and it reads data sent to it without any problem at all. It just doesn't get listed by netstat. What I wonder, is if anyone of you have any idea of why this happens? Note: Although this is a project at school, it's not homework. This is just something I want to understand for my own benefit.

  • Unable to use certain Fonts programatically in ASP.Net

    - by TooFat
    I am trying to programatically create a bitmap with a specified font in ASP.Net. The idea is that the text, font name, size color etc. will be passed in from variables and a bitmap of the text using the font etc will be returned. However, I have been finding that I am only able to do so using the following code with certain fonts. <div> <% string fontName = "Segoe Script"; //Change Font here System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(100, 100); System.Drawing.Graphics graph = System.Drawing.Graphics.FromImage(bmp); System.Drawing.Font fnt = new System.Drawing.Font(fontName, 20); System.Drawing.SolidBrush brush = new System.Drawing.SolidBrush(System.Drawing.Color.Red); graph.DrawString("Help", fnt, brush, new System.Drawing.Point(10, 10)); bmp.Save(@"C:\Development\Path\image1.bmp"); this.Image1.ImageUrl = "http://mysite/Images/image1.bmp"; %> <asp:Label ID="Label1" runat="server" Text="Label" Font-Names="Segoe Script"> <%Response.Write("Help"); %></asp:Label> //Change font here <asp:Image ID="Image1" runat="server" /> </div> If I change the font name in the areas indicated by the comments to Arial or Verdana both the image and the label appear with the correct font. If however, I change the font name in both locations to something "Segoe Script" the Label will show up in Segoe Script but the image is in what looks like Arial.

  • PHP & WP: Render Certain Markup Based on True False Condition

    - by rob
    So, I'm working on a site where on the top of certain pages I'd like to display a static graphic and on some pages I would like to display an scrolling banner. So far I set up the condition as follows: <?php $regBanner = true; $regBannerURL = get_bloginfo('stylesheet_directory'); //grabbing WP site URL ?> and in my markup: <div id="banner"> <?php if ($regBanner) { echo "<img src='" . $regBannerURL . "/style/images/main_site/home_page/mock_banner.jpg' />"; } else { echo 'Slider!'; } ?> </div><!-- end banner --> In my else statement, where I'm echoing 'Slider!' I would like to output the markup for my slider: <div id="slider"> <img src="<?php bloginfo('stylesheet_directory') ?>/style/images/main_site/banners/services_banners/1.jpg" alt="" /> <img src="<?php bloginfo('stylesheet_directory') ?>/style/images/main_site/banners/services_banners/2.jpg" alt="" /> <img src="<?php bloginfo('stylesheet_directory') ?>/style/images/main_site/banners/services_banners/3.jpg" alt="" /> ............. </div> My question is how can I throw the div and all those images into my else echo statement? I'm having trouble escaping the quotes and my slider markup isn't rendering.

  • JQuery click anywhere except certain divs and issues with dynamically added html

    - by jCuga
    I want this webpage to highlight certain elements when you click on one of them, but if you click anywhere else on the page, then all of these elements should no longer be highlighted. I accomplished this task by the following, and it works just fine except for one thing (described below): $(document).click(function() { // Do stuff when clicking anywhere but on elements of class suggestion_box $(".suggestion_box").css('background-color', '#FFFFFF'); }); $(".suggestion_box").click(function() { // means you clicked on an object belonging to class suggestion_box return false; }); // the code for handling onclicks for each element function clickSuggestion() { // remove all highlighting $(".suggestion_box").css('background-color', '#FFFFFF'); // then highlight only a specific item $("div[name=" + arguments[0] + "]").css('background-color', '#CCFFCC'); } This way of enforcing the highlighting of elements works fine until I add more html to the page without having a new page load. This is done by .append() and .prepend() What I suspected from debugging was that the page is not "aware" of the new elements that were added to the page dynamically. Despite the new, dynamically added elements having the appropriate class names/IDs/names/onclicks ect, they never get highlighted like the rest of the elements (which continue to work fine the entire time). I was wondering if a possible reason for why my approach does not work for the dynamically added content is that the page is not able to recognize the elements that were not present during the pageload. And if this is a possibility, then is there a way to reconcile this without a pageload? If this line of reasoning is wrong, then the code I have above is probably not enough to show what's wrong with my webpage. But I'm really just interested in whether or not this line of thought is a possibility.

  • Time taken for memcpy decreases after certain point

    - by tss
    I ve a code which increases the size of the memory(identified by a pointer) exponentially. Instead of realloc, I use malloc followed by memcpy.. Something like this.. int size=5,newsize; int *c = malloc(size*sizeof(int)); int *temp; while(1) { newsize=2*size; //begin time temp=malloc(newsize*sizeof(int)); memcpy(temp,c,size*sizeof(int)); //end time //print time in mili seconds c=temp; size=newsize; } Thus the number of bytes getting copied is increasing exponentially. The time required for this task also increases almost linearly with the increase in size. However after certain point, the time taken abruptly reduces to a very small value and then remains constant. I recorded time for similar code, copyin data(Of my own type) 5 -> 10 - 2 ms 10 -> 20 - 2 ms . . 2560 -> 5120 - 5 ms . . 20480 -> 40960 - 30 ms 40960 -> 91920 - 58 ms 367680 -> 735360 - 2 ms 735360 -> 1470720 - 2 ms 1470720 -> 2941440 - 2 ms What is the reason for this drop in time ? Does a more optimal memcpy method get called when the size is large ?

  • Replacing certain words with links to definitions using Javascript

    - by adharris
    I am trying to create a glossary system which will get a list of common words and their definitions via ajax, then replace any occurrence of that word in certain elements (those with the useGlossary class) with a link to the full definition and provide a short definition on mouse hover. The way I am doing it works, but for large pages it takes 30-40 seconds, during which the page hangs. I would like to either decrease the time it takes to do the replacement or make it so that the replacement is running in the background without hanging the page. I am using jquery for most of the javascript, and Qtip for the mouse hover. Here is my existing slow code: $(document).ready(function () { $.get("fetchGlossary.cfm", null, glossCallback, "json"); }); function glossCallback(data) { $(".useGlossary").each(function() { var $this = $(this); for (var i in data) { $this.html($this.html().replace(new RegExp("\\b" + data[i].term + "\\b", "gi"), function(m) {return makeLink(m, data[i].def);})); } $this.find("a.glossary").qtip({ style: { name: 'blue', tip: true } }) }); } function makeLink(m, def) { return "<a class='glossary glossary" + m.replace(/\s/gi, "").toUpperCase() + "' href='reference/glossary.cfm' title='" + def + "'>" + m + "</a>"; } Thanks for any feedback/suggestions!

  • How to skip certain tests with Test::Unit

    - by Daniel Abrahamsson
    In one of my projects I need to collaborate with several backend systems. Some of them somewhat lacks in documentation, and partly therefore I have some test code that interact with some test servers just to see everything works as expected. However, accessing these servers is quite slow, and therefore I do not want to run these tests every time I run my test suite. My question is how to deal with a situation where you want to skip certain tests. Currently I use an environment variable 'BACKEND_TEST' and a conditional statement which checks if the variable is set for each test I would like to skip. But sometimes I would like to skip all tests in a test file without having to add an extra row to the beginning of each test. The tests which have to interact with the test servers are not many, as I use flexmock in other situations. However, you can't mock yourself away from reality. As you can see from this question's title, I'm using Test::Unit. Additionally, if it makes any difference, the project is a Rails project.

  • Create an index only on certain rows in mysql

    - by dhruvbird
    So, I have this funny requirement of creating an index on a table only on a certain set of rows. This is what my table looks like: USER: userid, friendid, created, blah0, blah1, ..., blahN Now, I'd like to create an index on: (userid, friendid, created) but only on those rows where userid = friendid. The reason being that this index is only going to be used to satisfy queries where the WHERE clause contains "userid = friendid". There will be many rows where this is NOT the case, and I really don't want to waste all that extra space on the index. Another option would be to create a table (query table) which is populated on insert/update of this table and create a trigger to do so, but again I am guessing an index on that table would mean that the data would be stored twice. How does mysql store Primary Keys? I mean is the table ordered on the Primary Key or is it ordered by insert order and the PK is like a normal unique index? I checked up on clustered indexes (http://dev.mysql.com/doc/refman/5.0/en/innodb-index-types.html), but it seems only InnoDB supports them. I am using MyISAM (I mention this because then I could have created a clustered index on these 3 fields in the query table). I am basically looking for something like this: ALTER TABLE USERS ADD INDEX (userid, friendid, created) WHERE userid=friendid

  • Loop through multi-dimensional array and remove certain keys

    - by Webkungen
    Hi! I've got a nested tree structure which is based on the array below: Array ( [1] = Array ( [id] = 1 [parent] = 0 [name] = Startpage [uri] = 125 [basename] = index.php [child] = ) [23] = Array ( [id] = 23 [parent] = 0 [name] = Events [uri] = 0 [basename] = [child] = Array ( [24] = Array ( [id] = 24 [parent] = 23 [name] = Public news [uri] = 0 [basename] = [child] = Array ( [27] = Array ( [id] = 27 [parent] = 24 [name] = Add [uri] = 100 [basename] = news.public.add.php [child] = ) [28] = Array ( [id] = 28 [parent] = 24 [name] = Overview [uri] = 101 [basename] = news.public.overview.php [child] = ) ) ) [25] = Array ( [id] = 25 [parent] = 23 [name] = Private news [uri] = 0 [basename] = [child] = Array ( [29] = Array ( [id] = 29 [parent] = 25 [name] = Add [uri] = 67 [basename] = news.private.add.php [child] = ) [30] = Array ( [id] = 30 [parent] = 25 [name] = Overview [uri] = 68 [basename] = news.private.overview.php [child] = ) ) ) [26] = Array ( [id] = 26 [parent] = 23 [name] = Calendar [uri] = 0 [basename] = [child] = Array ( [31] = Array ( [id] = 31 [parent] = 26 [name] = Add [uri] = 69 [basename] = news.event.add.php [child] = ) [32] = Array ( [id] = 32 [parent] = 26 [name] = Overview [uri] = 70 [basename] = news.event.overview.php [child] = ) ) ) ) ) ) I'm looking for a function to loop (recursive?) through the array and remove some keys. I my system I can allow users to certain functions/pages and if I deny access to the whole "block" "Events", the array will look like this: Array ( [1] = Array ( [id] = 1 [parent] = 0 [name] = Startpage [uri] = 125 [basename] = index.php [child] = ) [23] = Array ( [id] = 23 [parent] = 0 [name] = Events [uri] = 0 [basename] = [child] = Array ( [24] = Array ( [id] = 24 [parent] = 23 [name] = Public news [uri] = 0 [basename] = [child] = ) [25] = Array ( [id] = 25 [parent] = 23 [name] = Private news [uri] = 0 [basename] = [child] = ) [26] = Array ( [id] = 26 [parent] = 23 [name] = Calendar [uri] = 0 [basename] = [child] = ) ) ) ) As you can see above, the whole "block" "Events" is useless right now, becuase there is no page associated with each option. So I need to find all "keys" where "basename" is null AND where child is not an array or where the array is empty and remove them. I found this function when searching the site: function searchAndDestroy(&$a, $key, $val){ foreach($a as $k = &$v){ if(is_array($v)){ $r = searchAndDestroy($v, $key, $val); if($r){ unset($a[$k]); } }elseif($key == $k && $val == $v){ return true; } } return false; } It can be used to remove a key any where in the array, but only based in one thing, for example remove all keys where "parent" equals "23". But I need to find and remove (unset) all keys where "basename" is null AND where child isn't an array or where the array is empty. Can anyone help me out and possibly tweak the function above? Thank you,

  • Use a certain select statement in a stored procedure depending on the Exec statement

    - by MyHeadHurts
    Alright so i am not even sure if this is possible I have a q_00 and q_01 and q_02 which are all in my stored procedure. then on the bottom i have 3 select statements that select a certain catagory for example Sales,Net Sales and INS sales What i want to be able to do is if the user types exec (name of my sp) (sales) (and a year which is the @yearparameter) it will run the sales select statement If they type Exec (name of my SP) netsales (@Yeartoget) it will show the net sales is this possible or do i need multiple stored procedures ALTER PROCEDURE [dbo].[casof] @YearToGet int as ; with q_00 as ( select DIVISION , SDESCR , DYYYY , sum(APRICE) as asofSales , sum(PARTY) as asofPAX , sum(NetAmount) as asofNetSales , sum(InsAmount) as asofInsSales , sum(CancelRevenue) as asofCXSales , sum(OtherAmount) as asofOtherSales , sum(CXVALUE) as asofCXValue from dbo.B101BookingsDetails where Booked <= CONVERT(int,DateAdd(year, @YearToGet - Year(getdate()), DateAdd(day, DateDiff(day, 1, getdate()), 0))) and DYYYY = @YearToGet group by DIVISION, SDESCR, DYYYY ), q_01 as ( select DIVISION , SDESCR , DYYYY , sum(APRICE) as YESales , sum(PARTY) as YEPAX , sum(NetAmount) as YENetSales , sum(InsAmount) as YEInsSales , sum(CancelRevenue) as YECXSales , sum(OtherAmount) as YEOtherSales , sum(CXVALUE) as YECXValue from dbo.B101BookingsDetails where DYYYY=@YearToGet group by DIVISION, SDESCR, DYYYY ), q_02 as ( select DIVISION , SDESCR , DYYYY , sum(APRICE) as CurrentSales , sum(PARTY) as CurrentPAX , sum(NetAmount) as CurrentNetSales , sum(InsAmount) as CurrentInsSales , sum(CancelRevenue) as CurrentCXSales , sum(OtherAmount) as CurrentOtherSales , sum(CXVALUE) as CurrentCXValue from dbo.B101BookingsDetails where Booked <= CONVERT(int,DateAdd(year, (year( getdate() )) - Year(getdate()), DateAdd(day, DateDiff(day, 1, getdate()), 0))) and DYYYY = (year( getdate() )) group by DIVISION, SDESCR, DYYYY ) select a.DIVISION , a.SDESCR , a.DYYYY , asofSales , asofPAX , YESales , YEPAX , CurrentSales , CurrentPAX , asofsales/ ISNULL(NULLIF(yesales,0),1) as percentsales , asofpax/yepax as percentpax ,currentsales/ISNULL(NULLIF((asofsales/ISNULL(NULLIF(yesales,0),1)),0),1) as projectedsales ,currentpax/ISNULL(NULLIF((asofpax/ISNULL(NULLIF(yepax,0),1)),0),1) as projectedpax from q_00 as a join q_01 as b on (b.DIVISION = a.DIVISION and b.SDESCR = a.SDESCR and b.DYYYY = a.DYYYY) join q_02 as c on (b.DIVISION = c.DIVISION and b.SDESCR = c.SDESCR) order by a.DIVISION, a.SDESCR, a.DYYYY ; select a.DIVISION , a.SDESCR , a.DYYYY , asofPAX , asofNetSales , YEPAX , YENetSales , CurrentPAX , CurrentNetSales , asofnetsales/ ISNULL(NULLIF(yenetsales,0),1) as percentnetsales , asofpax/yepax as percentpax ,currentnetsales/ISNULL(NULLIF((asofnetsales/ISNULL(NULLIF(yenetsales,0),1)),0),1) as projectednetsales ,currentpax/ISNULL(NULLIF((asofpax/ISNULL(NULLIF(yepax,0),1)),0),1) as projectedpax from q_00 as a join q_01 as b on (b.DIVISION = a.DIVISION and b.SDESCR = a.SDESCR and b.DYYYY = a.DYYYY) join q_02 as c on (b.DIVISION = c.DIVISION and b.SDESCR = c.SDESCR) order by a.DIVISION, a.SDESCR, a.DYYYY ; select a.DIVISION , a.SDESCR , a.DYYYY , asofPAX , asofInsSales , YEPAX , YEInsSales , CurrentPAX , CurrentInsSales , asofinssales/ ISNULL(NULLIF(yeinssales,0),1) as percentsales , asofpax/yepax as percentpax ,currentinssales/ISNULL(NULLIF((asofinssales/ISNULL(NULLIF(yeinssales,0),1)),0),1) as projectedinssales from q_00 as a join q_01 as b on (b.DIVISION = a.DIVISION and b.SDESCR = a.SDESCR and b.DYYYY = a.DYYYY) join q_02 as c on (b.DIVISION = c.DIVISION and b.SDESCR = c.SDESCR) order by a.DIVISION, a.SDESCR, a.DYYYY ;

  • XML and XSLT: need it to sort only certain child nodes

    - by MT
    Hello, I need to have my XSLT stylesheet sort my XML file's child nodes, but only certain ones. Here's an example of what the XML is like: <?xml version="1.0"?> <xmltop> <child1 num="1"> <data>12345</data> </child1> <child1 num="2"> <data>12345</data> </child1> <child2 num="3"> <data>12345</data> </child2> <child2 num="2"> <data>12345</data> </child2> <child2 num="1"> <data>12345</data> </child2> </xmltop> And this is the XSL file I'm using: <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="/xmltop"> <xsl:copy> <xsl:apply-templates> <xsl:sort select="@num"/> </xsl:apply-templates> </xsl:copy> </xsl:template> <xsl:template match="child2"> <xsl:copy-of select="."/> </xsl:template> </xsl:stylesheet> This creates problems for me because the nodes are stripped of their tags, and their contents remain, making my XML invalid. I'm not really an expert at XSL so pardon me if this is a dumb question. The <child2>'s are sorted properly. Thank you.
