• design suggestion for a message decoder in delphi

  - by stanleyxu2005

  Hi All, I want to implement a RPC module. Different requests are encoded as JSON objects. They will be decoded and then be handled by a request handler. At last a corresponding response will be returned. The demo code looks as follows: type IRequestHandler = interface function Handle(const Request: TAaaRequest): TResponse; function Handle(const Request: TBbbRequest): TResponse; end; TDecoder = class class function Decode(const Json: TJsonObject; const RequestHandler: IRequestHandler): TResponse; end; class function TDecoder.Decode(const Json: TJsonObject; const RequestHandler: IRequestHandler): TResponse; var Method: string; Request: TObject; begin Method := Json['method'].AsString; if (Method = TAaaRequest.ClassName) then begin Request := TAaaRequest.FromJSON(Json); // Casted as TObject if Request <> nil then begin Result := RequestHandler.Handle(TAaaRequest(Request)); Request.Free; end; end else if (Method = TBbbRequest.ClassName) then begin Request := TBbbRequest.FromJSON(Json); // Casted as TObject if Request <> nil then begin Result := RequestHandler.Handle(TBbbRequest(Request)); Request.Free; end; end else Result := CreateErrorResponse('Unknown method: ' + Json.ToString); end; According to the code, the handling of different request types are very similar. If I have 100 different request types, I have to copy and paste the above code block 100 times. This is not clever. I am looking for a better way to do the same logic. My imagination is as follows: TDecoder = class private FRequestTypes: TDictionary<string, TClassInfo>; // Does this work? public constructor Create; destructor Destroy; override; function Decode(const Json: TJsonObject; const RequestHandler: IRequestHandler): TResponse; end; constructor TDecoder.Create; begin FRequestTypes := TDictionary<string, TClassInfo>.Create; FRequestTypes.Add(TAaaRequest.ClassName, TAaaRequest); // Does this work? FRequestTypes.Add(TBbbRequest.ClassName, TBbbRequest); end; destructor TDecoder.Destroy; begin FRequestTypes.Free; inherited; end; function TDecoder.Decode(const Json: TJsonObject; const RequestHandler: IRequestHandler): TResponse; var Method: string; Info: TClassInfo; Request: TObject; begin Method := Json['method'].AsString; if FRequestTypes.ContainsKey(Method) then begin // An universal way Info := FRequestTypes[Method]; Request := Info.FromJSON(Json); // Casted as TObject if Request <> nil then begin Result := RequestHandler.Handle(Info(Request)); // Casted to corresponding class type (e.g. TAaaRequest or TBbbRequest) Request.Free; end; end else Result := CreateErrorResponse('Unknown method: ' + Json.ToString); end; I do not know, if I can write an universal way to handle a great number of different request types. Development environment Delphi 2010. Any hint is appreciated.

• PHP sorting issue with simpleXML

You can see that in the array I can make it sort by the attribute 'statename'. What I am having trouble with is echoing out and combining the two functions in order to have it auto sort both the states and the cities within and forming the needed optgroups. I tried copying the lines for the cities and changing the names called several ways to no avail.

• Problem loading Oracle client libraries when running in a NAnt build

  - by Chris Farmer

  I am trying to use dbdeploy to manage Oracle schema changes. I can run it successfully from the command line to get it to generate my change scripts, but when I try to execute it via the dbdeploy NAnt task running through TeamCity, I get an error: System.Data.OracleClient requires Oracle client software version 8.1.7 or greater. I do have the Oracle 10.2.0.2 client software installed. It's the first entry in the system path, and the dbdeploy.exe app is able to successfully negotiate an Oracle connection. The dbdeploy code dynamically loads the System.Data.OracleClient assembly, which in-turn tries to use the Oracle client bits to talk to the database. This is what is failing in my NAnt environment. I have verified the following points: The same user identity is running the process in both cases The same working directory is used in both cases The same dbdeploy code is running in both cases and with the same supplied parameters The same database connection string is being used in both cases The same ADO.NET assembly is being dynamically loaded in both cases (System.Data.OracleClient, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089) Here's the top of the stack trace during the error: at System.Data.OracleClient.OCI.DetermineClientVersion() at System.Data.OracleClient.OracleInternalConnection.OpenOnLocalTransaction (String userName, String password, String serverName, Boolean integratedSecurity, Boolean unicode, Boolean omitOracleConnectionName) at System.Data.OracleClient.OracleInternalConnection..ctor( OracleConnectionString connectionOptions) at System.Data.OracleClient.OracleConnectionFactory.CreateConnection( DbConnectionOptions options, Object poolGroupProviderInfo, DbConnectionPool pool, DbConnection owningObject) at System.Data.ProviderBase.DbConnectionFactory.CreatePooledConnection( DbConnection owningConnection, DbConnectionPool pool, DbConnectionOptions options) at System.Data.ProviderBase.DbConnectionPool.CreateObject( DbConnection owningObject) at System.Data.ProviderBase.DbConnectionPool.UserCreateRequest( DbConnection owningObject) at System.Data.ProviderBase.DbConnectionPool.GetConnection( DbConnection owningObject) at System.Data.ProviderBase.DbConnectionFactory.GetConnection( DbConnection owningConnection) at System.Data.ProviderBase.DbConnectionClosed.OpenConnection( DbConnection outerConnection, DbConnectionFactory connectionFactory) at System.Data.OracleClient.OracleConnection.Open() at Net.Sf.Dbdeploy.Database.DatabaseSchemaVersionManager. GetCurrentVersionFromDb() My main question is this: how can I discover what's different about these running environments to see why my Oracle client software can't be loaded?

• Komodo Edit 5.2 Django Template Syntax Error - Info: <head> previously mentioned

  - by Lance McNearney

  I am using Komodo Edit 5.2 for editing html and Django template files. It always shows a single syntax error inside the first {% block %} area on the first tag of my template. For example: {% extends "base.html" %} {% load i18n %} {% block title %}Hello{% endblock %} {% block content %} <p>Hello</p> <-- Syntax error on this single line <p>Other lines have no errors</p> {% endblock %} {% block footer %} <p>No errors here</p> {% endblock %} The syntax error given is: Info: <head> previously mentioned I know for a fact that the error has nothing to do with my <head> tag since it occurs in the base template and in child templates (and the IDE isn't smart enough to process the base templates when in a child, etc.) All of my html tags are closed properly and everything validates for XHTML strict. This forum post mentions a similar problem but offers no solution (and may be specific to Smarty syntax highlighting). Any ideas on how to resolve this error (or disable it from being shown)?

• Magento MAGMI: Product attributes (custom options) not showing up in import

  - by Rodgers and Hammertime

  When importing a CSV into Magento with the MAGMI importing tool, I am unable to import Custom Options (as in size: smalee/medium/large). The import manages to put in the basic products, but the Custom Options don't transfer accross. By custom options I mean the fields Title, Input Type, Is Required, Sort Order Title, Price, Price Type, SKU, Sort Order Title, Price, Price Type, SKU, Sort Order Title, Price, Price Type, SKU, Sort Order and so on ... Found in the custom options menu... Even using the example CSV from the MAGMI SourceForge Wiki: sku,name,description,price,Size:drop_down:1 T-Shirt1,T-Shirt,A T-Shirt,5.00,Small|Medium|Large T-Shirt2,T-Shirt2,Another T-Shirt,6.00,XS|S|M|L|XL ...it fails to import the attributes. So i'm simply using MAGMI with the supplied example data from SourceForge on a blank magento product list, and it doesn't transfer properly. Can anyone shed any light on what might be wrong? I am using Magento ver. 1.6.1.0 if that changes anything. Thanks.

• Get more debug info from AxHost?

  - by Presidenten

  Hello I'm trying to deploy an application which uses an library that embeds an ActiveX control with AxHost in C#. When I run the installed app on our test rig I catch and present the following exception: Unexpected exception. This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem. (Exception from HRESULT: 0x800736B1) at System.Windows.Forms.UnsafeNativeMethods.CoCreateInstance(Guid& clsid, Object punkOuter, Int32 context, Guid& iid) at System.Windows.Forms.AxHost.CreateWithoutLicense(Guid clsid) at System.Windows.Forms.AxHost.CreateWithLicense(String license, Guid clsid) at System.Windows.Forms.AxHost.CreateInstanceCore(Guid clsid) at System.Windows.Forms.AxHost.CreateInstance() at System.Windows.Forms.AxHost.GetOcxCreate() at System.Windows.Forms.AxHost.TransitionUpTo(Int32 state) at System.Windows.Forms.AxHost.CreateHandle() at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible) at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible) at System.Windows.Forms.AxHost.EndInit() at ....InitializeComponent() at ... I googled 0x800736B1, so I know that it means that a file could not be loaded. The big Q right now is how to find out which file it is that cant be loaded. Is there some sort of logging function I can turn on, or is there maybe som way I can get more info from the exception?

• problem getting info from a cookie with javascript

  - by Jason

  I am having an issue with my cookies and I can't figure it out. Basically I have it set up so it checks for the cookie to see if the user is logged in, and then displays either a welcome message or a login link. It works - except that instead of returning the persons name in the welcome message it just is blank where the name should be. The cookie is there, with all the appropriate info.. not sure what I am doing wrong. var itm = new Array(); itm[0] = findCookie("ui"); if (itm[0] == null) { document.write("<h2><a href='logreg.html'>Log In or Sign Up</a></h2>"); } else { var c1 = itm[0].indexOf(","); var c2 = itm[0].indexOf(",",c1); var c3 = itm[0].indexOf(",",c2); var gname = itm[0].substring(c2,c3); document.write("<h2>Welcome "+gname+"!</h2>"); } The findCookie function is.. function findCookie(val){ var cookie = null; var findVal = val + "="; var dc = document.cookie; if (dc.length > 0) { var start = dc.indexOf(findVal); if (start >= 0) { start += findVal.length; lastVal = dc.indexOf(";", start); if (lastVal == -1) { lastVal = dc.length; } cookie = (dc.substring(start, lastVal)); } else { return cookie; } } return cookie; }

• bash - how to filter java exception info

  - by Michael Mao

  Hi all: We've got a multi-agent Java environment where different agent would most likely produce all sorts of exceptions thrown to stderr. Here is a sample taken from the huge exception log **java.security.AccessControlException: access denied (java.io.FilePermission ..\tournament\Driver\HotelRoomAnalyser.class read)** at java.security.AccessControlContext.checkPermission(Unknown Source) at java.security.AccessController.checkPermission(Unknown Source) at java.lang.SecurityManager.checkPermission(Unknown Source) at java.lang.SecurityManager.checkRead(Unknown Source) at java.io.File.length(Unknown Source) at emarket.client.EmarketSandbox$SandboxFileLoader.loadClassData(EmarketSandbox.java:218) at emarket.client.EmarketSandbox$SandboxFileLoader.loadClass(EmarketSandbox.java:199) at java.lang.ClassLoader.loadClass(Unknown Source) **java.security.AccessControlException: access denied (java.io.FilePermission ..\tournament\Driver\HotelRoomAnalyser.class read)** at java.security.AccessControlContext.checkPermission(Unknown Source) at java.security.AccessController.checkPermission(Unknown Source) at java.lang.SecurityManager.checkPermission(Unknown Source) at java.lang.SecurityManager.checkRead(Unknown Source) at java.io.File.length(Unknown Source) at emarket.client.EmarketSandbox$SandboxFileLoader.loadClassData(EmarketSandbox.java:218) at emarket.client.EmarketSandbox$SandboxFileLoader.loadClass(EmarketSandbox.java:199) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClassInternal(Unknown Source) at MySmarterAgent.hotelRoomBookings(MySmarterAgent.java:108) fortunately all top-tier exceptions are denoted by no leading spaces, as wrapped by ** above. My concern is to get all of the top-tier exception name (delimited by colon :), together with the first line below which contains something like at emarket.client.EmarketSandbox$SandboxFileLoader.loadClassData(EmarketSandbox.java:218) Basically, something with padded style, starts with "at" and ends with ".java:108" So this info can be forwarded to the owner of that error-prone agent and let him/her fix it. My code in ~/.bashrc is incompleted now : alias startmatch='java -jar "emarket.jar" ../tournament 100'; function geterrors() { startmatch 2>"$1"; a=0; while read line do if true; then a=$(($a+1)); echo $a; fi; done } What it does now is to redirect all stderr to a text file specified by the first argument passed in, and after that, parse that text file line by line, if certain conditions returns true, echo only that line. And I am stuck with what to do inside the loop. Any suggestion is much appreciates, any hint is welcomed.

• Switching from Sourcesafe - What to look for in a product

  - by asp316

  We're looking to move off of sourcesafe and on to a more robust source control system for our .Net apps. We're also looking for scripted/automated deployments. I'm a .Net developer (web and winforms). However, most of our development staff is RPG for the IBM iSeries and the devs use Aldon's LMI for source control and deployment. Our manager would prefer to stick with Aldon so all of our products are in the same system. However, I don't have experience with Aldon's products on the .Net side. I've used TFS and Subversion with Tortoise a bit, but not enough to recommend one or the other, especially in comparison to Aldon's product. Does anybody have experience with Aldon's products? If so, thoughts please? Also, other than the obvious things source control systems do, are there things I should avoid or are there must haves? I'm open to any system. A bit of background, I'm the only .Net dev in our company but I let operations do the deployments. I do want the ability to support concurrent checkouts if we hire a new dev.

• Iterative Cartesian Product in Java

  - by akappa

  Hi, I want to compute the cartesian product of an arbitrary number of nonempty sets in Java. I've wrote that iterative code... public static <T> List<Set<T>> cartesianProduct(List<Set<T>> list) { List<Iterator<T>> iterators = new ArrayList<Iterator<T>>(list.size()); List<T> elements = new ArrayList<T>(list.size()); List<Set<T>> toRet = new ArrayList<Set<T>>(); for (int i = 0; i < list.size(); i++) { iterators.add(list.get(i).iterator()); elements.add(iterators.get(i).next()); } for (int j = 1; j >= 0;) { toRet.add(Sets.newHashSet(elements)); for (j = iterators.size()-1; j >= 0 && !iterators.get(j).hasNext(); j--) { iterators.set(j, list.get(j).iterator()); elements.set(j, iterators.get(j).next()); } elements.set(Math.abs(j), iterators.get(Math.abs(j)).next()); } return toRet; } ...but I found it rather inelegant. Someone has a better, still iterative solution? A solution that uses some wonderful functional-like approach? Otherwise... suggestion about how to improve it? Errors? Thanks :)

• How to make a product catalog in C#?

  - by Ervin

  I need to develop a product catalog (about 4000 products) application, which would be given to clients on CD or DVD. The catalog exists in webpage format using PHP and MySQL. IMPORTANT: the application is given to clients who maight have old PC, old System. For minimal requirements I would put Windows XP and Internet Explorer 6 (if needed). I need the following features: 1 search option (after productID AND after keyword) 2 print option (by selecting multiple products) 3 shopping cart (making a list which will be sent to an email address if there is any Internet Connection on the computer) When I was asked to do it I had 2 days to realise a very basic version, so I took the whole website and exported it in HTML pages, and developed an application in C# which contains an embeded browser. So the whole website is now static and put on a CD. Everything fine so far. Now here are the problems: 1. the search option was realized by parsing the html files and reading the productID or looking for keywords inside of them. Put on a CD it was extremely slow (searching in 600MB of html files). FOR THIS I WOULD NEED A SOLUTION WITH A STATIC DATABASE (USING ACCESS OR SOMETHING) TO HAVE INDEXED ROWS, SO THE SEARCH COULD BE A VERY FAST ONE. 2. the printing option was a simply call of the embeded Internet Explorer print functions. Here are two problems: a) user needs IE7 for printing the website scaled (FIT TO PAGE), otherwise the edges of the page are cut down. b) users of this app does not have even the basic PC usage skills, so they can't set the printing settings, so there will appear in header and footer the page numbers and titles. QUESTION: can I set these settings from CSS for printing? 3. couldn't make a a shopping cart as I don't use a database, so I have static websites and content is inside the HTML. QUESTION: WHICH ARE THE BEST SOLUTIONS FOR THE PROBLEMS DESCRIBED ABOVE? PLEASE ANSWER EVEN IF YOUR ANSWER IS FOR ONE QUESTION ONLY. THANKS

• NAnt errors when generating assembly info after project is upgraded to VS2010

  - by Grant Palin

  I have a project I recently upgraded to VS2010 - the project/solution files are updated, but I'm still targeting .NET 3.5. Until now, my standard NAnt build script has not given me any trouble. However, it appears that after updating the project, and updating the NAnt config to be aware of the new tooling, I am now receiving an error when autogenerating assembly information, which fails the build. The relevant build task is below: <asminfo output="${dir.src}\${file.commonAssemblyInfo}" language="${project.codeLanguage}"> <imports> <import namespace="System.Reflection" /> </imports> <attributes> <attribute type="AssemblyVersionAttribute" value="${project.fullversion}" /> <attribute type="AssemblyFileVersionAttribute" value="${project.fullversion}" /> <attribute type="AssemblyInformationalVersionAttribute" value="${project.fullversion}" /> <attribute type="AssemblyCopyrightAttribute" value="${assembly.copyright}" /> <attribute type="AssemblyCompanyAttribute" value="${assembly.company}" /> <attribute type="AssemblyConfigurationAttribute" value="${project.config}" /> <attribute type="AssemblyTrademarkAttribute" value="${assembly.trademark}" /> <attribute type="AssemblyProductAttribute" value="${assembly.product}" /> </attributes> </asminfo> The error is highlighted for the first line of the asminfo task. It reads: AssemblyInfo file 'C:\Users\Grant\Projects\VisualStudio\Checklist\src\CommonAssemblyInfo.cs' could not be generated. This method implicitly uses CAS policy, which has been obsoleted by the .NET Framework. In order to enable CAS policy for compatibility reasons, please use the NetFx40_LegacySecurityPolicy configuration switch. Please see http://go.microsoft.com/fwlink/?LinkID=155570 for more information. I've gathered so far that this is something new to .NET 4. Has anyone had to address this error before? Does anyone know what it is about asminfo that may be triggering the error?

• Google Maps, marker info window won't show up ?

  Hi guys, I have written this code that loops through an array of lat/long coordinates and places a marker at each of the coordinate. Everything forks fine, exempt the info window won't appear once the marker is clicked. var ExpTowerIcon = new GIcon(); ExpTowerIcon.image = "tower.png"; ExpTowerIcon.iconSize = new GSize(75, 75); ExpTowerIcon.iconAnchor = new GPoint(37, 65); ExpTowerIcon.infoWindowAnchor = new GPoint(37, 20); var marker=new Array(); for ( i=0 ; i < lat.length ; i++ ) { var MarkerPoint = new GLatLng(lat[i],long[i]); marker[i] = new GMarker(MarkerPoint,{icon:ExpTowerIcon}) map.addOverlay( marker[i] ); GEvent.addListener( marker[i] , 'click', function() { marker[i].openInfoWindowHtml('Hello!') ; }); var polyline = new GPolyline([ new GLatLng(lat[i],long[i]) , new GLatLng(lat[i+1],long[i+1]) ], "#ff0000", 5); map.addOverlay(polyline); } Any ideas?

• Any info about book "Unix Internals: The New Frontiers" by Uresh Vahalia 2nd edition (Jan 2010)

  - by claws

  This summer I'm getting into UNIX (mostly *BSD) development. I've graduate level knowledge about operating systems. I can also understand the code & read from here and there but the thing is I want to make most of my time. Reading books are best for this. From my search I found that these two books The Design and Implementation of the 4.4 BSD Operating System "Unix Internals: The New Frontiers" by Uresh Vahalia are like established books on UNIX OS internals. But the thing is these books are pretty much outdated. yay!! Lucky me. "Unix Internals: The New Frontiers" by Uresh Vahalia 2 edition (Jan 2010) is released. I've been search for information on this book. Sadly, Amazon says "Out of Print--Limited Availability" & I couldn't find any info regarding this book. This is the information I'm looking for: Table of Contents Whats new in this edition? Where the hell can I buy soft-copy of this book? I really cannot afford buying a hardcopy. How can I contact the author? I've lot of hopes & expectations on this book. I've been waiting for its release for a long time. I've sent random mails to & & requesting to have a proper website for this book. I even contacted publisher for any further information but no replies from any one. If you have any other books that you think will help me. I again repeat, I want to get max possible out of these 2.5 months summer.

• DotNetOpenAuth / WebSecurity Basic Info Exchange

  - by Jammer

  I've gotten a good number of OAuth logins working on my site now. My implementation is based on the WebSecurity classes with amends to the code to suit my needs (I pulled the WebSecurity source into mine). However I'm now facing a new set of problems. In my application I have opted to make the user email address the login identifier of choice. It's naturally unique and suits this use case. However, the OAuth "standards" strikes again. Some providers will return your email address as "username" (Google) some will return the display name (Facebook). As it stands I see to options given my particular scenario: Option 1 Pull even more framework source code into my solution until I can chase down where the OpenIdRelyingParty class is actually interacted with (via the DotNetOpenAuth.AspNet facade) and make addition information requests from the OpenID Providers. Option 2 When a user first logs in using an OpenID provider I can display a kind of "complete registration" form that requests missing info based on the provider selected.* Option 2 is the most immediate and probably the quickest to implement but also includes some code smells through having to do something different based on the provider selected. Option 1 will take longer but will ultimately make things more future proof. I will need to perform richer interactions down the line so this also has an edge in that regard. The more I get into the code it does seem that the WebSecurity class itself is actually very limiting as it hides lots of useful DotNetOpenAuth functionality in the name of making integration easier. Andrew (the author of DNOA) has said that the Attribute Exchange stuff happens in the OpenIdRelyingParty class but I cannot see from the DotNetOpenAuth.AspNet source code where this class is used so I'm unsure of what source would need to be pulled into my code in order to enable the functionality I need. Has anyone completely something similar?

• Getting Public Info about Location in Facebook Graph API

  - by Allan Deamon

  I need to get the living city of each person in a group. Including people that are not my friends. In the browser seeing facebook profile of some unknown person, they show "lives in ...", if this is set as public information. They include the link to the city object with the city id in the link. That's all that I need. But, using a facebook app that I created to use the facebook graph api, this information is not public. I can only get the user propriety 'location' from friends of my that I have permission to see it. I gave ALL the possible permissions to my app. In the api explorer, when I use it as REST, they show few informations about someone not friend of mine. https://developers.facebook.com/tools/explorer/ Also in the api explorer, when I use the FQL, it didn't works. This query works, returning the JSON with the data: SELECT uid, name FROM user WHERE username='...'; But this other query doesn't work: SELECT uid, name, location FROM user WHERE username='...'; They return a json with a error code: { "error": { "message": "(#602) location is not a member of the user table.", "type": "OAuthException", "code": 602 } } I asked for ALL the permissions options in the token. And I can get this info in the browser version of the facebook. But how can I get it with the API ?

• Using Maven for maintaining product documentation

  - by Waldheinz

  We are using Maven for building a Java server-style application. It consists of several modules (in a single Maven "reactor") which can be plugged together to generate a final product (essentially a .jar) with the features enabled that the customer needs. All the internals are documented using JavaDoc and all, but that's not what you can give to the customer to find out how to get the thing running. Currently we have an OpenOffice document which serves as end-user documentation. I'd like to integrate this documentation into the Maven build process where each module's documentation is maintained (hand-edited) together with the Module's sources and the final document can reference the required Module documentation sections, add some friendly foreword and, if possible at all, can reference into the JavaDocs. Ultimately, the document should be output as a PDF. Is there any experience on Maven plugins can help with this? Is DocBook the right tool? Maybe Latex? Or something completely different? A sound "stick with OpenOffice and some text blocks" could be an answer, too.

• popViewControllerAnimated doesn't update info iPhone SDK

  - by WrightsCS

  When I try to pop a view controller, it doesnt update info for the previous view. Example: I have a cell that displays text in a label in View1. When you click on the cell it goes to View2 (for example) When I choose an option in View2, popViewControllerAnimated is used to go back to View1, however, I want the label to now be updated with the new option in View1. My dilemma is that when I pop View2, the label in View1 does not update. Any ideas? I've tried adding a [view1 reloadData]; before the view pops, but no luck. //VIEW1 the cell that displays the label. ringLabel = [[UILabel alloc] initWithFrame: CGRectMake(25, 12.7f, 250, 20)]; ringLabel.adjustsFontSizeToFitWidth = YES; ringLabel.textColor = [UIColor blackColor]; ringLabel.font = [UIFont systemFontOfSize:17.0]; ringLabel.backgroundColor = [UIColor clearColor]; ringLabel.textAlignment = UITextAlignmentLeft; ringLabel.tag = 0; ringLabel.text = [plistDict objectForKey:@"MYOPTION"]; [ringLabel setEnabled:YES]; [cell addSubview: ringLabel]; [ringLabel release]; //VIEW2 when cell clicked CustomProfileViewController *cpvc = [CustomProfileViewController alloc]; cpvc.ringtone = [ringList objectAtIndex:indexPath.row]; [cpvc.tblCustomTable reloadData]; [self.navigationController popViewControllerAnimated:YES];

• MySql product\tag query optimisation - please help!

  - by Nige

  Hi There I have an sql query i am struggling to optimise. It basically is used to pull back products for a shopping cart. The products each have tags attached using a many to many table product_tag and also i pull back a store name from a separate store table. Im using group_concat to get a list of tags for the display (this is why i have the strange groupby orderby clauses at the bottom) and i need to order by dateadded, showing the latest scheduled product first. Here is the query.... SELECT products.*, stores.name, GROUP_CONCAT(tags.taglabel ORDER BY tags.id ASC SEPARATOR " ") taglist FROM (products) JOIN product_tag ON products.id=product_tag.productid JOIN tags ON tags.id=product_tag.tagid JOIN stores ON products.cid=stores.siteid WHERE dateadded < '2010-05-28 07:55:41' GROUP BY products.id ASC ORDER BY products.dateadded DESC LIMIT 2 Unfortunately even with a small set of data (3 tags and about 12 products) the query is taking 00.0034 seconds to run. Eventually i want to have about 2000 products and 50 tagsin this system (im guessing this will be very slooooow). Here is the ExplainSql... id|select_type|table|type|possible_keys|key|key_len|ref|rows|Extra 1|SIMPLE|tags|ALL|PRIMARY|NULL|NULL|NULL|4|Using temporary; Using filesort 1|SIMPLE|product_tag|ref|tagid,productid|tagid|4|cs_final.tags.id|2| 1|SIMPLE|products|eq_ref|PRIMARY,cid|PRIMARY|4|cs_final.product_tag.productid|1|Using where 1|SIMPLE|stores|ALL|siteid|NULL|NULL|NULL|7|Using where; Using join buffer Can anyone help?
