• How to search for a string including spaces in Objective C?

  - by AlexCu

  I have a real basic command-line program, in Objective-C, that searches for user inputed information. Unfourtunately, the code will only read the first word in series of words that the user enters. For example, if the user enters in "Apples are great", only "Apples" is kept (and hence searched later on), excluding the "are great" part of the sentence. Here's what I have so far: char enteredQuery [128]; // array 'name' to hold the scanf string NSString *searchQuery; // ending NSString to hold and compare the user inputed data NSLog(@"Enter search query:"); scanf("%s", enteredQuery); //will read the next line searchQuery = [NSString stringWithCString: enteredQuery encoding: NSASCIIStringEncoding]; //converts scanf data into a NSString type I know it's got to do with me using scanf or the character-encoder conversion, but I can't seem to figure it out. Any help in solving the problem is very appreciated! Thanks.

• Entity Framework (4.0) how to exclude a related table.

  - by Kohan

  I have just updated to using EF 4.0 where before i was using Linq 2 SQL. I have a query: var UserList = this.repository.GetUsers(); return Json(UserList, JsonRequestBehavior.AllowGet); This was generating an error: "A circular reference was detected while serializing an object of type" This prompted this code which worked fine in L2S: var UserList = this.repository.GetUsers(); foreach (User u in UserList){ u.Subscriptions = null; } return Json(UserList, JsonRequestBehavior.AllowGet); How can i stop EF from looking into the Subscriptions table, i just want the Userlist, none of the related properties and the above example does not seem to work for this. Cheers, Kohan

• Hibernate inserting into join table

  - by Karl

  I got several entities. Two of them got a many-to-many relation. When I do a bigger operation on these entities it fails with this exception: org.hibernate.exception.ConstraintViolationException: could not insert collection rows: I execute the operation i a @Transactional context. I don't do any explicit flushing i my daos. The flush is triggered by a query. In the queue are 15 elements (all of the same structure). one of them always fails (but it's always a different one (I checked) and always at a different position). Does anybody have a hint for me for what I might do wrong? My Mapping: @ManyToMany(targetEntity = CategoryImpl.class) protected Set<Category> categories = new HashSet<Category>();

• created persisted computed columns when the user defined scalar function appears to be non-determini

  - by Ralph Shillington

  I have a scalar UDF that I know to be deterministic, however SQL doesn't. Is there a way to declare it as deterministic so that I can then use it in a persisted computed column definition? further clarification: The purpose of this exercise is that I need to harvest out specific values from an XML column on the row. I can't use the value method of the xml column in my computed column definition, but I can use it in a UDF. I know the xpath query in the value method will produce the same output give the same input so while I certainly understand that not all calls to value will be deterministic I want to assert that mine is.

• Is it a good practice to perform direct database access in the code-behind of an ASP.NET page?

  - by patricks418

  Hi, I am an experienced developer but I am new to web application development. Now I am in charge of developing a new web application and I could really use some input from experienced web developers out there. I'd like to understand exactly what experienced web developers do in the code-behind pages. At first I thought it was best to have a rule that all the database access and business logic should be performed in classes external to the code-behind pages. My thought was that only logic necessary for the web form would be performed in the code-behind. I still think that all the business logic should be performed in other classes but I'm beginning to think it would be alright if the code-behind had access to the database to query it directly rather than having to call other classes to receive a dataset or collection back. Any input would be appreciated.

• Network ActiveRecord relation with Rails

  - by Zag zag..

  Hi, I have a has and belongs to many relation between User and Article models, and I would like to link them even if an article if not hosted on the same database then a user. For example, If an article exists at foo.com/articles/3 and a user exists at bar.com/users/1, If would like to be able to do from foo.com web interface or bar.com web interface this kind of query: a_user.articles (or an_article.users). I think this can be possible adding a field like "url" in users and articles tables. But I don't know how to process for ActiveRecord. My Article model looks like this: class Article < ActiveRecord::Base has_and_belongs_to_many :users end Is there yet some example of project using this kind of relation over internet? Many thanks

• SQL Server (TSQL) - Is it possible to EXEC statements in parallel?

  - by Investor5555

  SQL Server 2008 R2 Here is a simplified example: EXECUTE sp_executesql N'PRINT ''1st '' + convert(varchar, getdate(), 126) WAITFOR DELAY ''000:00:10''' EXECUTE sp_executesql N'PRINT ''2nd '' + convert(varchar, getdate(), 126)' The first statement will print the date and delay 10 seconds before proceeding. The second statement should print immediately. The way T-SQL works, the 2nd statement won't be evaluated until the first completes. If I copy and paste it to a new query window, it will execute immediately. The issue is that I have other, more complex things going on, with variables that need to be passed to both procedures. What I am trying to do is: Get a record Lock it for a period of time while it is locked, execute some other statements against this record and the table itself Perhaps there is a way to dynamically create a couple of jobs? Anyway, I am looking for a simple way to do this without having to manually PRINT statements and copy/paste to another session. Is there a way to EXEC without wait / in parallel?

• Index for wildcard match of end of string

  - by Anders Abel

  I have a table of phone numbers, storing the phone number as varchar(20). I have a requirement to implement searching of both entire numbers, but also on only the last part of the number, so a typical query will be: SELECT * FROM PhoneNumbers WHERE Number LIKE '%1234' How can I put an index on the Number column to make those searchs efficient? Is there a way to create an index that sorts the records on the reversed string? Another option might be to reverse the numbers before storing them, which will give queries like: SELECT * FROM PhoneNumbers WHERE ReverseNumber LIKE '4321%' However that will require all users of the database to always reverse the string. It might be solved by storing both the normal and reversed number and having the reversed number being updated by a trigger on insert/update. But that kind of solution is not very elegant. Any other suggestions?

• Solution for using `this` keyword in ajax calls within methods?

  - by dqhendricks

  I am creating a JavaScript class. Some of the methods contain AJAX calls using JQuery. The problem I am comming accross is that I cannot use the this keyword within the AJAX callbacks due to a change in scope. I have come up with a hackey solution, but I am wondering what is the best practice way around this? Here is an example: var someClass = function() { var someElement = $('form'); this.close = function() { someElement.remove(); }; this.query = function() { $.ajax({ url: someurl, success: function() { this.close(); // does not work because `this` is no longer the parent class } }); }; };

• Indexing a method return (depending on Internationalization)

  - by Hedde

  Consider a django model with an IntegerField with some choices, e.g. COLORS = ( (0, _(u"Blue"), (1, _(u"Red"), (2, _(u"Yellow"), ) class Foo(models.Model): # ...other fields... color = models.PositiveIntegerField(choices=COLOR, verbose_name=_(u"color")) My current (haystack) index: class FooIndex(SearchIndex): text = CharField(document=True, use_template=True) color = CharField(model_attr='color') def prepare_color(self, obj): return obj.get_color_display() site.register(Product, ProductIndex) This obviously only works for keyword "yellow", but not for any (available) translations. Question: What's would be a good way to solve this problem? (indexing method returns based on the active language) What I have tried: I created a function that runs a loop over every available language (from settings) appending any translation to a list, evaluating this against the query, pre search. If any colors are matched it converts them backwards into their numeric representation to evaluate against obj.color, but this feels wrong.

• Stored Procedure Permissions Problem

  - by JimR

  I have migrated a set of SQL 2000 databases to SQL 2008. Most is working well, however I have some stored procedures that scheduled and run by SQL Server Agent jobs that are giving me troubles. Many of the scheduled stored procedures work, but the stored procs that access a database other than the default databases are failing with the following message: Executed as user: XYZ\YadaYada. The server principal: "XYZ\YadaYada" is not able to access the database "MyOtherDatabaseOnSameServer" under the current security context. [SQL STATE 08004](Error 619) The step failed. Obviously, I changed the names to protect the guilty. The account is a user in all of the relavent databases and is a memeber of db_owner, db_datareader, and db_datawriter. When I run these same procedures from a query window in SMS using the same accounts (I have tried many) they work fine. What am I missing?

• MySQL LEFT JOIN, GROUP BY and ORDER BY not working as required

  - by Simon

  I have a table 'products' => ('product_id', 'name', 'description') and a table 'product_price' => ('product_price_id', 'product_id', 'price', 'date_updated') I want to perform a query something like SELECT `p`.*, `pp`.`price` FROM `products` `p` LEFT JOIN `product_price` `pp` ON `pp`.`product_id` = `p`.`product_id` GROUP BY `p`.`product_id` ORDER BY `pp`.`date_updated` DESC As you can probably guess the price changes often and I need to pull out the latest one. The trouble is I cannot work out how to order the LEFT JOINed table. I tried using some of the GROUP BY functions like MAX() but that would only pull out the column not the row. Thanks.

  I have a rails application that is using thinking_sphinx for the searching. My problem is that the result returned is sorted with capitals first and lower case after it at the bottom. I'd like to mix them so that both 'A' and 'a' comes before 'B'.

• Working with three dimensional data in an HTML (ASP.NET) table.

  - by ProfK

  I am working on the prototype for a scheduling application on an intranet system. The application is for scheduling and tracking promotional workers at various locations on various dates (hence location, date, workers dimensions). Currently, only for prototyping, I am generating a data table of location/date, and from this I iteratively build an HTML table (asp:Table control). On visiting each cell, I query for people working that location-date and populate the cell accordingly. This is very inefficiant, and will at worst be improved by querying cached data for the whole location/date grid. I'm looking around for established patterns and techniques for dealing with scenarios like this in HTML in general, maybe a visualisation library for jQuery or something, and for ASP.NET in particular, maybe a library for implementation on a GridView etc. Am I going in the right direction with this, and if so, what recomendations are there regarding the previous paragraph?

• Linq to SQL and Realtime Data

  - by Jeremy

  I have an application that needs to constantly (every 50ms), call to an MVC action, and pickup/drop off data. I am using Linq to SQL and MVC because of how simple they are to implement, and I know that they aren't perfect when it comes to performance, but it works relatively well, but the best speed I can get with my current approach is 200ms (without requests overlapping). Each call to the site will create a new instance of the datacontext, query/insert it and return that data. Is there a way to have the datacontext static, but submitchanges say every 5 seconds, so that i am pretty much hitting an in-memory version of the data?
