• iPhone app launch times and Core Data migration

  - by sehugg

  I have a Core Data application which I plan to update with a new schema. The lightweight migration seems to work, but it takes time proportional to the amount of data in the database. This occurs in the didFinishLaunchingWithOptions phase of the app. I want to avoid <app> failed to launch in time problems, so I assume I cannot keep the migration in the didFinishLaunchingWithOptions method. I assume the best method would involve performing the migration in a background thread. I assume also that I'd need to defer loading of the main ViewController until the loading completes to avoid using the managedObjectContext until initialization completes. Does this make sense, and is there example code (maybe in Apple sample projects) of this sort of initialization?

• In ASP.NET MVC Should A Form Post To Itself Or Another Action?

  - by Sohnee

  Which of these two scenario's is best practice in ASP.NET MVC? 1 Post to self In the view you use using (Html.BeginForm) { ... } And in the controller you have [HttpGet] public ActionResult Edit(int id) [HttpPost] public ActionResult Edit(EditModel model) 2 Post from Edit to Save In the view you use using (Html.BeginForm("Save", "ControllerName")) { And in the controller you have [HttpGet] public ActionResult Edit(int id) [HttpPost] public ActionResult Save(EditModel model) Summary I can see the benefits of each of these, the former gives you a more restful style, with the same address being used in conjunction with the correct HTTP verb (GET, POST, PUT, DELETE and so on). The latter has a URL schema that makes each address very specific. Which is the correct way to do this?

• Membership and asp.net MVC

  - by Jemes

  I’m building a site that needs users created with different roles and permissions to access different areas of the site. I using mvc 2 but I can’t find much clear guidance on using the Membership tool with mvc to create accounts and roles etc. I tried the web configuration tool which works but I would like to administrate the site remotely. I used the aspnet_regsql tool so I can access the SqlMembershipProvider Schema in my Database. I also need to add more information to a user like profile info and a picture, would I add these to the membership tables or create separate tables for this? Any advice or help would be really helpful? Thanks Jemes

• Insert hex string value to sql server image field is appending extra 0

  - by rotary_engine

  Have an image field and want to insert into this from a hex string: insert into imageTable(imageField) values(convert(image, 0x3C3F78...)) however when I run select the value is return with an extra 0 as 0x03C3F78... This extra 0 is causing a problem in another application, I dont want it. How to stop the extra 0 being added? The schema is: CREATE TABLE [dbo].[templates]( [templateId] [int] IDENTITY(1,1) NOT NULL, [templateName] [nvarchar](50) NOT NULL, [templateBody] [image] NOT NULL, [templateType] [int] NULL) and the query is: insert into templates(templateName, templateBody, templateType) values('I love stackoverflow', convert(image, 0x3C3F786D6C2076657273696F6E3D.......), 2) the actual hex string is quite large to post here.

• Hibernate pluralization

  - by matiasf

  I have A MySQL database currently in production use for a CakePHP application A Java SE application accessing the same database via Hibernate, currently in development. I'm using the Netbeans "automigrate" feature to create the POJO classes and XML files (do I really need the XML files when using annotations?). As the schema is quite complex creating the tables manually is way too much work. Cake expects all DB tables to be pluralized (the Address class is automagically mapped to the addresses table). When running the Netbeans automigration it then does pluralization on the already pluralized table names (I'm getting Addresses.java and setAddresseses() methods). I know I'm asking for trouble running two very different data layers against the same database, but I'd like to know if it's possible to have Netbeans generating the POJO classes in singular form or if there is another (better) way to manage this.

• Multi join query returns to many results and improperly matched

  - by Woot4Moo

  I have the following minimal schema in Oracle: http://sqlfiddle.com/#!4/c1ed0/14 The queries I have run yield too many results and this query: select cat.*, status.*, source.* from cats cat, status status, source source Left OUTER JOIN source source2 on source2.sourceid = 1 Right OUTER JOIN status status2 on status2.isStray =0 order by cat.name will yield incorrect results. What I am expecting is a table that looks like the following however I cannot seem to come up with the correct SQL. NAME AGE LENGTH STATUSID CATSOURCE ISSTRAY SOURCEID CATID Adam 1 25 null null null 1 2 Bill 5 1 null null null null null Charles 7 5 null null null null null Steve 12 15 1 1 1 1 1 In plain English what I am looking for is to return all known cats + their associated cat source + their cat status while retaining null values. The only information I will have is the source that I am curious about. I also only want the cats that have a status of either STRAY or UNKNOWN (null)

• Returning multiple aggregate functions as rows

  - by SDLFunTimes

  I need some help formulating a select statement. I need to select the total quantity shipped for each part with a distinct color. So the result should be a row with the color name and the total. Here's my schema: create table s ( sno char(5) not null, sname char(20) not null, status smallint, city char(15), primary key (sno) ); create table p ( pno char(6) not null, pname char(20) not null, color char(6), weight smallint, city char(15), primary key (pno) ); create table sp ( sno char(5) not null, pno char(6) not null, qty integer not null, primary key (sno, pno) );

• Export Multiple Sheets to Excel Through Browser

  - by ProfK

  I need to export multiple data tables to Excel on the clients machine, each to their own sheet. If it was just one sheet, I'd use the Excel/csv content type, but I've heard something about an XML format that can represent an entire workbook. I don't want to go down the Packaging and .xlsx route, so I need standard .xls. Our bug tracker, Gemini, used to have an export function that produced an XML file that Excel automatically opened as a multi-sheet workbook, but I can't find it. Is there still such a mechanism, and where can I find that schema?

• SQL Compare-Like tool for Oracle?

  - by Hitchhiker

  We're a .NET team which uses the Oracle DB for a lot of reasons that I won't get into. But deployment has been a bitch. We are manually keeping track of all the changes to the schema in each version, by keeping a record of all the scripts that we run during development. Now, if a developer forgets to check-in his script to the source control after he ran it - which is not that rare - at the end of the iteration we get a great big headache. I hear that SQL Compare by Red-Gate might solve these kind of issues, but it only has SQL Server support. Anybody knows of a similar tool for Oracle? I've been unable to find one.

• EntityFramework: Access dabase-column using user defined Type

  - by Nils

  I "inherited" an old Database where dates are stored as Int32 values (times too, but dates shall suffice for this example) i.e. 20090101 for Jan. 1st 2009. I can not change the schema of this database because it is still accessed by the old programs. However I want to write a new program using EF as the O/R-M. Now I'd love to have DateTime-Values in my Model. Is there a way to write a custom type and use this as a Type in the EF-Model. Something like a Type "OldDate" with properties: DatabaseValue : Int23 Value : DateTime (specifying the date-part whereas the time-part is always 0:00:00) Is something like this possible with the EF-Model ?

• ASP.Net WebSite Membership AND C# Windows Form Membership

  - by user1638362

  This is not real, it's just a project i'm working on I've created a Hotel Management system in C# WindowsForm, it allows staff members to Add/Edit/Update Rooms,Reservation and Customers etc. Along side this Windows-form i'm creating an ASP.net WebSite where customers should be able to register and reserve rooms online. I've come to the point where i need to create some-type of membership method for this website which should correspond to the membership of the windows form. However i'm not sure what method of membership would be best suited for this, i have looked into the asp.net membership, it's what i want however it creates it's own schema and i don't know how i can relate the information to my customers table and c#windows form. I would ideally like it to resemble a real-life situation as much as possible anyway, am i going about this the wrong way? in terms of the c# windows-form what other technology would a business use to manage a system like this where they can add/edit/update there system and have a website which relates. What are my options here?

• Consolidating values in a junction table

  - by senloe

  I have the following schema: Parcels Segments SegmentsParcels ========= ========== ================= ParcelID SegmentID ParcelID ... Name SegmentID ... id A user of the data wants to consolidate Segments.Names and gave me a list of current Segment.Names mapped to new Segment.Names (all of which currently exist). So now I have this list in a temporary table with the currentID and newID to map to. What I want to do is update the SegmentID in SegmentsParcels based on this map. I could use the statement: update SegmentParcels set segmentID = [newID] from newsegments where segmentID = currentid but this will create some duplicates I have a unique constraint on ParcelID and SegmentID in SegmentParcels. What is the best way to go about this? I considered removing the constraint and then dealing with removing the duplicates (which I did at one point and could probably do again) but I was hoping there was a simpler way.

• As a team should we develop locally and merge into the dev server, or develop on the dev server?

  - by CogitoErgoSum

  Hey, Recently I was tasked with writing up formal procedures for a team based development enviroment. We have several projects with multiple modules each. Right now there are only two programmers, however there are plans to expand to 4-6 programmers. Each programmer will be working on the same project and possibly pages which may cause over writing or error issues. So far the ideal solution I have thought up is: Local development (WAMP/VM or some virtual server instance on their own machine). Once a developer has finished their developments, they check it into the CVS Repository and merge it wih other fixes etc. The CVS version is then deployed to the primary dev server for testing by the devs. The MySQL DAtabases are kept on the primary dev server and users may remotely connect to it. Any Schema / Data alterations are run through a DB Admin who will notify all devs of any DB Changes (Which should be rare). Does anyone see an issue with this or have a better solution?

• Rails 2.3.5 table populated by fixtures at end of test run rather than at start

  - by rlandster

  I start with a test database containing the schema but with no data in the tables. I run a test like so cd test/ ruby unit/directive_test.rb I get failures indicating that the code found no data in the data tables. However, I look at the tables after running that test and the data is now in the the table. In fact, if I immediately run the test again I get no failures. So it appears that the fixture is being loaded into the table too late for one of my modules to find it. When are the fixtures loaded? After or before the app/model/*.rb files are executed? If it is after the models are executed is there a way to delay the loading? This issue is also relevant when running rake test:units since that task clears the test data after it finished.

• Maintaining the position of columns in Grails/GORM

  - by firnnauriel

  Is there a way to fix the position of the columns in a domain? I have this domain: class SnbrActVector { int nid String term double weight static mapping = { version false id(generator: 'assigned') } static constraints = { nid(blank:false) term(blank:false) weight(blank:false) } } This is the schema of the table generated: CREATE TABLE `fractor_grailsDEV`.`snbr_act_vector` ( `id` bigint(20) NOT NULL, `weight` double NOT NULL, `term` varchar(255) COLLATE utf8_unicode_ci NOT NULL, `nid` int(11) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci It seems that the order of the columns were reversed. Is there a way to make it like this? (order is nid, term, weight) CREATE TABLE `fractor_grailsDEV`.`snbr_act_vector` ( `id` bigint(20) NOT NULL, `nid` int(11) NOT NULL, `term` varchar(255) COLLATE utf8_unicode_ci NOT NULL, `weight` double NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci

• Is there a way to query if array field contains a certain value in Doctrine2?

  - by dpimka

  Starting out with Symfony2 + Doctrine. I have a table with User objects (fos_user), for which my schema contains a roles column of an 'array' type. Doctrine saves fields of this type by serializing them from php 'array' to 'longtext' (in mysql's case). So let's say I have the following users saved into DB: **User1**: array(ROLE_ADMIN, ROLE_CUSTOM1) **User2**: array(ROLE_ADMIN, ROLE_CUSTOM2) **User3**: array(ROLE_CUSTOM2) Now in my controller I want to select all users with ROLE_ADMIN set. Is there a way to write a DQL query which would directly return me User1 and User2? Or do I need to fetch all users to have Doctrine to unserialize roles column and then for each of them do in_array('ROLE_ADMIN', $user-getRoles())? I have searched the DQL part of the manual, but so far did not find anything similar to my needs...

• [Symfony] Admin generator and i18n

  - by David

  I have read lots of questions about i18n, but I haven't found any about performance. I have a simple backend app listing the contents of an ads table. These ads have a category, that is translated in some languages (it's defined as i18n in the Doctrine schema). So, when I add a "table_method" in my generator.yml to include de Category table, it reduces the number of queries, but there are yet some of them referencing i18n translation tables. So, if I add the category Translation table to the query, it reduces even more the queries BUT it increases the processing time considerably. Why this time penalty? Just because of the translation table? And why isn't the filter using this method to avoid so many translation queries as well? I mean, if I want to filter by category, it is making one query per category to include the translation table. Why??

• Export MySQL Data as Insert Statements

  - by gav

  Hi All, I'm working in Ubuntu with MySql and I also have Query Browser and Administrator installed, I'm not afraid of the command line either if it helps. I want simply to be able to run a query and see a result set but then convert that result set into a series of commands that could be used to create the same rows in a table of an identical schema. I hope the question makes sense, it's quite a simple problem and one that must have been solved but I can't for the life of me work out where this kind of conversion is made available. Thanks in advance, Gav

• What is the technological basis for Azure DocumentDB?

  - by user1703840

  Microsoft announced the availability of Azure DocumentDB as follows... A fully-managed, highly-scalable, NoSQL document database service. - Rich query over a schema-free JSON data model - Transactional execution of JavaScript logic - Scalable storage and throughput - Tunable consistency - Rapid development with familiar technologies - Blazingly fast and write optimized database service I really like the "transactional execution of JavaScript logic". Sounds like an approach similar to that of PostgreSQL NoSQL. Anyone know what is the technological basis for the Azure DocumentDB service? SQL Server?

• Clone a lua state

  - by hbxfnzwpf

  Recently, I have encountered many difficulties when I was developing using C++ and Lua. My situation is: for some reason, there can be thousands of Lua-states in my C++ program. But these states should be same just after initialization. Of course, I can do luaL_loadlibs() and lua_loadfile() for each state, but that is pretty heavy(in fact, it takes a rather long time for me even just initial one state). So, I am wondering the following schema: What about keeping a separate Lua-state(the only state that has to be initialized) which is then cloned for other Lua-states, is that possible?

• Java Webservice with generic methods

  - by danby

  Hi, I was wondering if it is possible to make a generic webservice method in java like this: @WebMethod public <T extends Foo> void testGeneric(T data){ However when I try to consume this with a Java client I get an error stating: [ERROR] Schema descriptor {http://####/}testGeneric in message part "parameters" is not defined and could not be bound to Java. I know it is possible to make a method that takes a parameter such as List and this generates correctly using JAX-WS. I don't mind if there is a solution that means I am tied to using only a particular technology. Thanks, Dan.

• Select an entity according to a list of associated entities

  - by Maverickch

  I have the following database schema : Two tables, books and tags, with n-m relationship. Books - Tags We can have for example the book 1, with tags {A,B,C}, and book 2, with tags {A}. I would like to select the books according to a list of tags. For example : selected tags list : {A,B} - book 1 My idea was to use the MINUS SQL function, to subtract book tags list to the selected tags list, and return the book if the list was empty. Unfortunately, this SQL function is not supported by HQL. Any idea about that ?
