• Application with two UITabBarControls

  - by kovpas

  Hello, I want to create an app, whith the following structure: UITabBarController ..UINavigationController ....UITabBarController So, in other words, I want to load first UITabbarController as my main ViewController, that appears on application start, in its' first tab there's a UINavigationController with a table, which shows another UITabBarController by pressing on a table cell. I started Tab Based application, set first tab to UINavigationController, and its ViewController to my TableViewController. I also created second UITabBarController in Interface Builder. Created a separate class for this controller. Everything works fine at start - my first UITabBarController is shown perfectly, but when I'm trying to push my second UITabBarController, using my UINavigationController, it looks like nothing is loaded from a .xib file - there are just an empty TabBar and NavigationBar pushed. Seems, that something is wrong with an architecture, but I can't figure out the problem. Thanks in advance and I'm sorry for my poor English. Please let me know if something is not clear, I'll try to rephrase it :).

• CodeIgniter & Datamapper as frontend, Django Admin as backend, database tables inconsistent

  - by Rasiel

  I created a database for a site i'm doing using Django as the admin backend. However because the server where the site is hosted on, won't be able to support Python, I find myself needing to do the front end in PHP and as such i've decided to use CodeIgniter along with Datamapper to map the models/relationship. However DataMapper requires the tables to be in a specific format for it to work, and Django maps its tables differently, using the App name as the prefix in the table. I've tried using the prefix & join_prefix vars in datamapper but still doesn't map them correctly. Has anyone used a combination of this? and if so how have the fixed the issue of db table names being inconsistent? Is there anything out there that i can use to make them work together?

• NHibernate Many-To-One on Joined Sublcass with Filter

  - by Nathan Roe

  I have a class setup that looks something like this: public abstract class Parent { public virtual bool IsDeleted { get; set; } } public class Child : Parent { } public class Other { public virtual ICollection<Child> Children { get; set; } } Child is mapped as a joined-subclass of Parent. Childen is mapped as a Many-To-One bag. The bag has a filter applied to it named SoftDeletableFilter. The filter mapping looks like: <filter-def name="SoftDeleteableFilter" condition="(IsDeleted = 0 or IsDeleted is null)" /> That problem is that when Other.Children is loaded the filter is being applied to the Child table and not the parent table. Is there any way to tell NHibernate to apply the filter to the parent class?

• SQL Server CE, Visual Studio 2008/2010 RC, and Linq-to-Sql

  - by blu

  I added an .sdf to my project, added a table, added a Linq-to-Sql dmbl, and tried to add the table to the dbml. The result was an error: "The selected object(s) are an unsupported data provider" This happens in both VS 2008 Professional SP1 and 2010 RC Ultimate. I found someone talking about using SQL Metal to generate the file, but I didn't enjoy that 2 years ago, and after a little playing around I recall why. Does anyone know if this is going to be supported in the release version? Should I abandon SQL Server CE and just use SQLite (with DbLinq)? Thanks for any insight.

• Can't get SubSonic insert to work

  - by Darkwater23

  I'm trying to insert a record into a table without using the SubSonic object in a VB.Net Windows app. (It will take too long to explain why.) Dim q As New SubSonic.Query("tablename") q.QueryType = SubSonic.QueryType.Insert q.AddUpdateSetting("Description", txtDescription.Text) q.Execute() This just updates all the rows in the table. I read in one post that instead of AddUpdateSetting, I should use AddWhere, but that didn't make any sense to me. I don't need a where clause at all. Searching for all:QueryType.Insert at subsonicproject.com didn't return anything (which I thought was weird). Can anyone tell me how to fix this query? Thanks!

• c#/.NET SQLite -- REINDEX not working?

  - by borg17of20

  Hello all, I'm trying to reindex a table in a simple database that I created using SQLite.NET and VS2008. I need to reindex tables after every DELETE command and here is the code snippet I have written (it does not work): SQLiteCommand currentCommand; String tempString = "REINDEX tf_questions"; //String tempString = "REINDEX [main].tf_questions"; //String tempString = "REINDEX main.tf_questions"; currentCommand = new SQLiteCommand(myConnection); currentCommand.CommandText = tempString; currentCommand.ExecuteNonQuery() When run within my program, the code produces no errors, but it also doesn't reindex the "tf_questions" table. In the above example, you will also see the other query strings I've tried that also don't work. Please help, Thanks

• Variable in one query is getting into another query in view

  - by Jason Shultz

  I have two foreach statements. The variable from one one is somehow getting into another and i'm not sure how to fix it. Here's my controller: // Categories Page Code function categories($id) { $this->load->model('Business_model'); $data['businessList'] = $this->Business_model->categoryPageList($id); $data['catList'] = $this->Business_model->categoryList(); $data['featured'] = $this->Business_model->frontPageList(); $data['user_id'] = $this->tank_auth->get_user_id(); $data['username'] = $this->tank_auth->get_username(); $data['page_title'] = 'Welcome To Jerome - Largest Ghost Town in America'; $data['page'] = 'category_view'; // pass the actual view to use as a parameter $this->load->view('container',$data); } What happens is categories will only show the businesses in a certain category. The businesses are pulled from the database using the categoryPageList($id) function. Here is that function: function categoryPageList($id) { $this->db->select('b.id, b.busname, b.busowner, b.webaddress, p.thumb, v.title, c.catname, s.specname, p.thumb, c.id'); $this->db->from ('business AS b'); $this->db->where('b.category', $id); $this->db->join('photos AS p', 'p.busid = b.id', 'left'); $this->db->join('video AS v', 'v.busid = b.id', 'left'); $this->db->join('specials AS s', 's.busid = b.id', 'left'); $this->db->join('category As c', 'b.category = c.id', 'left'); $this->db->group_by("b.id"); return $this->db->get(); } And here is the view: <h2>Welcome to Jerome, Arizona</h2> <p>Choose the Category of Business you are interested in:<br/> <?php foreach ($catList->result() as $row): ?> <a href="/site/categories/<?=$row->id?>"><?=$row->catname?></a>, &nbsp; <?php endforeach; ?></p> <table id="businessTable" class="tablesorter"> <thead><tr><th>Business Name</th><th>Business Owner</th><th>Web</th><th>Photos</th><th>Videos</th><th>Specials</th></tr></thead> <?php if(count($businessList) > 0) : foreach ($businessList->result() as $crow): ?> <tr> <td><a href="/site/business/<?=$crow->id?>"><?=$crow->busname?></a></td> <td><?=$crow->busowner?></td> <td><a href="<?=$crow->webaddress?>">Visit Site</a></td> <td> <?php if(isset($crow->thumb)):?> yes <?php else:?> no <?php endif?> </td> <td> <?php if(isset($crow->title)):?> yes <?php else:?> no <?php endif?> </td> <td> <?php if(isset($crow->specname)):?> yes <?php else:?> no <?php endif?> </td> </tr> <?php endforeach; ?> <?php else : ?> <td colspan="4"><p>No Category Selected</p></td> <?php endif; ?> </table> The problem occurs here. <?=$crow->id?> should be showing the row id from the business table. Instead, it's showing the row ID of the category table. so, if i'm viewing /site/categories/6 <?=$crow->id?> will show 6 when it should be showing 10 (the row ID of the only business in that category at this time. How can I fix this?

• Database design - alternatives for Entity Attribute Value (EAV)

  - by Bob

  Hi, see http://stackoverflow.com/questions/695752/product-table-many-kinds-of-product-each-product-has-many-parameters for similar topic. My question: i want to design a database, that will be used for a production facility of different types of products where each product has its own (number of) parameters. because i want the serial numbers to be in one tabel for overview purposes i have a problem with these different paraeters . One solution could be EAV, but it has its downsides, certainly because we have +- 5 products with every product +- 20.000 serial numbers (records). it looks a bit overkill to me... I just don't know how one could design a database so that you have an attribute in a mastertable that says: 'hey, you could find details of this record in THAT detail-table". 'in a way that you qould easely query the results) currenty i am using Visual Basic & Acces 2007. but i'm going to Visual Basic & MySQL. thanks for your help. Bob

• Time and date dimension in data warehouse

  - by peperg

  I'm buildind an data warehouse. Each fact has it's timestamp. I need to create reports by day, month, quater but by hours too. Loking at the examples I see that dates tend to be saved in dimension tabels. But I think, that it makes no sense for time. The dimension table would grow and grow. On the other hand JOIN with date dimension table is more efficent than using date/time functions in SQL. What are your opinions/solutions ? (I'm using Infobright)

• Does Entity Framework 4 not support property automatic lazy loading for model-first entities?

  - by KallDrexx

  All references that I find for lazy loading say it's possible but they all mention POCOs and that's it. I am using EF4 with the model-first methodology. In my model diagram I have a Project table and a UserObject table, with a 1 to many relationship between them. However, in code, when I have a valid UserObject and I attempt to get the project performing: Project prj = userobj.Project. Unfortunately, this doesn't work as it claims that UserObject.Project is null. It seems like I have to explicitly load the Project object via calling UserObject.ProjectReference.Load() prior to calling .Project. Is there any way for this to occur automatically when I access the .Project property?

• One to many too much data returned - MySQL

  - by Evan McPeters

  I have 2 related MySQL tables in a one to many relationship. Customers: cust_id, cust_name, cust_notes Orders: order_id, cust_id, order_comments So, if I do a standard join to get all customers and their orders via PHP, I return something like: Jack Black, jack's notes, comments about jack's 1st order Jack Black, jack's notes, comments about jack's 2nd order Simon Smith, simon's notes, comments about simon's 1st order Simon Smith, simon's notes, comments about simon's 2nd order The problem is that *cust_notes* is a text field and can be quite large (a couple of thousand words). So, it seems like returning that field for every order is inneficient. I could use *GROUP_CONCAT* and JOINS to return all *order_comments* on a single row BUT order_comments is a large text field too, so it seems like that could create a problem. Should I just use two separate queries, one for the customers table and one for the orders table? Is there a better way?

• Using MongoDB with Ruby On Rails and the Mongomapper plugin

  - by Micke

  Hello, i am currently trying to learn Ruby On Rails as i am a long-time PHP developer so i am building my own community like page. I have came pritty far and have made the user models and suchs using MySQL. But then i heard of MongoDB and looked in to it a little bit more and i find it kinda nice. So i have set it up and i am using mongomapper for the connection between rails and MongoDB. And i am now using it for the News page on the site. I also have a profile page for every User which includes their own guestbook so other users can come to their profile and write a little message to them. My thought now is to change the User models from using MySQL to start using MongoDB. I can start by showing how the models for each User is set up. The user model: class User < ActiveRecord::Base has_one :guestbook, :class_name => "User::Guestbook" The Guestbook model model: class User::Guestbook < ActiveRecord::Base belongs_to :user has_many :posts, :class_name => "User::Guestbook::Posts", :foreign_key => "user_id" And then the Guestbook posts model: class User::Guestbook::Posts < ActiveRecord::Base belongs_to :guestbook, :class_name => "User::Guestbook" I have divided it like this for my own convenience but now when i am going to try to migrate to MongoDB i dont know how to make the tables. I would like to have one table for each user and in that table a "column" for all the guestbook entries since MongoDB can have a EmbeddedDocument. I would like to do this so i just have one Table for each user and not like now when i have three tables just to be able to have a guestbook. So my thought is to have it like this: The user model: class User include MongoMapper::Document one :guestbook, :class_name => "User::Guestbook" The Guestbook model model: class User::Guestbook include MongoMapper::EmbeddedDocument belongs_to :user many :posts, :class_name => "User::Guestbook::Posts", :foreign_key => "user_id" And then the Guestbook posts model: class User::Guestbook::Posts include MongoMapper::EmbeddedDocument belongs_to :guestbook, :class_name => "User::Guestbook" But then i can think of one problem.. That when i just want to fetch the user information like a nickname and a birthdate then it will have to fetch all the users guestbook posts. And if each user has like a thousand posts in the guestbook it will get really much to fetch for the system. Or am i wrong? Do you think i should do it any other way? Thanks in advance and sorry if i am hard to understand but i am not so educated in the english language :)

• Best way to display a list of events by month

  - by EmmyS

  I have a mySQL table of events and want to display them in a list using PHP. Pretty simple, except I only want to display the month name once, for example: May 2010 12th, 7 pm. Event 1 - event one description 15th, 5:30 pm. Event 2 - event two description June 2010 9th, 7 pm. Event 1 - event one description 11th, 5:30 pm. Event 2 - event two description I'm very new at SQL and PHP. I can think of one way to do it. It would involve selecting all records grouped by date, then looping through all records, comparing the month/year value each time and the first time the month/year doesn't match, print a new header row to my HTML table. I can't believe it's the best or most efficient way to go. Any ideas for a newbie? I'm sure my way would work, but it's inelegant at best, and processor-intensive at worst.

• Charater string buffer too small

  I have select: select v.accs, v.currency,v.amount,v.drcr_ind, count(*) qua,wm_concat(ids) npx_IDS, wm_concat(px_dtct) npx_DTCT from table v group by accs, currency, amount, drcr_ind but i get error ORA-06502: PL/SQL: : character string buffer too small if i'll remove one string, because sometimes (when v.accs= 3570) count(*) = 215 but when i try to skip using wm_concat for v.accs= 3570 for example this way: select v.accs, v.currency,v.amount,v.drcr_ind, count(*) qua,wm_concat(ids) npx_IDS, (case when v.accs = 3570 then wm_concat(px_dtct) else 'too many' end) npx_DTCT from table v group by accs, currency, amount, drcr_ind i still have the same error message. But why? How can i fix it? Thanx

• Excel and Tab Delimited Files Question

  - by OneNerd

  I am encountering what I believe to be a strange issue with Excel (in this case, Excel 2007, but maybe also Excel 2003, but don't have access to it as I write this). I can reliably convert some server data over into a tab-delimited format (been doing this for years) and then open it using Excel - no issue. However, what seems to be happening is if I have an html <table inside one of the fields, it looks like Excel 2007 thinks it should be converting the table into rows and columns inside Excel (not what I want). As you might imagine, this throws off the entire spreadsheet. So question is, is there any way to set up excel to NOT do this (perhaps some setting in Excel that pertains to reading tab delimited files), or am I missing something? Thanks.

• getting rid of filesort on WordPress MySQL query

  - by Hans

  An instance of WordPress that I manage goes down about once a day due to this monster MySQL query taking far too long: SELECT SQL_CALC_FOUND_ROWS distinct wp_posts.* FROM wp_posts LEFT JOIN wp_term_relationships ON (wp_posts.ID = wp_term_relationships.object_id) LEFT JOIN wp_term_taxonomy ON wp_term_taxonomy.term_taxonomy_id = wp_term_relationships.term_taxonomy_id LEFT JOIN wp_ec3_schedule ec3_sch ON ec3_sch.post_id=id WHERE 1=1 AND wp_posts.ID NOT IN ( SELECT tr.object_id FROM wp_term_relationships AS tr INNER JOIN wp_term_taxonomy AS tt ON tr.term_taxonomy_id = tt.term_taxonomy_id WHERE tt.taxonomy = 'category' AND tt.term_id IN ('1050') ) AND wp_posts.post_type = 'post' AND (wp_posts.post_status = 'publish') AND NOT EXISTS (SELECT * FROM wp_term_relationships JOIN wp_term_taxonomy ON wp_term_taxonomy.term_taxonomy_id = wp_term_relationships.term_taxonomy_id WHERE wp_term_relationships.object_id = wp_posts.ID AND wp_term_taxonomy.taxonomy = 'category' AND wp_term_taxonomy.term_id IN (533,3567) ) AND ec3_sch.post_id IS NULL GROUP BY wp_posts.ID ORDER BY wp_posts.post_date DESC LIMIT 0, 10; What do I have to do to get rid of the very slow filesort?

• Querying for names

  - by Sai

  I have a table (say "Demographics") on SQL Server. In this table are the following columns "LastName", "FirstName", "MiddleName", "Prefix" , "Suffix". I have one textbox to search for them on a webpage. My question: Whats a good design strategy for queries where the user could be searching for various combinations of names including last names that have spaces e.g. "Smith James Jr." . Our customers store Jr. sometimes in suffix and sometimes just tack it to lastname. Sometimes Smith James Jr could be the entire last name.

• Hibernate list operation question

  - by Sumit Kishore

  I'm working on a utility to update a list of entities in a database as a group. The database contains a list of entities. The result of the update is a new list. The API accepts this new list. The update may end up modifying some of the entities in the list, creating new ones and deleting some. So at the entity level, I may have to do any of an insert, delete or update operation. But it's always true that the final list in the database will be the same as the list passed down to the API. Is there in Hibernate a way to treat this operation at the list level, that is, tell Hibernate to persist this list of entities, and let it take care of which need to be created, updated or deleted? There is no entity/table representing this list, btw. Just the entities themselves in a table.

• UpdatePanel, Repeater, DataBinding Problem

  - by Gordon Carpenter-Thompson

  In a user control, I've got a Repeater inside of an UpdatePanel (which id displayed inside of a ModalPopupExtender. The Repeater is databound using an array list of MyDTO objects. There are two buttons for each Item in the list. Upon binding the ImageURL and CommandArgument are set. This code works fine the first time around but the CommandArgument is wrong thereafter. It seems like the display is updated correctly but the DTO isn't and the CommandArgument sent is the one that has just been removed. Can anybody spot any problems with the code?

• How to display and update data in MVC2

  - by Picflight

  Table Product Product Id Product Name Table ProductSupplier ProductSupplierId ProductId SupplierId Table Supplier SupplierId SupplierName I have the above 3 tables in my database, ProductSupplier is the lookup table. Each Product can have many suppliers. I am using Entity Framework. Using Web Forms it was fairly easy to display a Product on a web page and bind a repeater with the suppliers information. Also, with Web Forms it was easy to Add new Product and suppliers, the linkage seemed easy. How do you do this sort of functionality in MVC? In the Create View below, I want to be able to Add the Supplier as well. Is there a better approach that I might be missing here? This is how I did it with Web Forms. Beyond the code below I am totally lost. I can show data in a list and also display the Suppliers for each Product, but how do I Add and Edit. Should I break it into different views? With Web Forms I could do it all in one page. namespace MyProject.Mvc.Models { [MetadataType(typeof(ProductMetaData))] public partial class Product { public Product() { // Initialize Product this.CreateDate = System.DateTime.Now; } } public class ProductMetaData { [Required(ErrorMessage = "Product name is required")] [StringLength(50, ErrorMessage = "Product name must be under 50 characters")] public object ProductName { get; set; } [Required(ErrorMessage = "Description is required")] public object Description { get; set; } } public class ProductFormViewModel { public Product Product { get; private set; } public IEnumerable<ProductSupplier> ProductSupplier { get; private set; } public ProductFormViewModel() { Product = new Product(); } public ProductFormViewModel(Product product) { Product = product; ProductSupplier = product.ProductSupplier; } } } ProductRepository public Product GetProduct(int id) { var p = db.Product.FirstOrDefault(por => por.ProductId == id); p.ProductSupplier.Attach(p.ProductSupplier.CreateSourceQuery().Include("Product").ToList()); return p; } Product Create View <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<MyProject.Mvc.Models.ProductFormViewModel>" %> <%= Html.ValidationSummary("Please correct the errors and try again.") %> <% using (Html.BeginForm()) {%> <fieldset> <legend>Fields</legend> <div class="editor-label"> <%= Html.LabelFor(model => model.Product.ProductId) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Product.ProductId) %> <%= Html.ValidationMessageFor(model => model.Product.ProductId) %> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.Product.ProductName) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Product.ProductName) %> <%= Html.ValidationMessageFor(model => model.Product.ProductName) %> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.Product.Description) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Product.Description) %> <%= Html.ValidationMessageFor(model => model.Product.Description) %> </div> <p> <input type="submit" value="Create" /> </p> </fieldset> <% } %>

• Slow select when inserting large amounts of data (MYSQL)

  - by siannopollo

  I have a process that imports a lot of data (950k rows) using inserts that insert 500 rows at a time. The process generally takes about 12 hours, which isn't too bad. Normally doing a query on the table is pretty quick (under 1 second) as I've put (what I think to be) the proper indexes in place. The problem I'm having is trying to run a query when the import process is running. It is making the query take almost 2 minutes! What can I do to make these two things not compete for resources (or whatever)? I've looked into "insert delayed" but not sure I want to change the table to MyISAM. Thanks for any help!

• FullText Search using multiple tables in SQL

  - by Caesar

  Hi there. I have 3 tables, tblBook(BookID, ISBN, Title, Summary) tblAuthor(AuthorID, FullName) tblBookAuthor(BookAuthorID, BookID, AuthorID) tblBookAuthor allows for a single book to have multiple authors and an author may have written any number of books. I am using full text search to search for ranking base on a word: SET @Word = 'FORMSOF(INFLECTIONAL, "' + @Word + '")' SELECT COALESCE(ISBNResults.[KEY], TitleResults.[KEY], SummaryResults.[KEY]) AS [KEY], ISNULL(ISBNResults.Rank, 0) * 3 + ISNULL(TitleResults.Rank, 0) * 2 + ISNULL(SummaryResults.Rank, 0) AS Rank FROM CONTAINSTABLE(tblBook, ISBN, @Word, LANGUAGE 'English') AS ISBNResults FULL OUTER JOIN CONTAINSTABLE(tblBook, Title, @Word, LANGUAGE 'English') AS TitleResults ON ISBNResults.[KEY] = TitleResults.[KEY] FULL OUTER JOIN CONTAINSTABLE(tblBook, Summary, @Word, LANGUAGE 'English') AS SummaryResults ON ISBNResults.[KEY] = SummaryResults.[KEY] The above code works fine for just searching tblBook table. But now I would like to search also the table tblAuthor based on key word searched. Can you help me with this?
