• Problem exporting SQL Server management Studio Express to Go Daddy

  - by brohjoe

  I'm having a terrible time exporting SQL Server Management Studio Express tables to the Go Daddy webserver. Go Daddy support can't help either. I started by using Microsoft Database Publishing Wizard for SQL Server thinking it would be 'easy'....not! I ran into user/password errors even though I was using the user and password that was created for the SQL database in the Go Daddy site. I called help desk support at Go Daddy and went through several iterations of processes to get the thing working but it didn't. Finally, the support guy acted like his phone went on the blip and scuttled away. There has got to be someway to upload SQL Server to a webserver without a lot of drama. Any suggestions?

• Variable height header with scrollable content area filling remaining viewport area

  - by Neutrino

  I've seen versions of this simple problem raised a dozen times here and elsewhere on the web, but I haven't seen a solution that works for me yet so I'm asking it again. I want a webpage with a variable height full width header (height based on contents). Below that I want a content area that fills the rest of the browser viewport. If the content is larger than the remaining space in the viewport then I want the content area to scroll. I don't need this to work on IE6. I don't care whether the solution uses CSS, tables or a mixture of the two, just no frames and no Javascript. For a bonus point fix a variable height footer to the bottom of the page.

• PostgreSQL 8.3 data types: xml vs varchar

  - by Sejanus

  There's xml data type in Postgres, I never used it before so I'd like to hear opinions. Downsides and upsides vs using regular varchar (or Text) column to store xml. The text I'm going to store is xml, well-formed, UTF-8. No need to search by it (I've read searching by xml is slow). This XML actually is data prepared for PDF generation with Apache FOP. XML can be generated dynamically from data found elsewhere (other Postgres tables), it's stored as is only so that I won't need to generate it twice. Kinda backup#2 for already generated PDF documents. Anything else to know? Good practices, performance, maintenance, etc?

• Dynamically Adding Multiple User Controls vb.net

  - by Jamie Hartnoll

  I have a User Control which returns a table of data, which in some cases needs to be looped, displaying one on top of another. I am able to dynamically add a single instance of this by placing a fixed placeholder in the page. I am now trying to work out how to add more than one, given that I don't know how many might be needed I don't want to hard code the Placeholders. I've tried the following, but I am just getting one instance, presumably the first is being overwritten by the second My HTML <div id="showHere" runt="server"/> VB Dim thisPh As New PlaceHolder thisPh.Controls.Add(showTable) showHere.Controls.Add(thisPh) Dim anotherPh As New PlaceHolder anotherPh .Controls.Add(showTable) showHere.Controls.Add(anotherPh) How do I make it add repeated tables within the showHere div?

• many-to-many query

  - by kofto4ka

  Hello, guys! I have a problem and I dont know what is better solution. Okay, I have 2 tables: posts(id, title), posts_tags(post_id, tag_id). I have next task: must select posts with tags ids for example 4, 10 and 11. Not exactly, post could have any other tags at the same time. So, how I could do it more optimized? Creating temporary table in each query? Or may be some kind of stored procedure? In the future, user could ask script to select posts with any count of tags (it could be 1 tag only or 10 at the same time) and I must be sure that method that I will choose would be the best method for my problem. Sorry for my english, thx for attention.

• Entity Framework v4 examples and tutorials of conceptual model mapping

  - by Rody van Sambeek

  In an application I'm writing I have a fairly complicated Database model. I'd like to use EF4 to map this to a whole lot nicer conceptual model. However all the tutorials I've read are with samples of 2 or 3 tables which all map 1 on 1 to the conceptual model. I'd like to learn how to correctly map the database model to a different conceptual model using VS 2010. However I can't find any good tutorials or (preferabally) instruction video's. Somebody got any tips, links or even books?

• PrincipalPermission - roles seperate from permissions

  - by Leblanc Meneses

  I've been using PrincipalPermission for a while in wcf services. [PrincipalPermission(SecurityAction.Demand, Role = SecurityRoles.CanManageUsers)] although now i have a requirement to simplify roles by business unit. - currently aspnet_roles has fine grained can* permissions. Here is my approach and wanted to see if anyone can provide feedback, code review before i implement my suggestion. 1) aspnet_roles - business unit role 2) create permission table and Role_Permission table and User_Permission table (many to many) 3) create custom CodeAccessSecurityAttribute + that looks at new tables [CustomPermissionCheck(Security.Demand, HasPermission="can*")] first iteration i'll statically new the dependent repository.. ideally i would like an aop style attribute that has repository injected IPermissionRepository.HasPermission(...); If i approach new aop way i probably will stop inheriting from CodeAccessSecurityAttribute -- what do the security guys have to say about this? has anyone else solved this, is there something in the framework that i've missed?

• Access - how to derive a field upon entry of a record

  - by jonos

  I have an Access database for a media rental company which includes the following tables, among others; LOAN: customer_id (pk), loan_datetimeLeant (pk), loan_dateReturned (pk) LOAN_ITEMS: customer_id (pk), loan_datetimeLeant (pk), item_id (pk), loanItem_cost ITEM: item_id (pk), product_id, item_availability PRODUCT: product_id (pk), product_name, product_type MEDIA_COST: product_type (pk), product_cost So basically the 'product type' (DVD, VHS etc) determines the cost. The 'product id' determines what movie, platform etc each item is. My question is: When creating a form for the Loan_Items table, how can I populate the loanItem_cost field (so it is stored) whenever a new Loan_Item record is added? I need to store it as the cost of the item (product_cost) may change over time and I'd like to record what the customer paid at the time the loan was made. Thanks in advance

• Is there a difference SMO ServerConnection transaction methods versus using the SqlConnectionObject

  - by YWE

  I am using SMO to create databases and tables on a SQL Server. I want to do so in a transaction. Are both of these methods of doing so valid and equivalent: First method: Server server; //... server.ConnectionContext.BeginTransaction(); //... server.ConnectionContext.CommitTransaction(); Second method: Server server; // ... SqlConnection conn = server.ConnectionContext.SqlConnectionObject; SqlTransaction trans = conn.BeginTransaction(); // ... trans.Commit();

• A way to avoid deriving from the provider classes in mvc authentication

  - by Shymep

  Looking for the best practice for authentication in MVC I unfortunately didn't find the clear answer to my question. Thinking of the problem I tried to imagine some priciples that could be useful in my design. Well, I would like to use a base AccountController class I want to place all the tables such as "Users", Roles, Rights etc into my own database. But I wouldn't like to implement the standard aspnetdb design (which can be easy got by using aspnet_regsql) So the main question is can I do this without deriving abstract classes like MembershipProvider, RoleProvider etc? What I would prefer not to do is implement all the abstract methods from these classes. The second question is still about the best practice for authentication e.g. for the small projects, for the large ones?

• Hibernate generate POJOs with Equals

  - by jschoen

  We are using hibernate in a new project where we use the hibernate.reveng.xml to create our *.hbm.xml files and POJOs after that. We want to have equals methods in each of our POJOs. I found that you can use <meta attribute="use-in-equals">true</meta> in your hbm files to mark which properties to use in the equals. But this would mean editing alot of files, and then re-editing the files again in the future if/when we modify tables or columns in our DB. So I was wondering if there is a way to place which properties to use in the equals method for each pojo(table) in the hibernate.reveng.xml file?

• Problem with HSQLDB & SequenceGenerator

  - by Srirangan

  Hi, I have an entity which has an ID field: @Id @Column(name = "`U##ID_VOIE`") @GeneratedValue(generator = "VOIE_SEQ") private String id; The class has the sequence generator defined as well: @SequenceGenerator(name = "VOIE_SEQ", sequenceName = "VOIE_SEQ") and the Oracle schema has the requisite sequence present. Everything works okay. We also have tests, which uses an in-memory HSQLDB. Before running the tests, all the tables are created based on the Hibernate entity classes. However the table for this particular class is not being created. And error pops up, because ID is a String and the SequenceGenerator in HSQLDB returns an INT / LONG / Numeric value. The application is using a legacy Oracle database and ID_VOIE column must remain a String / Varchar. Any solutions?

• select random value from each type

  - by Joseph Mastey

  I have two tables, rating: +-----------+-----------+-------------+----------+ | rating_id | entity_id | rating_code | position | +-----------+-----------+-------------+----------+ | 1 | 1 | Quality | 0 | | 2 | 1 | Value | 0 | | 3 | 1 | Price | 0 | +-----------+-----------+-------------+----------+ And rating_option +-----------+-----------+------+-------+----------+ | option_id | rating_id | code | value | position | +-----------+-----------+------+-------+----------+ | 1 | 1 | 1 | 1 | 1 | | 2 | 1 | 2 | 2 | 2 | | 3 | 1 | 3 | 3 | 3 | | 4 | 1 | 4 | 4 | 4 | | 5 | 1 | 5 | 5 | 5 | | 6 | 2 | 1 | 1 | 1 | | 7 | 2 | 2 | 2 | 2 | | 8 | 2 | 3 | 3 | 3 | | 9 | 2 | 4 | 4 | 4 | | 10 | 2 | 5 | 5 | 5 | | 11 | 3 | 1 | 1 | 1 | | 12 | 3 | 2 | 2 | 2 | | 13 | 3 | 3 | 3 | 3 | | 14 | 3 | 4 | 4 | 4 | | 15 | 3 | 5 | 5 | 5 | +-----------+-----------+------+-------+----------+ I need a SQL query (not application level, must stay in the database) which will select a set of ratings randomly. A sample result would look like this, but would pick a random value for each rating_id on subsequent calls: +-----------+-----------+------+-------+----------+ | option_id | rating_id | code | value | position | +-----------+-----------+------+-------+----------+ | 1 | 1 | 1 | 1 | 1 | | 8 | 2 | 3 | 3 | 3 | | 15 | 3 | 5 | 5 | 5 | +-----------+-----------+------+-------+----------+ I'm totally stuck on the random part, and grouping by rating_id has been a crap shoot so far. Any MySQL ninjas want to take a stab? Thanks, Joe

• Thoughts/Input about Database Design for a CMS

  - by dallasclark

  I'm just about to expand the functionality of our own CMS but was thinking of restructuring the database to make it simpler to add/edit data types and values. Currently, the CMS is quite flat - the CMS requires a field in the database for every type of stored value (manually created). The first option that comes to mind is simply a table which keeps the data types (ie: Address 1, Suburb, Email Address etc) and another table which holds values for each of these data types. Just like how Wordpress keeps values in the 'options' table, PHP serialize would be used to store an array of values. The second option is how Drupal works, the CMS creates tables for every data type. Unlike Wordpress, this can be a bit of an overkill but really useful for SQL queries when ordering and grouping by a particular value. What's everyone's thoughts?

• Saving data to server with user accounts.

  - by AKRamkumar

  Ok, so for an app I am making, I want the user to be able to save data online. On my website, I will provide a web server with tables of UserName/Password/SaveData. How can I do this without crashing the server load? How can I guarantee security ? Is there a Design Pattern for this?Is there a better way of doing this? This is going to be a free application, available to the public and I would like for their settings to be available, no matter the computer they are using. Is there a better way of doing this? I am using MEF for plugins so is there a way I can save plugin data as well?

• How to perform a many-to-many Linq query with Include in the EF.

  - by despart

  Hi, I don't know how to perform this query using Linq and the EF. Imagine I have three tables A, B and C. A and B have a many-to-many relationship. B and C have a 1-to-many relationship. I want to obtain records from B including C but filtering from A's Id. I can get easily the records from B: var b = Context.A.Where(x => x.Id.Equals(aId)).SelectMany(x => x.B); but when I try to include C I don't know how to do it: //This doesn't work var b = Context.A.Where(x => x.Id.Equals(aId)).SelectMany(x => x.B.Include("C")); Also I've tried this with no luck (it is equivalent to the above): //Not working var b = (from a in Context.A.Where(x => x.Id.Equals(aId)) from b in a.B.Include("C") select b); Thanks for your help.

• SQLite.Net Issue With BeginTransaction

  - by cam

  I'm trying to use System.Data.Sqlite library, and I'm following the documentation about optimizing inserts so I copied this code directly out of the documentation: using (SQLiteTransaction mytransaction = myconnection.BeginTransaction()) { using (SQLiteCommand mycommand = new SQLiteCommand(myconnection)) { SQLiteParameter myparam = new SQLiteParameter(); int n; mycommand.CommandText = "INSERT INTO [MyTable] ([MyId]) VALUES(?)"; mycommand.Parameters.Add(myparam); for (n = 0; n < 100000; n ++) { myparam.Value = n + 1; mycommand.ExecuteNonQuery(); } } mytransaction.Commit(); } Now, I initialize I connection right before that by using SqlConnection myconnection = new SqlConnection("Data Source=blah"); I have a Database named blah, with the correct tables and values. The problem is when I run this code, it says "Operation is not valid due to the current state of the object" I've tried changing the code around several times, and it still points to BeginTransaction. What gives?

• How to assign default values and define unique keys in Entity Framework 4 Designer

  - by csharpnoob

  Hello, I've had a look at the Entity Framework 4. While generating code for the SQL Server 2008 I came to the point where I want to define some default values for some fields. how to define in the designer for a Created DateTime Field the DateTime.Now default value? - Error 54: Default value (DateTime.Now) is not valid for DateTime. The value must be in the form 'yyyy-MM-dd HH:mm:ss.fffZ' how to make for code generation a string Field unique. Like E-Mail or Username can exists only once in the table. I've search alot in the internet and also checked my books Pro Entity Framework 4.0 and Programming Entity Framework. But none of them seems to come up with the default value issue, or using sql commands as default values for database generation. Another thing is, how to prevent on database generation always from droping tables? Instead i want to append non existing fields and keep the data. Thanks for any suggestions.

• Help with SQL query (list strings and count in same query)

  - by Mestika

  Hi everybody, I’m working on a small kind of log system to a webpage, and I’m having some difficulties with a query I want to do multiple things. I have tried to do some nested / subqueries but can’t seem to get it right. I’ve two tables: User = {userid: int, username} Registered = {userid: int, favoriteid: int} What I need is a query to list all the userid’s and the usernames of each user. In addition, I also need to count the total number of favoriteid’s the user is registered with. A user who is not registered for any favorite must also be listed, but with the favorite count shown as zero. I hope that I have explained my request probably but otherwise please write back so I can elaborate. By the way, the query I’ve tried with look like this: SELECT user.userid, user.username FROM user,registered WHERE user.userid = registered.userid(SELECT COUNT(favoriteid) FROM registered) However, it doesn’t do the trick, unfortunately Kind regards Mestika

I have to omit specifying columns which should be displayed under select statement. I would like to use there a *. I red that other sql-s have something like natural join and that is probably (or not?) an answer for my question. Unfortunately there is no join like that in SQL Server (2005). Do anybody knows any good replacement of it?

• Changing content of HTMLDocument displayed in a JTextPane

  - by kayahr

  I'm displaying some tables as HTML code (rendered by a Freemarker template) with a JTextPane. I also have some HTML links in this HTML output which can be used to interact with the values of the table (For example "Delete a row" and stuff like this). Currently I always recreate the whole HTML output on each change and replace the whole document in the JTextPane with the new one. This is getting really slow and the JTextPane always changes the scroll position when I do this. Is it possible to change only parts of the HTML code during runtime without replacing the whole document? In a real browser I would use the DOM and do something like document.getElementById("price").innerHTML = "$123.44". Is something like that possible with the HTMLDocument in a JTextPane?

• Hibernate and stored procedures

  - by cc96ai

  As my understanding on setting hibernate, I need to create table meta data file (person.hbm.xml), include all the fields mapping java object (person.java) If we use stored procedures for all transaction, do we still need the above configuration? It seems hibernate and stored procedures will overlap, We set up the stored procedure because we don't want the to developer know all the field in db. If tables change, then we need update above files. Does it mean if we purely use stored procedure, we should just go for JDBC? If hibernate, we should stay in HQL?

• C# Threading vs single thread

  - by user177883

  Is it always guaranteed that a multi-threaded application would run faster than a single threaded application? I have two threads that populates data from a data source but different entities (eg: database, from two different tables), seems like single threaded version of the application is running faster than the version with two threads. Why would the reason be? when i look at the performance monitor, both cpu s are very spikey ? is this due to context switching? what are the best practices to jack the CPU and fully utilize it? I hope this is not ambiguous.
