• Problem with filling dataset

  - by Brian

  This is a small portion of my code file. Each time my debugger reaches the line 'NewDA.Fill(NewDS);' at runtime it jumps to the catch. I'm positive the daynumber variable gets a value that's present in the database and I've tried the query outside of the codefile on my database and it works fine. I'm also using the connectionstring 'db' on more parts of the code with successful results. string QueryNew = "SELECT activityname AS [Name], activitycategorynumber AS [Category] " + "FROM ACTIVITY WHERE daynumber = @daynumber"; SqlCommand NewCmd = new SqlCommand(QueryNew, db); NewCmd.Parameters.Add("@daynumber", SqlDbType.Int).Value = daynumber; SqlDataAdapter NewDA = new SqlDataAdapter(NewCmd); DataSet NewDS = new DataSet(); NewDA.Fill(NewDS);

• Oracle 10g - Best way to escape single quotes

  - by satynos

  I have to generate some update statements based off a table in our database. I created the following script which is generating the update statements I need. But when I try to run those scripts I am getting errors pertaining to unescaped single quotes in the content and &B, &T characters which have special meaning in oracle. I took care of the &B and &T problem by setting SET DEFINE OFF. Whats the best way to escape single quotes within the content? DECLARE CURSOR C1 IS SELECT * FROM EMPLOYEES; BEGIN FOR I IN C1 LOOP DBMS_OUTPUT.PUT_LINE('UPDATE EMPLOYEES SET FIRST_NAME= ''' || I.FIRST_NAME|| ''', LAST_NAME = ''' || I.LAST_NAME ''', DOB = ''' || I.DOB|| ''' WHERE EMPLOYEE_ID = ''' || I.EMPLOYEE_ID || ''';'); END LOOP; END; Here if the first_name or last_name contains single quotes then the generated update statements break. Whats the best way to escape those single quotes within the first_name and last_name?

• Is it really wrong to version documents using CouchDB's default behaviour?

  - by Tomas Sedovic

  This is one of those "I know I shouldn't do this but it's oh so convenient." questions. Sorry about that. I plan to use CouchDB for storing a bunch of documents and keeping their entire revision history. CouchDB does the versioning automatically, but it is strongly discouraged for programmer's use: "You cannot rely on document revisions for any other purpose than concurrency control." From what I've found on the CouchDB wiki, the versions can get deleted either during compaction or during replication. As far as I can tell, Compaction must always be triggered manually and Replication occurs only when there's more than one database server. The question is: if I won't run compaction and will use only single database instance for my documents, can I just use CouchDB's document versioning and expect it to work? What other problems I might run into? E.g. does not running compaction hurt the performance or consume significantly more disk space (than if I did handle the versioning manually)?

• SQLite multi process access

  - by Nicolas

  Hello, We are using SQLite in a multi processes and multi threaded application. The SQLite database files are encrypted using the embedded SQLite encryption. The FAQ states that SQLite should be able to manage multi process accesses using locks mechanism. We are experiencing a strange problem: When many threads are accessing the same database file, sometime constrains violations occur, more specifically - a field with a unique constrain is getting duplicate values after calling "insert or replace" statement. It happens quite often now, that we are using the encryption. Before we started using SQLite encryption we did not notice such a behavior. Are there any specific known issues with this?

• Disk-based caching of dynamic images in IIS 7

  - by Daniel Schierbeck

  I'm writing an image server which needs to handle a relatively large number of concurrent requests (~5,000). The images being served are dynamically scaled down and cropped based on per-image specifications, which are queried from a database. The number of images is rather large, so an in-memory cache isn't viable (thrashing would most definitely occur). I'm using native caching in IIS 7 to avoid hitting the ASP.NET app which generates the images on-the-fly. I've looked around, but I couldn't find a simple way to configure IIS to store the cache on-disk -- is there such an option, or would I need to roll my own? I'd rather avoid placing the generated images in a public folder, so they can be served statically, since I would prefer to invalidate the cache entries using a query parameter (last-edit time from the database,) which doesn't seem possible to reconcile with static caching. I would love to get some feedback on this!

• How difficult is it to migrate away from Google App Engine?

  - by Ignas Limanauskas

  I am thinking of making an (initially) small Web Application, which would eventually have a potential to grow. All things considered Google App Engine seems like a very attractive option. Say, user base and complexity grows and for one or other reason I needed to leave GAE behind. How difficult would it be to migrate away? 1) Does GAE provide a way to export the database? What format would it be? Would it be difficult to put it under MySQL (or similar)? 2) In which areas (ex. database access, others?) would I have to use GAE API? I.e. which parts of implementation would have to be abstracted away / interfaced? 3) Alternatively, is it even worth to keep GAE API outside, say, if there is nothing much I would need to use.

• Checkbox 'Checked' in ListView is restored after scrolling

  - by adrianrdzv

  I'm having the following problem: I have a ListActivity, which its ListView is composed by an icon, text and a checkbox (using LayoutInflater). The Adapter for the ListView extends ResourceCursorAdapter (i.e. the data source of the ListView is retrieved from a database, also the Checked status of each row) Everything works pretty Ok, except when I uncheck/check the checkbox in any row, if I scroll down until the modified checkbox is no longer visible, and then scroll up, the checkbox is restored to its original state. The database IS modified, this is not the problem (i.e. if I modify a row and exit the activity, and enter again, the modified row is displayed Ok). My guess is that this has something to do on how the list is rendered because for some reason the ListView "renders" the original state of all rows when it was first populated when scrolling. I've been looking around for this bug but I don't find anybody that had this problem. I appreciate any advice you have.

• How to keep history of record updates in MySQL?

  - by Proxium

  I have to create a code in PHP that will allow me to keep the history of record updates in MySQL database so I can find by date an old revision. Here is the example of what I actualy want to achive: http://en.wikipedia.org/w/index.php?title=Tunisia&action=history The data are mostly Numbers that we record about the company for generating reports and to extract indices. I plan to use codeigniter for it's simplicity and I'm looking for idea about a framework or an opensource project that use the same approche to keep history of modifications in the database.

• Symfony 1.4: use relations in fixtures with propel

  - by iggnition

  Hello, I just started to use the PHP symfony framework. Currently I'm trying to create fixture files in YAML to easily insert data into my MySQL database. Now my database has a couple of relations, I have the tables Organisation and Location. Organisation org_id (PK) org_name Location loc_id (PK) org_id (FK) loc_name Now I'm trying too link these tables in my fixture file, but for the life of me I cannot figure out how. Since the org_id is auto-incremented I can't simply use org_id: 1 In the location fixture. How can I fix this?

• Using set with values from a table

  - by gozzilli

  I'm writing a database of all DVDs I have at home. One of the fields, actors, I would like it to be a set of values from an other table, which is storing actors. So for every film I want to store a list of actors, all of which selected from a list of actors, taken from a different table. Is it possible? How do I do this? It would be a set of foreign keys basically. I'm using a MySQL database for a Django application (python), so any hint in SQL or Python would be much appreciated. I hope the question is clear, many thanks.

• How to clean sys.conversation_endpoints

  - by Manjoor

  I have a table, a trigger on the table implemented using service broker. More than Half million records are inserted daily into the table. The asynchronous SP is used to check sveral condition by using inserted data and update other tables. It was running fine for last 1 month and the SP was get executed withing 2-3 seconds of insertion of record. But now it take more than 90 minute. At present sys.conversation_endpoints have too much records. (Note that all the table are truncated daily as I do not need those records day after) Other database activities are normal (average 60% CPU Utilization). Now where i need to look?? I can re-create database without any problem but i don't think it is a good way to resolve the problem

• Get list of named queries in NHibernate

  - by Dan

  I have a dozen or so named queries in my NHibernate project and I want to execute them against a test database in unit tests to make sure the syntax still matches the changing domain/database model. Currently I have a unit test for each named query where I get and execute the query, for example: IQuery query = session.GetNamedQuery("GetPersonSummaries"); var personSummaryArray = query.List(); Assert.That(personSummaryArray, Is.Not.Null); This works fine, but I would like to have one unit test that loops thru all of the named queries and executes them. Is there a way to discover all of the available named queries? Thanks Dan

• What is the correct way to unit test areas around exceptions

  - by Codek

  Hi, Looking at our code coverage of our unit tests we're quite high. But the last few % is tricky because a lot of them are catching things like database exceptions - which in normal circumstances just dont happen. For example the code prevents fields being too long etc, so the only possible database exceptions are if the DB is broken/down, or if the schema is changed under our feet. So is the only way to Mock the objects such that the exception can be thrown? That seems a little bit pointless. Perhaps it's better to just accept not getting 100% code coverage? Thanks, Dan

• Code editor with autocomplete

  - by Andrey

  I need to create a code editor for my own simple language: className.MethodName(parameterName = 2, ... ) I've created the appropriate grammar and autogenerate parser using ANTLR tool. Now I would like to have an autocomplete for class, method, variables and parameter names. This list should be context dependent, f.e. for "class." it should display methods and for "class.Method(" - parameters. I was going to parse the text and display the list depending on in which node the cursor is. The problem is that for incomplete code like "aaa.bbb(" the parser produces an error instead of a syntax tree. Any idea how to solve this problem? Maybe I'm on the wrong way and I shouldn't parse code to display autocomplete?

• Choosing the right .NET architecture. WCF? WPF/Forms, ASP.NET (MVC)?

  - by Tommy Jakobsen

  I’m in the situation that I have to design and implement a rather big system from the bottom. I’m having some (a lot actually) questions about the architecture that I would like your comments and thoughts on. I don’t hope that I’ve written too much here, but I wanted to give you all an idea of what the system is. Quick info about the applications, read if you want: I can’t share much detail about the project, but basically it’s a system where we offer our customer a service to manage their users. We have a hotline where the users call and our hotline uses an (windows) application (intranet) to manage the user’s data, etc. The customer also has a web application where they can see reports, information about their business and users, and the ability to modify their data. Modifying data is not just user data like address and so, but also information about the products/services the user has, which can be complicated. The applications will be built on Microsoft .NET Framework 4, with a MS SQL Server 2008 database. There will be a few applications that have to access this database, such as: Intranet application (used by us and our hotline) Customer web application type 1 Customer web application type 2 Customer web application type n different applications) … Now my big problem is what .NET parts I should use for such a system. For the “backend” I’ve considered using Windows Communication Foundation: Would WCF be a good choice? The intranet application will be an application that has to edit lots of records in the database. It has to be easy to navigate using the keyboard (fast to work with). Has a feature such as “find customer, find that, lookup this, choose this and update that”. What would be the best choice to develop this application in? Would it be WPF or good old Windows Forms? I don’t need all of the fancy graphics features in WPF, like 3D, but the application has to look nice (maybe something like the new Visual Studio/Office tools). And the same question goes for the web pages. They have much the same work to do, but not as many features as the intranet application, and not the same amount of data (much less). That is my questions for now. I’m hoping to get a discussion going that will open my eyes to some of these technologies, helping me decide architecture to go with. I would like to say thanks in advance, and let you all know that any thoughts will be much appreciated.

• Entity Framework: Data Centric vs. Object Centric

  - by Eric J.

  I'm having a look at Entity Framework and everything I'm reading takes a data centric approach to explaining EF. By that I mean that the fundamental relationships of the system are first defined in the database and objects are generated that reflect those relationships. Examples Quickstart (Entity Framework) Using Entity Framework entities as business objects? The EF documentation implies that it's not necessary to start from the database layer, e.g. Developers can work with a consistent application object model that can be mapped to various storage schemas When designing a new system (simplified version), I tend to first create a class model, then generate business objects from the model, code business layer stuff that can't be generated, and then worry about persistence (or rather work with a DBA and let him worry about the most efficient persistence strategy). That object centric approach is well supported by ORM technologies such as (n)Hibernate. Is there a reasonable path to an object centric approach with EF? Will I be swimming upstream going that route? Any good starting points?

• Converting DAO to ADO

  - by webworm

  I am working with an Access 2003 database that has a subroutine using DAO code. This code loops through the table definitions and refreshes the ODBC connection string. I would like to convert this to ADO so I do not have to reference the DAO object library. Here is the code ... Public Sub RefreshODBCLinks(newConnectionString As String) Dim db As DAO.Database Dim tb As DAO.TableDef Set db = CurrentDb For Each tb In db.TableDefs If Left(tb.Connect, 4) = "ODBC" Then tb.Connect = newConnectionString tb.RefreshLink Debug.Print "Refreshed ODBC table " & tb.Name End If Next tb Set db = Nothing MsgBox "New connection string is " & newConnectionString, vbOKOnly, "ODBC Links refreshed" End Sub The part I am unsure of is how to loop through the tables and get/set their connection strings.
