• Is there a way to store and access a SQL CE (.sdf) database in isolated storage?

  - by phredtalkpointcom

  I have a .Net application which must store all it's local data in isolated storage. I want to start using SQL CE to store this data. I can't find any documentation on how (or even if) this is possible. Is it possible to use isolated storage to store a SQL CE database? If so, what would the connection string look like (or is there some other way you would need to open the database)?

• Is it dangerous to keep an admin page to administer your database?

  - by Scarface

  Hey guys I have an admin page that checks if you are admin before submitting any queries, and contains a header to the index page if you are not admin, but I am worried about protecting the page. I am concerned someone may be able to destroy my database with it. Does anyone have any recommendation into protecting a page like this, if not, should I just manually admin my database through phpmyadmin and delete the page all together?

• how do you translate a space value in a database field to a null in .NET with Fluent NHibernate?

  - by gabe

  I am working with a legacy database that stores "blank" values as a single space. Is there a way with Fluent NHibernate, either by way of a convention or mapping override, that I can translate this "blank" value as a .NET null? (I know that I will need to save nulls to this database as a single space still but I will use an save event listener for that).

• Is there a PHP-based source code management system?

  I'm looking for a PHP-based tool for managing source code. Basically like a wiki but for code. I know that SVN or CVS may be the better option, but I just need something basic that allows users to collaborate. I don't need the ability to checkout or anything like that.

• How to generate custom JSESSIONID, based on some hash of user's data in order to replicate session

  - by Shaman

  Is it possible to override Tomcat's embedded generator of JSESSIONID, to be able to create custom values of this cookie, based on user's login? Why do I need this: I have a load balancer with "sticky sessions", configured to route requests with the same JSESSIONID to the same server, and I want to prevent situation, when same user can start two different sessions on different servers.

• Gridview - Is it necessary to grab data from database every time a filter, sort, or paging event occ

  - by hamlin11

  Regarding gridviews that are not bound to a Data Source Control: In most GridView tutorials that I have seen, when just about any GridView event occurs, the end of the event handler will include BindDataGrid(). In some form, these BindDataGrid() functions 1) Grab data from the database 2) Assign any Filter or Sort expressions to the data, and 3) Bind the gridview to that data source (usually a DataView or DataTable. Is there a better way to provide filterable & sortable data to a GridView without having to hit the database so often? Thanks

• How do you stop a user-instance of Sql Server? (Sql Express user instance database files locked, eve

  - by Bittercoder

  When using SQL Server Express 2005's User Instance feature with a connection string like this: <add name="Default" connectionString="Data Source=.\SQLExpress; AttachDbFilename=C:\My App\Data\MyApp.mdf; Initial Catalog=MyApp; User Instance=True; MultipleActiveResultSets=true; Trusted_Connection=Yes;" /> We find that we can't copy the database files MyApp.mdf and MyApp_Log.ldf (because they're locked) even after stopping the SqlExpress service, and have to resort to setting the SqlExpress service from automatic to manual startup mode, and then restarting the machine, before we can then copy the files. It was my understanding that stopping the SqlExpress service should stop all the user instances as well, which should release the locks on those files. But this does not seem to be the case - could anyone shed some light on how to stop a user instance, such that it's database files are no longer locked? Update OK, I stopped being lazy and fired up Process Explorer. Lock was held by sqlserver.exe - but there are two instances of sql server: sqlserver.exe PID: 4680 User Name: DefaultAppPool sqlserver.exe PID: 4644 User Name: NETWORK SERVICE The file is open by the sqlserver.exe instance with the PID: 4680 Stopping the "SQL Server (SQLEXPRESS)" service, killed off the process with PID: 4644, but left PID: 4680 alone. Seeing as the owner of the remaining process was DefaultAppPool, next thing I tried was stopping IIS (this database is being used from an ASP.Net application). Unfortunately this didn't kill the process off either. Manually killing off the remaining sql server process does remove the open file handle on the database files, allowing them to be copied/moved. Unfortunately I wish to copy/restore those files in some pre/post install tasks of a WiX installer - as such I was hoping there might be a way to achieve this by stopping a windows service, rather then having to shell out to kill all instances of sqlserver.exe as that poses some problems: Killing all the sqlserver.exe instances may have undesirable consequencies for users with other Sql Server instances on their machines. I can't restart those instances easily. Introduces additional complexities into the installer. Does anyone have any further thoughts on how to shutdown instances of sql server associated with a specific user instance?

• How to get distinct results in hibernate with joins and row-based limiting?

  - by Daniel Alexiuc

  I'm trying to implement paging using row-based limiting (for example: setFirstResult(5) and setMaxResults(10)) on a Hibernate Criteria query that has joins to other tables. Understandably, data is getting cut off randomly; and the reason for that is explained here. As a solution, the page suggests using a "second sql select" instead of a join. How can I convert my existing criteria query (which has joins using createAlias()) to use a nested select instead?

• Can i openly speculate based on App rejection that the iPad has xxx MB of memory?

  - by GamingHorror

  If i were to calculate the iPad's amount of RAM based on just the one fact that my iPad App got rejected due to memory warnings twice, and me fixing it, would this violate the developer NDA? Obviously i know how much memory my App uses, how much the iPhone OS is likely to use and estimate the amount reserved for video memory, then i can deduct from that that the iPad has xxx MB of memory. I just wonder if i can say that number publicly without violating any NDA?

  I'm looking to use named_scope to find records based on a method in the model.

Any ideas?

  I'm trying to implement a database build using VSTS 2008 Database Edition. The build always fails on the following constraint: ALTER TABLE [dbo].[tablename] ADD CONSTRAINT [DF_tablename_date] DEFAULT (CONVERT([varchar],dateadd(hour,(-1),getdate()),(1))) FOR [date]; The error that it shows is the following: TSD03082: The name "hour" is not permitted in this context. Valid expressions are constants, constant expressions, and (in some contexts) variables. Column names are not permitted. Anybody have an idea what is wrong here?
