Hi, I wonder if anyone else has asked a similar question. Basically, I have a huge tree I'm building up in RAM using Linq objects, and then I dump it all in one go using DataContext.SubmitChanges(). It works, but I can't find how to give the user a sort of visual indication of how far has the query progressed so far. If I could ultimat...
How do you refresh a database connection within a VB application to SQL Server 2005 so that whenever data is changed in SQL, such changes are picked up by the application? For now the application only picks up the changes after it has been restarted, and that is not what I want. ...

We are developing an application to do a "hearbeat" test of all our SQL servers (2000, 2005 and 2008), and we're trying to figure out the minimum permissions necessary on the SQL server to do that. (Platform involved is TBD, but should use a standard connection string). We are considering using a "SELECT @@VERSION" query, which should b...
In Sql Server, I have a table with an Identity primary key. Often I want the latest few new records, so I grab the Top n sorted by descending the primary key. Should I define the Primary Key index as Descending, or does it make no difference? i.e. if they are in Ascending order, then can sql just as efficiently work backwards? ...

Huge database in mssql2005 with big codebase depending on the structure of this database. I have about 10 similar tables they all contain either the file name or the full path to the file. The full path is always dependent on the item id so it doesn't make sense to store it in the database. Getting useful data out of these tables goes a...

I was given a database design which stores information about an organization and any changes that have happened or will happen to the organizations. Since pretty much anything can change about an organization, there is one table that only contains the unique OrganizationID's in a table called "Organizations". The changes to that organiza...
At work we have just started building an auditing framework for our database (i.e. to log what data has changed when it is created or updated). We'd quite like to implement this using triggers as data sometimes gets imported into the system from other places, not just via the front-end. This seems to be a fairly common solution. Howeve...
I'm running a SQL Server 2005 trace using profiler. I'm seeing some missing join predicate warnings, but I can't determine where its occurring with the data they are giving me. All I have is the transactionID. Any way to find out what object is causing this? ...

I upgraded from Sql Server 2005 to Sql Server 2008. I backed up the data in SQL Server 2005, and then I restored in SQL Server 2008. Next, I found the catalog under "Storage->Full Text Catalogs", and I right-clicked on it, and am trying to rebuild the Full-Text Catalog. The database is only 600mb. However, it keeps running for hours, and...
Our system runs on SQL Server 2000, and we are in the process of preparing for an upgrade to SQL Server 2008. We have a lot of trigger code where we need to detect a change in a given column and then operate on that column if it has changed. Obviously SQL Server provides the UPDATE() and COLUMNS_UPDATED() functions, but these functions...
