• SQL Compact - Hang on invalid file

  - by eWolf

  I use Linq to Sql Compact with code generated by sqlmetal. When I open an invalid database, like eg an mp3, I can create the DataContext without getting an Exception. But when I query any data or call DatabaseExists, the application hangs. Why is no exception thrown? Is this a known problem?

• Negative Primary Keys

  - by bjax

  Are there any repercussions using Negative Primary Keys for tables (Identity Increment -1, Identity Seed -1 in SQL Server 2005)? The reason for this is we're creating a new database to replace an existing one. There are similar tables between the two databases and we'd like the "source" of the information to be transparent to our applications. The approach is to create views that unions tables from both databases. Negative PKs ensures the identities don't overlap.

• Change MS Access to Exclusive on the fly

  - by Nate

  I have a process in an MS Acess database that the users will usually run once daily, but could be more or less. It takes several minutes and requires temporary exclusive access because it deletes and recreates the main table. I have code to check to see if there are other users in the db before the process starts, but is there a way to change the access to "exclusive" at the beginning, and then change it back to open access at the end? Thanks for any help.

• In php, Prepare string and create XML/RSS Feed

  - by Bill

  I want to create my own RSS/XML feed. I fetch data from the database to display, but keep getting invalid character errors. If the string has an ampersand or other strange characters in it, the XML will be invalid. I tried using urlencode and htmlentities, but these don't capture all possible characters which need to be escaped. Does anyone know of a PHP function which will prepare a string for XML output?

• Where does the creation of permissions live in Django?

  - by lazerscience

  I need to do some debugging, because the permissions for one of my models are created wrongly. So I tried to find the piece of code where Django creates the permissions upon syncdb and writes them in the database, but I haven't been successful at all; maybe I just overlooked the right lines of code, but if somebody can point me out the right module / line of code where this happens I'd be very happy!

• When it comes to updating all rows in a table, does the method of locking matter for performance?

  - by Evan Carroll

  Question is a follow up to this. The SQL in question was UPDATE stats SET visits = (visits+1) And the question is, for the purpose of performance, does it matter if you lock all rows in stats in comparison to locking the table stats? Or, if the database uses a page-lock rather than a table/row lock?
