No Such Database and Windows Access Permissions
For my current (as of this post) position as a C#/.NET developer intern, I frequently replicate development databases to my local system through the Data Comparison tool in Visual Studio. One day, however, I got an interesting error when attempting to migrate data:
1 Internal error: Ese could not be initialized; No such database;
What do you mean, no such database? I can see the database right there! (Points at database on screen)
I scrounged the Google, as you do, with that error and came up with increasingly voodoo-like solutions from people that were in entirely different solutions. Eventually, I did find one other post that had the same issue, with the solution as the single comment.
If you came here from a Google search, panicked and looking for a fix:
TMP environment variables to point to another folder, such as
%USERPROFILE%\AppData\Local\Temp or any folder you drop somewhere on your system that has full access permissions.
The clever among you might say, “Wait, but that points to the same place I had it set to already!” And you’d be right. Most people have
TEMP/TMP set to
%USERPROFILE%\Local Settings\Temp, which contains the exact same data, but is a protected path in Windows. This is done through a symlink, resulting in both paths pointing to identical data on disk but with different permissions. The first provides full access to the ESE (Extensible Storage Engine) that handles SQL Server database files.
It’s quite the error, since one path to the same folder results in an error and the other doesn’t. Hopefully this helped; I wanted to get this solution out in more places since I’ve only found this specific solution in one other place.
