Re: Re: [sqlite] Detached database still owned by process

[Anders Holmberg]

Thanks for the responses.

The ProcessExplorer was just the thing I needed! With it I can see
that sqlite _does_ release the file handle and that my program must
hold on to it in another way sometimes. Now I have to find that
sometime;)

Thanks again...

Sysinternals' Process Explorer can be used to verify that your process
does indeed still have a handle to the file, or search for another
process that does, if you need it.

In the .NET application case, make sure (when using managed I/O) that
an explicit .Close() or .Dispose() is being done; don't rely on GC.
This doesn't apply to an sqlite wrapper in the detach case, though.

I've had this same issue with files written by .net applications.
I haven't found what's causing mine yet... It might help to wait
10 seconds or so and retry the operation

My problem is that sqlite keeps hanging on to the first database even after
I have made a detach; which makes it impossible for me (or my program) to
delete the original file.

Unable to reproduce.  "lsof" shows that sqlite3 closes the
file handle just fine when you detach on linux. Perhaps your detach
is failing.  What does "PRAGMA database_list" show after the
detach?

[sqlite] Detached database still owned by process

[Anders Holmberg]

Hi

I am using sqlite (version 3.3.7) on Windows and I am loading one database
(stored in a file) into another database (:memory:) using the attach /
detatch scheme described on the sqlite site.

My problem is that sqlite keeps hanging on to the first database even after
I have made a detach; which makes it impossible for me (or my program) to
delete the original file.

Is there something more I need to do make sqlite "forget" about the file?
