Hello everybody,
I already saw this discussed in 2006 (see
http://www.mail-archive.com/sqlite-users@sqlite.org/msg14703.html), but there
was no
final answer.
I'm thinking about storing some bigger data blocks in a database, or, if that's
not
efficiently doable, address files in the filesystem
why is the data file locked after writing?
the last printf() result is:
# IN END, ret = 5
according to the Result Codes:
#define SQLITE_BUSY 5 /* The database file is locked */
It means to the database file is locked? why does it happen after writing?

Because you still have a statement in progress. Finalize it with
sqlite3_finalize.

I looked into it but couldn't find the exact reason for my bug.
If you have any idea please let me know.
Also I would appreciate, if you can let me know what does this error mean

*** in database main ***
What is the correct way to specify that SQLite should perform no caching
(or at least minimal caching)? PRAGMA cache_size=0 seems to have no
effect - either it continues to use the default, or tries to caches
everything.
Cheers,
Dave.

The best place to get answers to .NET-related issues with the
System.Data.SQLite provider is:

I've got plenty of forums over there so we don't clutter up the list with
wrapper issues unrelated to the engine itself.

Dennis,
question on an old post of yours below...
on that update statement, is the SQL optimizer smart enough to not
rerun that select statement for each column in the update's set

Both PRAGMA cache_size=10 and PRAGMA cache_size=1 result in minimal
caching, which is great. What is the expected behaviour of PRAGMA
cache_size=0 for the default page cache? I'd like to know whether
setting cache_size=0 has some special significance, maybe it's a case I
need to prevent.
