As you might have guessed from the timezone I am not at home atm, so I
do not have spare external disks.

what you say makes sense.
However it does not explain why the pragma checks are so slow.
Anyhow, npkasm, I will keep in mind for the future. Good point indeed.

Hi Mat,
We have been using SQLite in our Windows universal application both for
tablet and phone
We used SQlitePCL as the wrapper library to write our queries in plain sql .

I was wrong. Apologies.

Hi,
I have a database with NameTable having name records in it, I need to get the
row number of the first record in the sorted list of names for which the search
name matches.
Example, for below entries in NameTable
Name
1. PTN
2. ABCD
3. CDE
4. PQRS
5. AXN

Hi,
is there any target date when the preRelease branch gets over to a actual
release?
Is a really hard show stopper for our development at the moment. We checked
everything for compatibility before merge your current trunk to Visual Studio
2015 and we forget about the SQLite design tool. :(

Hi I am trying to run a SQLite database in a CE6.0 device (Psion Omnii
XT15). It runs the demo from
sqlite-netFx35-binary-PocketPC-ARM-2008-1.0.97.0.zip, which creates a db
from testce.exe, but on running my VB.net app it produces an error

I tried zpool scrub on both my disks and it returned nothing, I also
tried executing stress[1] on the disk and no error appeared in the log
or in stress itself.
However, coping the sqlite db on an external disk connected via usb3

Hi,
I was previously using System.Data.SQLite in a .NET library, and now want
to port this library to an Universal Windows library.
I cannot make the System.Data.SQLite work (since I guess it is not
portable), and found only LINQ style SQLite PCL libraries in NuGet ...
Is there a way that I can
Wouldn't be easier to simply add a parameter to sqlite3_initialize()?
E.g., a char const pointer to the tmp directory? That, if null,

Maybe I am oversensitive, but I found strange I have to use setenv to
setup a command line option about "where

The problem with foreign keys most of the time is not the the referenced

dependent table/field when they do not have a proper index, any time you

On Unix, unlink() after open is used.
On Windows, the FILE_FLAG_DELETE_ON_CLOSE flags is used when the
temporary file is opened.

Those times are completely typical for SQLite.
