Okay, next question: Does the query you're testing this with obey the
requirements needed to use the partial index (see
https://sqlite.org/partialindex.html#queries_using_partial_indexes)?

Memory access is much faster than disk access. If you're using actual spinning
hard disks,
I noticed that my DB import process is much slower when run on the DB on
disk, vs. in memory. It reads files and runs a massive amount of
inserts/updates.
Why is this? Is there any way to speed it with disk without using
in-memory DB?

Yes a non partial index beyond column 64 works as I would expect.

Why not just add the amalgmation to your source then do C
function calss. I do not get why you would use a dll when you
can just link in the amalgamtion into your program and have full
access to the latest version.

System.Data.SQLite is generally considered
Jordy Deweer asks about alternatives to System.Data.SQLite because: “I run into

I’ve used that module for several projects and found it to be generally robust.

You’re not handling errors correctly, then. I think you said you’re using
Python? Then the query will probably throw a Python exception; you need to
catch that and handle it appropriately.

That should be CAST(round(x,0) as integer) if you want the rounded result as an
You have to look at the original dates. The date you're giving it for the first

What OS are you using ?
What programming language are you using ?
Are you calling the SQLite C library directly or using a shim ?
Does your program close each database

Hi,
I'm seeing hot journal frequently in our SQLite installation. We use VFS
which does some checksum and other operations. There are no abnormal
scenarios such as power off, process crash, abandoned transactions... DB is
opened by 10-20 processes each of which can have multiple threads.

Hello,
When working with Apple iOS databases, I found something strange when
dealing with dates. Apple iOS databases store dates as seconds from
2001-01-01 (31 years after unix epoch). But from 2015-03-02 to 2016-02-29
there is a offset of one day if '31 years' modifier is used.
To reproduce,
Don't put raw user input where code is expected. Match strongs are code.
You need to encapsulate (eg escape) or filter (delete bad characters) match
strings outside sqlite.

Hi,
I seem to have run into a limit where SQLITE doesn't use an index correctly if
an indexed column is over the 64th column in the table. It's a partial index
like:
CREATE INDEX idx ON
table(A, B DESC, C, D)
WHERE A > 0
Where A and B are columns 70 and 72 on 'table'.

Hi,
In the documentation alphabetical listing, it threw me off when I was
lookup up the JSON1 docs and didn't find them under "J", due to the title
being "The JSON1 Extension".
Just a suggestion: you might strip leading "The " from the titles in the
documentation list?

Hi,
Thanks for look into it. I checked its readme

It does not mention tokenizer at all so I guess you are right, it probably does
not support that at all.

The ICU extension (as in icu.c) does not contain the tokenizer ... it only

Looking in the amalgamation it appears that the icu tokenizer module is defined

Why is that ? Is the whole point to build icu
