Hello,
what do you mean, please ? What code is not shown:my own code (and what

Indeed. Any operation in ORDER BY (even things like "ORDER BY id||''")
result in scan + temp b-tree.
Thanks again.

There is an error in your code. Which you have not shown.

Hello,
the examples for the back API as exposed here:

work not for memory database. Tested with latest amalgamation VC++ VS 2013.

I suspect there's indeed some special behavior not obvious at the moment.
I'll try to gather some additional information if it's possible or detect
this specific behavior

I test the two sql statement. It almost the same speed.

Hi,
I have a compatibility problem with my vfs implementation of memory
databases. I once implemented it successfully probably with a version
3.6.something. Today I tried to create a new database using the same code
with the latest (3.11.1) version (the procedure is when no prior db data
exists,
hi,all
As usual, we judge a record is exist or not in a data base is :select id
from table_name.
Except the above method, Is there any method which could judge a record is
exist or not much faster than the above method.
I am looking forward to hearing from you.

This involves two things which are not built into SQLite:
CONVERT()
SCOPE_IDENTITY()

Another possibility to test for speed is
select 1

It doesn't work with FTS5.
Both FTS3/4 and FTS5 allow for user-defined tokenizers, but the
interface is not the same. So the ICU tokenizer
Hi,
Cross-compiling SQLite from source on Linux using sqlite-autoconf-3110100, the
--disable-static-shell option no longer works, a static-linked-sqlite3 binary

The regression appears to have occurred here:

Assuming the "id" is the primary key of your table "table_name", your statement
will list the id of all the records present (full scan, reading every entry of
the implicit primary key index).
To find out if a specific record exists, use "select count() from table_name
where id = " to return a
When I go to page
http://www.sqlite.org/download.html
then there are a 32bit and a 64bit DLL library version of SQLite.
Unfortunately there is only the 32bit version of the stand-alone engine.
Ok, I know, I can run the 32bit version as well under 64bit Windows but I
prefer a 64bit version
