Apparently, in trying to make numbers out of strings, it is interpreted as
7 - 5 = 2 and the part after the comma is truncated.

But, would someone explain the result of 2? Sorry for this child-like
Well, OK, but you attributed the quote to the wrong person. :)

From the SQLite3 shell (recent version), use the readfile('filename')
function to import into a blob field, and the writefile('filename',field)
for exporting back to a file.

I second the idea of a kind of "WARNING: All your work will be lost, are you
sure you want to quit? (y/N)" on trying to exit, but *ONLY* if the
application was started by (double-)clicking on it, otherwise the warning
will be a nuisance when running test scripts.

Hello,
When .importing from a csv file (for example) with a command like ".import
data.csv data" if the table does not exist, the table is created using the
first row of data.csv as the field names.
But if the same file is imported a second time, the first line is treated as
data.

Hi all,
First of all, this is not about using SQLite as an embedded library from C,
or whatever other language. It does not affect the sqlite3.c file at all.
It only applies to the shell (so logically, it only affects shell.c)
So here’s my suggestion for what (I feel) is a significant
Stored procedure would be a great addition. But they would be not in the
shell, they belong in the library core.
Scripts are already a part of the current functionality. Only they have to be
external. There no IFs, loops, or whatever other constructs. Those who say

The only thing I noticed which maybe of interest in relation to speed

On the other hand, creation of a view could ignore the dependencies, and only
check them at run time.
It's curious that the following sequence seems to behave this way:
create view a as select 1;
create view b as select * from a;
select * from b;
.d
drop view a;
.d
select * from b;--Error:
Exactly!

Trying to import data into a table the operation stops on first error (actually
a rollback seems to be performed) because of column number mismatch.
Why does it not follow the .BAIL ON/OFF setting? And, why rows before the

So, in .BAIL OFF mode, I expected errors to
When trying to load a data file with ,"", sequences (for empty field), there
are quote escape related errors.
Manually converting ,"", to ,, allows the file to be loaded. According to
RFC4180, the double quote is an escaped quote if found inside a string. The
leading quote should not be
For example, here's a sample (header + one line of data) that fails -- a lot
more lines fail but I cut it down just to show the problem:

I did. I just download the precompiled binaries for Windows, and this is
what I see (for that sample data file):

Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite> .sep ,
sqlite> .import data tab
OK, now copy the data line several times, and you'll see there are errors
for several lines, unrelated to the final CRLF (which I removed this next
sample).
-- data --
"Year","Debt","GDP1","GDP2","RGDP","dRGDP","Infl","debtgdp"
"1833","","49.3275923134","","118.3483703666","","",""
It turns out that CRLF may have something to do with it.
I can get rid of the errors, either:
1. if I replace "" with nothing,
OR
2. if I save the file as Linux style (LF only).
