This may have been asked many times before but always seems to be a
valid question. On some machines with different compilers I get good
results using C99 strict compliance. On other machines, such as those
running Red Hat Enterprise Linux, I get terrible results.

I think this is a bug. However, looking at the code the way to achieve that is
to surround the string in double quotes which will cause exactly what appears
between the double-quotes to be stored. I think it is because of the way the
parsing and mprintf function works ...

It's odd that SQLite doesn't support this, since it's not uncommun to have
big Latin1 input files that can take a while to load in eg. Excel.
For others' benefit, GNUWin32's iconv is very fast:
"C:\Program Files\GnuWin32\bin\iconv.exe" -f "windows-1252" -t "UTF-8"

Unlike UTF-16, which uses 2 byte code units without a fixed endianess
(meaning to be robust you need to account for both little and big endian
encodings when reading files using it), UTF-8 uses a 1 byte code unit and
thus doesn't have any endian issues or a need for a byte order mark.

If you're on Windows, which cp1252 suggests, just make sure that you don't
end up with a BOM at the start of the file when you convert it. Windows
tools that output utf-8 are sometimes prone to add one even though it's
pointless to have.
On Linux etc., you can try
.import '| iconv -f cp1252 -t
How you would use bound parameters depends on what you are using to interface
with the sqlite3 database.
https://www.sqlite.org/c3ref/bind_blob.html for the C interfaces.
In something like python you would pass the bindings as a tuple to the execute
method of the cursor:

Maybe something like:
CREATE VIEW "Sum of Expenses Between two Dates" AS
SELECT Date,
sum( CASE
WHEN Date BETWEEN date('now', '-1 months') AND date('2019-11-04',
'-1 days') THEN Expense
ELSE 0
END) as 'Sum of Expenses:'
FROM Expenses;
On 11/15/2019 12:22 PM, David
So why do you need a case? What will not work with the simple:
select sum(Expense)
from Expenses
where Date between date('now', '-1 months') and date('2019-11-04', '-1 days');

Hello,
I have a big CSV file that's encoded in Latin1 (cp1252), while SQLite stores
strings as Unicode.
Neither Google nor ".help" helped to find if SQLite offers a switch to
convert Latin1 to UTF-8 on the fly before running the ".import" command.
Should I first convert the file into UTF-8
Hi,
I have a simple database, the 'Incomes_Expenses.db' on my system.
It's SQL is here:

Consider:
sqlite> .parameter init
sqlite> .parameter set :date '2019-11-15'
sqlite> .parameter list
:date 1993
How do I make it treat the value argument as a string and not as a numeric
expression that gets evaluated?

The SELECT returns zero lines. Therefore zero lines get inserted. You might
like to try one where the SELECT returns more than one line.

WRT Jose's original context, and just for my enlightment, what happens with the
following:
insert into t (a, b, c, d, e, idate)
SELECT a, b, c, 'y', e, '2019-02-12' FROM t WHERE a = 'p999';
where p999 does not define a record? Is a new record inserted with values of
a,b,c, and e null?

What I do is have any parent database setup done by having the parent spawn
a child process to do the actual database work, and return any data the
parent needs in the status or (if more than a

As can be seen below, the last query fail, despite the one before it
succeeding.
Yet the second argument is constant, thus it would seem "natural" for it to
work as well.
Could the error be "relaxed", when the non-first argument(s) to aggregate
functions are constant?

Thanks. Yes, this is great! Darn it, I didn't think of this. Thanks again.
