Single quotes are used for text literals. If you want to quote
identifiers (e.g. because they are keywords) use backticks `identifier`
or double quotes identifier or

Hi everone !
I have a question about C binding for sqlite. I have seen those for
integer, float... but I was wondering how to deal with a NUMERIC (x, y)
type ?
We can't use float or double, we could loose precision, so maybe with a
string ?
If someone has a solution, I will really help me.
Thanks
I'm assuming you care about rounding and precision because you are doing some
sort of financial application. In that case, you'd want to be doing decimal
floating point math. This library will probably do the job for you, but there
should be arbitrary precision libraries out there if not. . .

Second way will work too. It correctly declares x INTEGER and SQLite
understands this. See
Hi Simon,
thanks for the response below.
as for your questions:
1. I am using version 3.3.6 of sqlite.
2. My journal mode is memory
3. I am opening a transaction and then do 5 inserts before
committing and opening a new transaction
given the above, what are the requirnments (disk-wise)
I have observed a peculiar behavior for timeouts in transactions when
a transaction begins with a 'select' statement. Basically, it seems
like the timeout setting is not honored in this instance and if an
'update' statement follows the 'select' statement, a 'database locked'
error message is
Thanks Sean and Simon :)
@Seam : The library seems interesting, but I would not use an external
library, as I use C as interface for Ada.
@Simon : Do you mean to store as integer or string whereas the Numeric
(x,y) column type exists, in order to have a nice binding in C ?
It's sure that I want

The numeric (x,y) column type does not exist. SQLite supports only the
following five types:
Well, when I quiclky read the paragraph about types I understood that they
were existing... In fact not, so I completly agree with your solution, It
seems
to be the best one to allow comparison or sum. I will save the 'cents' in
integer and do multiplication and division and you said.

You can do conditionals via WHERE clauses, as others have pointed out.
You can also use WHEN clauses on triggers.
Think of it as statement IF condition. And remember that the
WHERE clause can refer to all sorts of things, including parameters
from the application (something like WHERE @foo =
Hi,
I would like to know if I am dealing with a bug or a backward incompatible
change that I am not aware of.
Consider this example:
CREATE TABLE [table2] (
[id] INTEGER NOT NULL ON CONFLICT FAIL PRIMARY KEY ON CONFLICT FAIL
AUTOINCREMENT,
[isActive] INTEGER NOT NULL ON CONFLICT FAIL

I've always thought that because SQLite didn't enforce data types, I could
do what I have in the example, and this has worked! So, is this a bug in
more recent versions of SQLite or an intended change that I am unaware of?

That declaration only does type coercion on the value stored in the
