But in retrospect I feel what you describe here offers users a choice of how to treat a single char. Either as a tiny integer (CHAR) or as a one-byte text [CHAR(1)]. It is probably best to keep this behaviour. regards, Markus -- Markus Hoenicka [EMAIL PROTECTED] (Spam-protected email: replace the quadrupeds with "mhoenicka") http://www.mhoenicka.de - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ ___ libdbi-users mailing list libdbi-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libdbi-users

Ok I can't do a atoi() because is out of my control. But in change the struct of table to include a CHAR(1) than CHAR. And I can get CHAR(1) like string. thanks On Thu, Oct 23, 2008 at 11:10 AM, Claudiu CISMARU <[EMAIL PROTECTED]> wrote: > >> But http://sqlite.org/datatypes.html and >> http://sqlite.org/datatype3.html says: >> >> "The search for these strings in the type declaration is case >> insensitive, of course.

I don't really think. This text explain how the data it's represented internally, inside the sqlite database file, not how it's presented to the user. In fact, the driver helps you, transforming that data to a numerical value, as you use it in your software. If it remains text, then you have to call atoi() on that field to get the numerical value. -- Claudiu Nicolaie CISMARU GNU GPG Key: http://claudiu.targujiu.net/key.gpg T: 0755135455 E: [EMAIL PROTECTED], [EMAIL PROTECTED] signature.asc Description: This is a digitally signed message part. - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/___ libdbi-users mailing list libdbi-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libdbi-users
