Question, does the %q operator offer any advantages over calling QuotedStr ?
Yes: The %q operator just duplicates internal quotes, it does insert quotes at
the beginning and the end of the string like QuotedStr does. You can can still
use sqlite3_mprintf's %Q operator for that.

Why Sqlite doesn't support just the use of offset in select statements?
As such SQL does support the use of offset only, without limit. But in
case of Sqlite it's not possible to use offset without limit.
Also what is mentioned on website is different from what is there in
parser.c file. On
I am using sqlite version 3.3.7
Also what I have noticed is limit ALL is not supported.
limit_opt ::=,
limit_opt ::= LIMIT expr,
limit_opt ::= LIMIT expr OFFSET expr,
limit_opt ::= LIMIT expr COMMA expr,
expr doesn't contain ALL.
Hello,
I'm trying to write an application which will merge two or more databases
together.
The rules are that duplicate records will be added together.
As an example we can have two tables:
user(id integer primary, name text)
and
orders (id integer primary, apples integer, user_id foreign)

A negative value is interpreted as ALL. This is also documented at

Unfortunately, Unicode specifies no such thing. There is no such thing
as _the_ Unicode collation, if only because collation rules depend on
locale.
Yes, what I mean is to define how individual locales are identified in
SQLite, like that already suggested 'en_AU', 'tr_TR', etc.

After thinking a bit, it occurs to me that there's a compromise for
the Unicode case that might be workable. The algorithm for collation
is pretty stable, it's just the locale data that's the problem. If
SQLite understands the algorithm, then locale data can go into special
