Ok, I was kinda hoping for a more "permanent" solution such as:
int sqlite3_cast_column_type(sqlite3* db, const char* zDBname, const char*
zTable, const char* zColumn, int newColumnType);
that would cast the column into

We tried as you mentioned. But we are restricted with the memory size and
the storage of the needed data occupies some MB's of space in the memory so
we cannot go for it. Is there any other work around to perform the scrolling

Kindly help in this

We have the amalgamated sqlite3.c source file under Perforce control
here and I don't recall any problems with diff, except I had to wait a
bit longer than usual.

Hi All,
I would appreciate help with the following scenario.
Suppose I have the following schema:
CREATE TABLE t1
(
f1 integer,
f2 text
);
CREATE TABLE t2
(
val integer
);
Suppose the following inserts statement are executed by two processes
over the above schema.

You cannot create a trigger which crosses between databases because
the system cannot know that the database will be attached when the
trigger fires. Triggers are part of the consistency guarantee, so
this is bad.
It would be interesting to have something like "CREATE TEMPORARY

Understood. I use the amalgamated source for maximum performance.

My experience is that this kind of problem tends towards a he-said,
she-said type of thing, and what happens in the end is that everyone
is correct from their perspective, but there was some little bit of
non-obvious thing that made one party's understanding of the encoding

Thanks, Mark!
I use the individual source files rather than the amalgamation,
for several reasons:
(1) Visual Studio has trouble generating line number info for
files that have more than 64K lines.
(2) Perforce (our version control software) has trouble diff'ing
two versions of a large file.
If you create a file on disk and set PRAGMA synchronous = OFF, you
should get pretty close to the performance of a shared in-memory
database on most modern desktop operating systems - maybe close enough
that you won't care to do anything beyond that. If you further look

That's what I do. Once your makefile is set up, make the "sqlite3.c"
target if you want an amalgamated source file. Be sure to carefully
coordinate the defined values between the preprocessing step (to
generate your source file(s)) and the build of your application/dll.
If you are using
I've got two processes running. Each has it's own instance of the database

Of course if I close and re-open I see the change but surely that's not
how this has to work.

Hi all,
I'm using the sqlite3_blob_* api to write a larger text stream incrementally.
Works a charm, but is there a way to
