In a similar vein to my previous posts about carriage returns in
values in a database, I now have an issue with quotes (ie: ")
It seems that the csv output from SQLite has a major problem/error.
Within CSV format, a quote should be returned as a double quote,
within quotes. For
I can't find an example, but it seems like there ought to be
syntax to use bind to inline selection variables, instead of
having to have a callback function.
sqlite_prepare(db,"select ?foo,?bar from table");
How long a post to sqlite-users is ok. I have performance question about
updates but the message
that explains it, although clear, runs to almost 400 lines. There is a
company ftp site I can use as an
alternative to point to some software and test results. The issue is
performance with updates.
Sorry.. Pressed send before completing the explanation. Most of the
time is spent actually just creating the db representation of the
library, which is a fairly significant amount of time - it's inserting
at about 3-5 mp3 files per second into the DB, but that's only a
profiled release build.
This actually isn't really something that really has a user interface
(at least not at the moment).

Re: "..a possible optimization I'm thinking of ..."
Is it simple to place, say, 10 SQL Bind operations in series, then see if
this time is even perceptible?
Since this is a human interface, is it not likely that any efforts to avoid
the binds will go unnoticed because the execution time is so

Thanks for ur reply. I searched in the whole source code i could not find SQLITE_NO_SYNC flag.
Also i tried the following in my c code, after sqlite_open() was success.
sqlite_exec(pDbHandle,"PRAGMA synchronous=FULL;", NULL, NULL, );
Even this did not seem to work. How do
*"Compilation Options For SQLite" page is too old: last modified on

"SQLITE_OMIT_VIRTUALTABLE" is not listed.
Your best bet here is to post a bug report asking for the new options to
be added to the documentation.
Thanks for the helpful reply - it does seem like it'll probably be be
better and easier to compile a new statement every time - a possible
optimization I'm thinking of making is that I'll cache the fields
selected in the previous query - that way I'll only need to recompile
the query every

Currently i am going through the process of getting a compilation of
sqlite 3.3.7 going via cross compilation to mingw hosted on a linux x86

Thanks, that works.
The syntax i used is allowed in MS SQL.
