It is pretty, runs well and is easy to use. Better than "decent".

Re: [sqlite] commit and rollback
Why not just test the status returned by sqlite3_step? Use
sqlite3_prepare_v2 to make the returned status give more information.
When you get an error just finalize your COMMIT statement and move your
pointer from the prepared COMMIT statement to a ROLLBACK and shortcut
the transaction. Instead of committing you will rollback.

i think its really a good solution to this problem. However, im required to
implement the c apis of sqlite..so i need to use the sqlite3_commit_hook and
sqlite3_rollback_hook..im doing some prototyping to see their
functionalities but i really cant make it work..and i also cant find some C
sample source code using these apis..if it is possible, can someone post
some c code using these apis?..
thank you and more power!

SQL *is* part of the API of SQLite. There is no separate C API to implement transactions; they are part of SQL. The commit and rollback hooks are called when someone uses the relevant SQL statements. They cannot be used to do what you have described, a transactional batch insert. - To unsubscribe, send email to [EMAIL PROTECTED] -

[sqlite] Re: Nonexistant Delimiters?
Argh, I feel like an idiot. I had my SQL syntax wrong because I messed up some delimiters. Now that I have that straightened out, it works fine. I think this will make separating strings a lot easier for me. Andrew On Nov 26, 2007 7:32 PM, Andrew Wiley <[EMAIL PROTECTED]> wrote: > I'm havinga large bit of encoding confusion.

It was because of wrong initialization of a global variable and crashed because of side effects. regards Andreas - To unsubscribe, send email to [EMAIL PROTECTED] -
[sqlite] Running SQLite tests
Hi- Is there any documentation on how one would run the SQLite tests? I'm thinking it would be an excellent test for my particular platform port. I'm seeing the test directory in CVS, but not exactly sure what to do with the test files. Thanks, Mark - To unsubscribe, send email to [EMAIL PROTECTED] -

Andreas, While there might be a strange memory bug going on, the bigger issue is that if you have a db member of the Cache class, you're declaring a local db variable that's masking the member. That could be leading to unexpected results later on if you're expecting to use it.

Re: [sqlite] Threading (again)
SQLite is completely threadsafe. So we can share a single database connection across threads, it the underlying OS is Okay. But I guess we can not share a sqlite3_stmt prepared statement across threads threads. Am I correct. Or am I missing something? -- Sabyasachi
