Re: [sqlite] Recovery tool ?

Once I experienced a problem during testing where multi-threaded Win32 Application (using SQLite 3.3.4) was running (in development environment) and due to power-failure, rollback journal file was OK but disk bad-sector damaged the sqlite db-file. When I restarted App, db could not be opened

Re: [sqlite] Multiple SELECTs (and single SELECT) and TRANSACTION ?

It depends upon your application. For it to function optimally you should make each transaction on your application an SQL transaction, commit it on success or rollback if there is a problem. In that way you make each transaction atomic and maintain the integrity of your database. Since

Re: [sqlite] Foreign Keys

Parsing is a language term. You might recall being taught to parse a sentence into subject and predicate, then phrases, verbs nouns, articles etc. A computer language parser does the same thing, lexical analysis to extract the words and syntactical analysis to match to the grammar. That

Thanks Richard. I need btree indexing in a commercial project and looks like everybody is charging fee... and it wouldn't be a problem if I am the guy who is writing the check... I just did some simple stress test (inserting and query a million records) and you guys save my behind.

Hi Guys, I think I figure out my problem. Looks like I need to close the cursor and create a new cursor between the two Btree transactions. Then the second btree commit will go thru. Can someone explain to me why? Thanks. Regards, William -Original Message- From: William Chan

[sqlite] Foreign Keys

FOREIGN KEY constraints are parsed but are not enforced. Hi, what does the above statement on the SQLite website mean? Call me stupid but I do not understand the word "parsed", I was thinking it meant, it recognises them if you put them in your create table statement but it does not enforce
