Re: [sqlite] SQLite Encryption Extension (SEE) and Public Domain Sqlite

If you hash the username too you don't have that problem. Passwords should always be a 1-way hash. It's actually best to collapse username/password into a single one-way hash. That way it's very difficult to crack it. You can use a user "account#" value that users would have to track for

[sqlite] DROP TABLE yields SQLITE_LOCKED from user-defined function

I have a user-defined function that I register with create_function. Inside my function I try to drop an r-tree virtual table, but I get the error SQLITE_LOCKED. Is there something special one needs to do in order to drop a table from inside a user-defined function? To test, I call it simply

Hey. Currently createCollation() function in main.c is structured like this: 1. functions starts and immediately computes int nName = sqlite3Strlen30(zName); 2. then there's a ton oh checks some of those checks lead to early return 3. then there's if( (pColl->enc & ~SQLITE_UTF16_ALIGNED)==enc2 )

Thanks for the hint. Using a separate data context for the other thread solves the problem. But it doesn't make the situation much better, because the data context seem to have separate cashes. So it does not help to cash stuff in the background, because it won't be ready for the main thread

I probably am using a single SQLiteDataReader, although I never explicitly handle one. context = new DataContext(_connection); context.GetTable(); I do all queries on such a table object via Linq. Is there a way to control the DataReader involved with such a query? On Thu, Jul 7, 2011 at
