[sqlite] Database layout in memory

Thank you for the quick response, Keith! As I understand it, the SQLite Backup API?s only work with an SQLite object. E.g.: sqlite3_backup_init() needs a pointer to the database to copy from. However, I do not have access to such a pointer, as the only thing I get is a raw binary dump of the

Thanks for reply? Simon. So you think that it better use autoindex instead of my own index for matching email and password from user input and database? How about sqlite queryplanner docs tell that said "To get the maximum performance out of a query with multiple AND-connectedterms in the WHERE

Of course, if the index on (email, password) was UNIQUE, then it would be *better* than a unique index on email only, for queries constrained on both email and password. Unless you tell it so, the computer has no idea the index uniquely identifies a single row, and you do this by CREATE

[sqlite] Fwd: Sqlite is secure with MD5?

Is TCL being used (you have to specifically include the TCL interface ONLY if you are generating a DLL to be loaded into TCL)? Did you enable the MD5 commands? Why? If you do not want them being added to your TCL interpreter, then I would suggest perhaps not enabling the option which
