Dude, Are you even reading what others have (very patiently) tried to explain you? Here's one more attempt. My advice (like everyone else in here) is to let SQLITE handle that for you with autoincrement. Asuming you don't take the advice, you can also try: int main() { ... .. . ... maxId =

Thank you, thank you, Igor! This relates to the earlier thread I had started titled "Speed regression after 3.6.17" where I was wrestling with a very slow query because the query optimiser was selecting an inappropriate index, one that was very chunky because the field was logical (0,1). This

As stated before, in general, you should not specify the ROWID on inserts, but instead, let the database engine choose it for you. This is true of most/all database engines. The syntax you're trying below is not supported. Indeed, even it were, max(ROWID) is the maximum ROWID *in use*. Trying

Re: [sqlite] Multi-process read_uncommited equivalent?

Be aware that the backup process will need to restart from zero after each write! Now, if you can setup some kind of IPC between your two processes, then you could have the update process update the disk base and send identical data to the reader process, so the latter can update a memory

Re: [sqlite] Multi-process read_uncommited equivalent?

First of all there's no multi-process equivalent of read_uncommitted. There's just no way to implement that. If you want such type of behavior with your current application structure then you should use some other RDBMS. For SQLite though I'd suggest you to use some variation of you 3rd approach:

[sqlite] Multi-process read_uncommited equivalent?

I have two independent processes that open the same sqlite database. One inserts data into a table and the other reads from the same table and creates reports. The reader process does something like "select * from table" and then does some heavy processing between each call to sqlite3_step(). It
