Richard, Sorry to bring this up again, but ive just finished testing the alternative strategies.
Having coded all 3 versions i still have a question about the sqlite3_step() problem which i think was isolated as the cause of my trouble a few days ago. Firstly can i clarify what you mean regarding the same moment. Do you mean that no two threads can be executing the call, or that no two threads can be in the middle of stepping through a series of results using the step function (assuming there is some context behind the scenes). Even if the threads involved are synchronised. I treat all of the api functions as synchronisation boundaries, so i would never allow two threads to call an api function at the same time. The reason i ask is because i assume it is ok to have multiple statements performing a sqlite3_step() at the same time in a single threaded environment. I know that internally sqlite turns everything into prepared statements and executes them using sqlite3_step(). And if this is the case, then in a multithreaded environment it should still be the same so long as things were synchronised ? Im confused because ive been told that it doesnt work, and i guess i just dont understand what is internally preventing it from doing so...
