SQLite Forum

Why data is lost in SQLite database with WAL mode on when connection is not closed properly?
As confessed in another thread, the OP is running two different versions of SQLite within the same "app" and is unable to discern if he is doing so within different threads or different processes.

I guess it is just interference from using two different SQLite libraries, possibly compounded by loss of POSIX locks if runnign within the same process.
