Hi,
I have a situation where I always run into an SQLITE_BUSY error. It's quite
involved, here's the high picture:
-3 processes (A, B and C) each have a connection to the same db. Everybody
has a busy handler set for 5 seconds.
-1 of these processes (A) opens more than one connection,
You haven't explained what the second connection in A is doing. My
educated guess is, the two connections enter into a deadlock. This is
possible when at least one connection starts as a reader and later
attempts to write (the other could be a straight writer). The scenario
goes like this: the

Set your timeout to something very large (a million milliseconds ?) and see if
the problem just turns into unexpected delays instead of errors. You can

You may be mistaken. sqlite3_next_stmt() will return 0 if all
statements really are finalized
Now in my system I used sqlite to manage 2 database file A.db and B.db, and
each has a connection handle cA, cB.
My operation perform like this:
sqlite3_exec( select records from cA)
sqlite3_exec(begin transaction);
insert all records into cB;
sqlite3_exec(commit transaction);
All return
INTO main.mytable(col1,...colN) SELECT col1,...colN FROM dbA.myothertable
COMMIT
DETACH dbA
sqlite3_close B.db
