Sorry about my ambiguous description.
Here is what I wanna do. Normally I use Python code to insert/update data of
two tables in my sqlite database file: *map and images*, table *map* stores
the indexs of pics, while table *images* stores the contents of these pics.
My Python code works well, untill the db file grows too big: I find some
pics I insert into the db file is incorrect, then I rerun my Python code to
update these pics with right ones, but the select result of table images is
still not right. So i use command-line tool to test it, and there goes my
problem, I find the update/delete operation not working or giving any error
message, while I can still insert data into the same file.

Of course I use the CLI after my Python script finishes all inserts,
otherwise the db file is locked and all my operations in CLI would retrun

I can't find this command in my CLI, and I use count_changes, here is the
schema and my commands. I think my delete operation returns correctly, but
after delete, the select result confuses me.
As you can see, insert works, and I can also delete/update this last
inserted record. It seems some pages of my db file is locked or something.
