Hi,
I have met some problems when I opened the same database file twice in
the same process.
Why are you opening the same database twice?
Are you trying to simulate multiple processes or threads?

Version 1.10 released with C++ source
I am impleneting a basic DB class name RecordDB to store some data of
Record class for our project. Any
child class derived from Record will store data into the different
tables through correspongind child class of
RecordDB class. Although storing the different tables, all of the record
will be stored in the same database with
same db file.
For example, class Record_A uses class RecordDB_A to store records in
the table "records_a" of database "records",
while the class Record_B uses RecordDB_B to store records in the table
"records_b" of database "records". At the
loading period of the program, the RecordDB_A will open database and
create table, RecordDB_B will open
database and create table and the warning of "SQL error or missing
database" will be occurred when they insert
data into seperate tables. But if I close the database after the
creation of tables any warning will NOT happen.
Currently, there is only one process(thread) in my program, any
manilpute of database will be called exclusively.
Thanks,
