sqlite via c++, opening multiple sqlite files

问题

How do I connect multiple sqlite files into a single sqlite3* handle, in C/C++? I'm thinking it's possible considering there's a command called ATTACH, but do not know how to do so in C++. Thanks in advance.

Answer (thanks to Robert)

sqlite3_exec(db, "ATTACH 'C:/tmp/tmp.sqlite' as mytmp");

回答1:

Execute the ATTACH DATABASE SQL command:

ATTACH path_to_database AS database-name

You can then refer to tables in the attached database as:

database-name.table-name
