The filename of the database follows the same semantics as the filename argument to sqlite3_open() and sqlite3_open_v2(); the special name ":memory:" results in an in-memory database and an empty string results in a new temporary database.

The filename argument can be a URI filename if URI filename processing is enable on the database connection.

The schema-names 'main' and 'temp' refer to the main database and the database used for temporary tables.

R-38412-06710-13373-27041-27382-60302-02109-00077 tcl slt th3 src

If the name of the table is unique across all attached databases and the main and temp databases, then the schema-name prefix is not required.

/* IMP: R-38412-06710 */

R-55636-16561-36868-23956-09727-21947-00276-50271 tcl slt th3 src

If two or more tables in different databases have the same name and the schema-name prefix is not used on a table reference, then the table chosen is the one in the database that was least recently attached.

/* IMP: R-55636-16561 */

Transactions involving multiple attached databases are atomic, assuming that the main database is not ":memory:" and the journal_mode is not WAL.

R-34979-54336-33279-53576-25867-30233-28350-04331 tcl slt th3 src

If the main database is ":memory:" or if the journal_mode is WAL, then transactions continue to be atomic within each individual database file. But if the host computer crashes in the middle of a COMMIT where two or more database files are updated, some of those files might get the changes where others might not.
