This is copying the whole table twice. Is there any reason why it
shouldn't be:
BEGIN TRANSACTION;
CREATE TEMPORARY TABLE t1_backup(a,b);
INSERT INTO t1_backup SELECT a,b FROM t1;
DROP TABLE t1;
ALTER TABLE t1_backup RENAME TO t1;
COMMIT;
t1_backup is a temporary table. You want a permanent table in the main
database. ALTER TABLE cannot magically move a table from temp database
to main - the two databases are physically in two different files.
