Allow ALTER TABLE ... IMPORT TABLESPACE without creating the table followed by discarding the tablespace. That is, assuming we want to import table t1 to t2, instead of CREATE TABLE t2 LIKE t1; ALTER TABLE t2 DISCARD TABLESPACE; FLUSH TABLES t1 FOR EXPORT; --copy_file $MYSQLD_DATADIR/test/t1.cfg $MYSQLD_DATADIR/test/t2.cfg --copy_file $MYSQLD_DATADIR/test/t1.ibd $MYSQLD_DATADIR/test/t2.ibd UNLOCK TABLES; ALTER TABLE t2 IMPORT TABLESPACE; We can simply do FLUSH TABLES t1 FOR EXPORT; --copy_file $MYSQLD_DATADIR/test/t1.cfg $MYSQLD_DATADIR/test/t2.cfg --copy_file $MYSQLD_DATADIR/test/t1.frm $MYSQLD_DATADIR/test/t2.frm --copy_file $MYSQLD_DATADIR/test/t1.ibd $MYSQLD_DATADIR/test/t2.ibd UNLOCK TABLES; ALTER TABLE t2 IMPORT TABLESPACE; We achieve this by creating a "stub" table in the second scenario while opening the table, where t2 does not exist but needs to import from t1. The "stub" table is similar to a table that is created but then instructed to discard its tablespace. We include tests with various row formats, encryption, with indexes and auto-increment.

# Embedded server uses absolute path, causing result mismatch in warning messages when .cfg is not copied over. Given we have tested importing without copying cfg in other tests, we don't do it here.
