Hi,
you transaction is implicit, so there has been an autocommit.
Look at this example !
mysql> start transaction;
^^^^^^^^^^^^^^^^^^
mysql> load data infile 'd:\\ldfile.txt' into table ldfile;
Query OK, 3 rows affected (0.00 sec)
Records: 3 Deleted: 0 Skipped: 0 Warnings: 0
mysql> select * from ldfile;
+------+
| i |
+------+
| 1 |
| 2 |
| 3 |
+------+
3 rows in set (0.00 sec)
mysql> rollback;
Query OK, 0 rows affected (0.03 sec)
mysql> select * from ldfile;
Empty set (0.00 sec)
This a not a good idea if the file is big. Ideally, truncate the table if there
has been a problem witha big file.
