View as plain text  
this is strange, when i do this..
===============================================
mysql> start transaction;
Query OK, 0 rows affected (0.00 sec)

mysql> insert into tbltemp (tmp_crdd_no,tmp_serial_no,tmp_date)
values('100','100',NOW());
Query OK, 1 row affected (0.00 sec)

mysql> select * from tbltemp;
+--------+--------------+---------------+----------------------+
| tmp_id  | tmp_crdd_no  | tmp_serial_no | tmp_date                    |
+--------+--------------+---------------+----------------------+
|      1      |         100        | 100                | 2005-06-08
03:16:58 |
+--------+--------------+---------------+----------------------+
1 row in set (0.00 sec)

mysql> rollback;
Query OK, 0 rows affected (0.01 sec)

mysql> select * from tbltemp;
Empty set (0.01 sec)
=============================================

=============================================

mysql> start transaction;
Query OK, 0 rows affected (0.00 sec)

mysql> LOAD DATA INFILE '/usr/local/apache2/htdocs/test.csv' INTO TABLE
tbltemp FIELDS TERMINATED BY ',' LINES TERMINATED BY '\n'
(tmp_crdd_no,tmp_serial_no,tmp_date);
Query OK, 47 rows affected (0.01 sec)
Records: 47  Deleted: 0  Skipped: 0  Warnings: 0

mysql> select * from tbltemp limit 10;
