View as plain text  
Okay, I have a confession to make: I have never gotten Load Data Infile or 
mysqlimport to work.

Here's my CSV file, named "t_dmu_history.txt":

13071,299519
13071,299520
13071,299521
13071,299522
13071,299524
13071,299526
13071,299527
...

Here's my mysqlimport command:

mysqlimport -uaccess -pxxx --delete --columns=`dm_history_dm_id`,`DM_History_Customer_ID` 
 --local --silent
--fields-terminated-by=',' --lines-terminated-by='\r\n' --host=localhost 
maintable_usa t_dmu_history.txt

I'm running on Windows Vista, and mysqlimport is "Ver 3.7 Distrib 5.1.31, for 
Win32 (ia32)"

It runs for awhile, but I wind up with only one record:

localhost >select * from t_dmu_history;
+------------------+------------------+------------------------+
| t_dmu_history_id | DM_History_DM_ID | DM_History_Customer_ID |
+------------------+------------------+------------------------+
|                1 |            13071 |                   NULL |
+------------------+------------------+------------------------+
1 row in set (0.00 sec)

Obviously mysqlimport is parsing the input file incorrectly, but I don't know 
why.

Here's the table itself:

+------------------------+---------+------+-----+---------+----------------+
| Field                  | Type    | Null | Key | Default | Extra          |
+------------------------+---------+------+-----+---------+----------------+
| t_dmu_history_id       | int(11) | NO   | PRI | NULL    | auto_increment |
| DM_History_DM_ID       | int(11) | YES  | MUL | NULL    |                |
| DM_History_Customer_ID | int(11) | YES  | MUL | NULL    |                |
+------------------------+---------+------+-----+---------+----------------+

       Table: t_dmu_history
Create Table: CREATE TABLE `t_dmu_history` (
  `t_dmu_history_id` int(11) NOT NULL AUTO_INCREMENT,
  `DM_History_DM_ID` int(11) DEFAULT NULL,
  `DM_History_Customer_ID` int(11) DEFAULT NULL,
  PRIMARY KEY (`t_dmu_history_id`),
  KEY `DM_History_DM_ID` (`DM_History_DM_ID`),
  KEY `DM_History_Customer_ID` (`DM_History_Customer_ID`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8
