LOAD DATA LOCAL INFILE loading one record only

In MySQL I use LOAD DATA LOCAL INFILE like this:

LOAD DATA LOCAL INFILE 'code.csv' 
INTO TABLE MyDB.code FIELDS TERMINATED BY ',' 
ENCLOSED BY '"' LINES TERMINATED BY '\r\n' (code_id,code_name,code_date);

I get a response like this:

Query OK, 1 row affected, 2 warnings (1.80 sec) Records: 665893 Deleted: 0 Skipped: 665892 Warnings: 1

I am using Ubuntu and MySQL is running on localhost. What is causing LOAD DATA LOCAL INFILE command to skip these records?

If you have any unique constraints on your table then LOAD DATA command will skip the rows which violate that constraint.

An illustration of the problem here: https://stackoverflow.com/a/20913896/445131

To fix it, either remove the unique constraint on that table, or remove the rows that are violating that constraint in the text file.

Have your verified the lines are actually terminated by \r\n? Also, have you exported PROPER CSV, or just comma-delimitation? If your values are not properly quoted (as you've specified), that could also lead to an import issue.

You may want to try and removing the line-break specification:

LOAD DATA LOCAL INFILE 'code.csv' INTO TABLE MyDB.code FIELDS TERMINATED BY ',' ENCLOSED BY '"' (code_id,code_name,code_date);
