How to LOAD DATA INFILE in mysql with first col being Auto Increment?

Question

Currently, We have a table similar to this:

---------------------
ID | AField | BField|
---------------------

The ID is Auto Increment

Answer 1

LINES TERMINATED BY '\r\n' 

That was the key to success for me when using a text file

Answer 2

If you have only a small number of columns, you can just name them: LOAD DATA LOCAL INFILE 'myfile.txt' INTO TABLE mytable (AField); (assuming only ID & AField)

Answer 3

Try to use NULL as the value in the csv file for the ID field.

Answer 4

LOAD DATA INFILE '/tmp/data.csv'
INTO TABLE your_table
FIELDS TERMINATED BY ',' LINES TERMINATED BY '\r'
(AField, BField);

Answer 5

The best thing to do is just include the 2 non-auto-increment columns in the CSV, and then explicitly set the ID column to NULL in the load data infile statement.

Something like this:

LOAD DATA INFILE '/tmp/data.csv'
INTO TABLE your_table
FIELDS TERMINATED BY ','
(AField, BField)
SET ID = NULL;

Answer 6

NULL in CSV file is read as a STRING in MySQL. If you want to have null values in a MySQL column instead use \N in place of `NULL. This will fix the issue and you will get the required result.
