Multiple possibilities for LINES TERMINATED BY and FIELDS TERMINATED BY - MySQL
Try LINES TERMINATED BY '\r\n'
This will work for files ending lines with '\r\n', but also with '\r' and '\n'. From the MySQL docs:
The FIELDS TERMINATED BY, LINES STARTING BY, and LINES TERMINATED BY values can be more than one character. For example, to write lines that are terminated by carriage return/linefeed pairs, or to read a file containing such lines, specify a LINES TERMINATED BY '\r\n' clause.
[EDITED]
You also need to add \r\n
to the clause FIELDS TERMINATED BY
in order to tell the parser not to include the end-of-lines symbols in the last field of the first line. So
FIELDS TERMINATED BY ';, \t\r\n'
will work in most cases.

I'm trying to create a feature in my Content Management System in which users can upload a CSV file which is then parsed and the data is put in a MySQL database. To do this I use a file input and this SQL query.
$sql = "LOAD DATA LOCAL INFILE '".$_FILES["file"]["tmp_name"]."' INTO TABLE persons FIELDS TERMINATED BY ';' LINES TERMINATED BY '\r' (id, name, email, contacts)";
This works perfectly for a
.csv
file I created on my computer, but not al CSV files have fields that are terminated by a semicolon and have lines that are terminated with a\r
. Now I want this query to work for all.csv
files. Otherwise this feature won't work well enough to be implemented in my CMS. Is there any way I can make this work for.csv
files which have other field and line endings? (e.g \n, \r\n, ,) -
Admin over 9 yearsThanks for your answer! Both solutions you give don't seem to work though. Any idea why that is?

Al_ over 9 yearsYou are right. I've amended the answer. I think the problem is in the clause
FIELDS TERMINATED BY

Admin over 9 yearsSadly, this doesn't seem to work either. Thanks for your effort though!

Al_ over 9 yearsWell, this solution will work well with files of the type '\r\n' and '\n' (which are the majority). Problem is with files of the type '\r'. I'd suggest to get rid of '\r', for example with
dos2unix
(system command) before running the sqlLOAD DATA
