Hi All, Just wanted to say that using LOAD DATA INFILE worked perfectly, upload is not instantaneous! Thank you. I had to fight appArmor for most of the morning, but now I finally found a way to let mysql read into /var/www. That made me wonder, and bear mind that I very new at this: on a production server, is default for mysql to have access to the website basedir or do I have to use something like LOAD LOCAL DATA INFILE? Thanks! T.
