MySQL File Access

June 4, 2018

MySQL out of the box doesn’t permit access to the local file system e.g. for table import or export operations. Quickest fix for this that I found was to run the server from the command line as follows:

mysqld --secure-file-priv=/Users/me/tmp

I can then use statements such as

load data infile '~/tmp/data.csv' fields terminated by ',' 
ignore 1 lines (field1,field2,@field3) set field3=somefunction(@field3);


select field1,field2,someotherfunction(field3) from sometable into
outfile '~/tmp/outdata.dsv' terminated by '|';
