For those who have the following error        Error Code  1290  The MySQL server is running with the   --secure-file-priv option so it cannot execute this statement   You can simply run this command to see which folder can load files from   SHOW VARIABLES LIKE  secure file priv     After that  you have to copy the files in that folder and run the query with LOAD DATA LOCAL INFILE instead of LOAD DATA INFILE

Specify the name of columns in the CSV in the load data infile statement   The code is like this   LOAD DATA INFILE   path filename csv  INTO TABLE table name FIELDS TERMINATED BY     LINES TERMINATED BY   r n   column name3  column name5     Here you go with adding data to only two columns you can choose them with the name of the column  to the table   The only thing you have to take care is that you have a CSV file filename csv  with two values per line row   Otherwise please mention  I have a different solution   Thank you
