I've got a CSV file with 11 columns and I have a MySQL table with 9 columns.

The CSV file looks like:

col1, col2, col3, col4, col5, col6, col7, col8, col9, col10, col11

and the MySQL table looks like:

col1, col2, col3, col4, col5, col6, col7, col8, col9

I need to map the columns 1-8 of CSV file directly to the first 8 columns of the MySQL table. I then need to skip the next two columns in the CSV file and then map column 11 of CSV file to column 9 of MySQL table.

At the moment I am using the following SQL command:

LOAD DATA LOCAL INFILE 'filename.csv' INTO TABLE my_table
FIELDS TERMINATED BY ','
ENCLOSED BY ''
LINES TERMINATED BY '\n'

But the above code maps the first 9 columns of CSV file to the 9 columns in the MySQL table.

From Mysql docs:

You can also discard an input value by assigning it to a user variable and not assigning the variable to a table column:

LOAD DATA INFILE 'file.txt'  
INTO TABLE t1 (column1, @dummy, column2, @dummy, column3);

FYI: I had to add the `(column1, @dummy, column2...` field statement to the end of my example SQL. Initially I had added it directly after the table name as shown the above example but I kept getting a MySQL error.
