merge multiple fields of csv file while running mysqlimport command

I have a mysql table like this +----------------+--------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +----------------+--------------+------+-----+---------+----------------+ | id | int(11) | NO | PRI | NULL | auto_increment | | roll_no | varchar(50) | NO | MUL | NULL | | | marks | varchar(100) | YES | | NULL | | | academy | varchar(100) | YES | | NULL | | +----------------+--------------+------+-----+---------+----------------+ the marks column can have multiple numbers separated by comma like this 45,67,78,80, # First Example 34,56, # Second Example I have to run mysqlimport command such that the fields after the first fields till second-last fields should merge into marks column I tried something like this mysqlimport --fields-terminated-by=, --columns='roll_no, marks, academy' --ignore --local -u root -pxxxx result results.csv But extra fields (after 3rd one) gets truncated. How to handle such scenarios where the csv fields are dynamic
