csv file with fields having commas in them

I have a CSV file with fields given as follows.

number1, string1, "string2, string3", number2, string4, "string5, string6"

where number's are numbers and string's are strings. I am trying to read this as follows, I am ignoring first header line

LOAD DATA LOCAL 
  INFILE 'filename.csv' 
  INTO TABLE table_name 
  FIELDS TERMINATED BY ','  
  IGNORE 1 LINES;

But due to embedded commas in some fields, this command is giving causing to
overlap the fields. How would I correctly do this in MySQL?

You just need to add OPTIONALLY ENCLOSED BY '"':

LOAD DATA INFILE 'filename.csv' INTO TABLE table_name 
  FIELDS TERMINATED BY ',' 
  OPTIONALLY ENCLOSED BY '"'
  IGNORE 1 LINES;

File:

n1,s1,s23,n2,s4,s56
1,string1,"str2,str3",2,string4,"str5, str6"

Table and test:

mysql> create table tbl_name ( 
                               n1 integer, 
                               s1 varchar(10), 
                               s23 varchar(10),
                               n2 integer, 
                               s4 varchar(10), 
                               s56 varchar(10) 
                               );
Query OK, 0 rows affected (0.06 sec)

mysql> LOAD DATA INFILE 'c:\\temp\\data.txt' INTO TABLE tbl_name
    ->   FIELDS TERMINATED BY ','
    ->   OPTIONALLY ENCLOSED BY '"'
    ->   IGNORE 1 LINES;
Query OK, 1 row affected (0.01 sec)
