MySQL Error when importing CSV with empty fields I have CSV file with exported table, that has rows with fields that do not contain values. Columns are separated using "," and if fields have no values they look like that: ,,,,,, I tried to load data using following code:

LOAD DATA INFILE "C:/table.csv"
INTO TABLE target_table 
FIELDS TERMINATED BY ',' 
OPTIONALLY ENCLOSED BY '"'
LINES TERMINATED BY '\n'
IGNORE 1 ROWS


Columns in target table (to be loaded with data from this CSV file) are nullable, but server returns error:

"Incorrect integer value"


When I put NULL between commas in CSV file, server do not return any error. Is it possible to change some setting to have table loaded without changing the CSV file?
Something like this, checking every value for '', and inserting NULL instead, may help. Change a,b,c,d for the actual name and number of rows on the table:

$ cat /tmp/test.csv 
test1, test2, test3, test4
,,,
1,2,3,4
,,,

mysql&gt; LOAD DATA INFILE "/tmp/test.csv" INTO TABLE test.test  
          FIELDS TERMINATED BY ','  
          OPTIONALLY ENCLOSED BY '"' 
          LINES TERMINATED BY '\n' 
          IGNORE 1 ROWS 
       (@a, @b, @c, @d) 
       SET a = IF(@a = '', NULL, @a), 
           b = IF(@b = '', NULL, @b), 
           c = IF(@c = '', NULL, @c), 
           d = IF(@d = '', NULL, @d);

mysql&gt; SELECT * FROM test.test;
