    You are going to have to provide more information. Such as, what is the first few lines of the CSV file? What did you expect to happen when you ran that query? What happened instead? – cdhowie Nov 10 '10 at 11:27

Not a problem. You can specify which CSV column gets imported into which database column.

LOAD DATA INFILE syntax

By default, when no column list is provided at the end of the LOAD DATA INFILE statement, input lines are expected to contain a field for each table column. If you want to load only some of a table's columns, specify a column list:

LOAD DATA INFILE 'persondata.txt' INTO TABLE persondata (col1,col2,...);

What I like to do when I find the INFILE syntax too complicated is use a graphical client like HeidiSQL to click together the proper column order (it has a graphical preview) and copy+paste the generated SQL query.

You can create a script to parse your csv file and to put the data into db.

Something like:

    $path = "yourfile.csv";
    $row = 1;
    if (($handle = fopen($path, "r")) !== FALSE) {
        while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
            $row++;
            $data_entries[] = $data ;

        }
        fclose($handle);
    }
    // this you'll have to expand
    foreach($data_entries as $line){
        $sql = "INSERT INTO ..."
        $db->execute($line);
    }

  • ..i ran into this problem and i found your answer..can you plz tell me what is this $row doing..? as my $data returns only the single rows value. thanks – Criesto Jan 09 '14 at 09:48
  • I guess is not doing anything in here... probably I left it in while cleaning up real code to make this example – Elzo Valugi Jan 10 '14 at 14:04
  • So, would you be kind enough to write the complete code plz..? – Criesto Jan 13 '14 at 13:14

If you want to load only the first 7 characters of the last column from the CSV file into the uniqComments column of the table, then you can do something like this...

load data local infile 'uniq.csv' into table tblUniq fields terminated by ',' 
enclosed by '"' lines terminated by '\n' (uniqName, uniqCity, @seven_chars) 
set uniqComments=left(@seven_chars,7)

Try this, this is working fine for me.

ini_set('auto_detect_line_endings',TRUE);

$csv_data=array();

$file_handle = fopen($_FILES['file_name']['tmp_name'], 'r');

while(($data = fgetcsv($file_handle) ) !== FALSE){

 $update_data= array('first'=>$data['0'],
                      'second'=>$data['1'],
                      'third'=>$data['2'],
                       'fourth'=>$data['34']);

// save this array in your database
}

I created the table with the following MySQL query,

create table sales(row_id int not null, order_id varchar(20),order_date DATE, ship_mode varchar(30),customer_id varchar(10), customer varchar(15),segment varchar(30),profit double(10,4));

Then I checked with following MySQL query,

mysql> show columns from sales;
+-------------+--------------+------+-----+---------+-------+
| Field       | Type         | Null | Key | Default | Extra |
+-------------+--------------+------+-----+---------+-------+
| row_id      | int          | NO   |     | NULL    |       |
| order_id    | varchar(20)  | YES  |     | NULL    |       |
| order_date  | date         | YES  |     | NULL    |       |
| ship_mode   | varchar(30)  | YES  |     | NULL    |       |
| customer_id | varchar(10)  | YES  |     | NULL    |       |
| customer    | varchar(15)  | YES  |     | NULL    |       |
| segment     | varchar(30)  | YES  |     | NULL    |       |
| profit      | double(10,4) | YES  |     | NULL    |       |
+-------------+--------------+------+-----+---------+-------+

Then I checked SQL mode with the following query,

mysql> SHOW VARIABLES LIKE 'sql_mode';

Answer was

+---------------+--------------------------------------------+
| Variable_name | Value                                      |
+---------------+--------------------------------------------+
| sql_mode      | STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION |
+---------------+--------------------------------------------+

Then I changed it as follows,

SET SQL_MODE='';

Then finally run following SQL query to load data from CSV into the table,

mysql> load data infile "C:/ProgramData/MySQL/MySQL Server 8.0/Uploads/sales_data.csv" into table sales fields terminated by ','lines terminated by '\r\n' ignore 1 rows;

It worked for me but save CSV file into C:/ProgramData/MySQL/MySQL Server 8.0/Uploads/
