LOAD DATA LOCAL INFILE from fputcsv: data not recorded

I have below CSV file: (3 columns)

998877665544331,,baba
998877665544332,,
998877665544333,,
998877665544334,,test
998877665544335,,
,R32AS00ZZYY,
998877665544337,,
998877665544338,,
998877665544339,,asfd
998877665544330,,
,R32AS00XXYY,
,R32AS00XXZZ,

I store it as file by: fputcsv($fp, array($data0, $data1, $data2));

then i want to store it in DB with this query:

$query = sprintf(
        "LOAD DATA LOCAL INFILE '%s' 
        INTO TABLE devices 
        FIELDS TERMINATED BY ','
        OPTIONALLY ENCLOSED BY '\"' 
        LINES TERMINATED BY '\\n'
        (col0, col1, col2);", addslashes(storage_path('app/file.csv')));

$asdf = DB::connection()->getpdo()->exec($query);

problem/question:

  1. why it only store first record and 6th record? like below:

    +--+----------------+-------------+--------+------+
|id| col0           | col1        | col xx | col2 |
+--+----------------+-------------+--------+------+
|01|998877665544331 | ""          | NULL   | baba |
|02| ""             | R32AS00ZZYY | NULL   | ""   |
+--+----------------+-------------+--------+------+

what I try to achieve: stored all of data accordingly

EDIT: my table definition:

/*Table structure for table `tabel_name` */

DROP TABLE IF EXISTS `tabel_name`;

CREATE TABLE `tabel_name` (
  `id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,
  `col0` VARCHAR(16) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
  `col1` VARCHAR(12) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
  `colxx` VARCHAR(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
  `col2` VARCHAR(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
  `created_at` TIMESTAMP NULL DEFAULT NULL,
  `updated_at` TIMESTAMP NULL DEFAULT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `tabel_col0_unique` (`col0`),
  UNIQUE KEY `tabel_col1_unique` (`col1`)
) ENGINE=INNODB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;
Solution

  • You've defined col1 as unique:

      UNIQUE KEY `tabel_col1_unique` (`col1`)

    And your data has non-unique values:

    998877665544331,,baba
998877665544332,,

    So the first row gets inserted, but then the second fails because of the unique constraint.
