我有下面的csv文件:(3列)
998877665544331,,baba
998877665544332,,
998877665544333,,
998877665544334,,test
998877665544335,,
,R32AS00ZZYY,
998877665544337,,
998877665544338,,
998877665544339,,asfd
998877665544330,,
,R32AS00XXYY,
,R32AS00XXZZ,
我将其存储为文件: fputcsv($fp, array($data0, $data1, $data2));
然后我想用以下查询将其存储在db中:
$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);
问题:
为什么它只存储第一个记录和第六个记录?如下所示:
+--+----------------+-------------+--------+------+
|id| col0 | col1 | col xx | col2 |
+--+----------------+-------------+--------+------+
|01|998877665544331 | "" | NULL | baba |
|02| "" | R32AS00ZZYY | NULL | "" |
+--+----------------+-------------+--------+------+
我尝试实现的是:相应地存储所有数据
编辑:我的表定义:
/*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;

您已将col1定义为unique:
并且您的数据具有非唯一值:
所以第一行被插入,但是第二行由于惟一约束而失败。
