I am trying to add a new integer "id" column in a table of my database to map every row with an id. In order to do so, I am using a migration in Laravel 5.1. The run() function of the migration is exactly the following:

public function up()

 Schema::table('license_keys', function($table) 
 $table->integer('id_nuevo');
 );

The table I am trying to modify is set with default 'updated_at' and 'created_at' timestamps.

I execute the migration and the column is added correctly. I made sure to add the new column in the $fillable variable in my model. The next step in the process is to set the ids correctly, because that column is created with all 0s. In order to do so, I am using a Seeder with the following code:

public function run()

 $i=1;
 $licenses = LicenseKey::getEveryLicenseKey();
 foreach ($licenses as $license)
 $license->id_nuevo = $i;
 //$license->timestamps = false;
 $license->save();
 $i++;
 

But the problem starts here. When I try to update any field of any row with the save() function it gives me the following error:

[IlluminateDatabaseQueryException] 
 SQLSTATE[21S01]: Insert value list does not match column list: 1136 Column count doesn't match value count at row 1 (SQL: update `license_keys` set `id_nuevo` = 1, `updated_at` = 2018-11-15 13:24:11 
 where `hash_key` = 0...0b) 



 [PDOException] 
 SQLSTATE[21S01]: Insert value list does not match column list: 1136 Column count doesn't match value count at row 1

But if I set the timestamps to false (commented line in the code), the operation succeeds. Even if I try to manually change the value of the 'updated_at' column in phpMyadmin, it gives me the same error. Can anybody help me with this problem?

The structure of the table is:

CREATE TABLE `license_keys` (
`hash_key` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
`user_id` int(10) UNSIGNED NOT NULL,
`plan_id` int(10) UNSIGNED NOT NULL,
`id_nuevo` int(11) NOT NULL,
`max_credits` bigint(20) NOT NULL,
`max_models` int(11) NOT NULL,
`max_model_categories` int(11) NOT NULL,
`max_dictionaries` int(11) NOT NULL,
`max_dictionary_entries` int(11) NOT NULL,
`max_sentiment_models` int(11) NOT NULL,
`max_sentiment_entries` int(11) NOT NULL,
`current_credits` bigint(20) NOT NULL,
`current_requests` bigint(20) NOT NULL,
`last_operation` timestamp NULL DEFAULT NULL,
`total_credits` bigint(20) NOT NULL,
`total_requests` bigint(20) NOT NULL,
`msg_pay_status` varchar(510) COLLATE utf8_unicode_ci NOT NULL,
`start_date` timestamp NULL DEFAULT NULL,
`start_billing_date` timestamp NULL DEFAULT NULL,
`expiration_date` timestamp NULL DEFAULT NULL,
`update_operation` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
`created_at` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,,
`updated_at` timestamp NULL DEFAULT CURRENT_TIMESTAMP
 ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

And the query I'm trying to execute is:

update `license_keys` set `id_nuevo` = 1, `updated_at` = '2018-11-15 13:24:11' where `hash_key` = '0...0b'

Thanks.

Try your query without update_at, it will be written automatically

update `license_keys` set `id_nuevo` = 1 where `hash_key` = '0...0b'
