我正在尝试运行一个在Laravel 5.2版本上完全正常运行的迁移,但是当我尝试在laravel 5.5上运行它时出现错误:
在Connection.php第664行:
SQLSTATE [42000]:语法错误或访问冲突:1067无效 ' to_date'的默认值(SQL:create table
transactions
(id
int unsigned not null auto_increment主键,user_id
int unsigned not null,vehicle_id
int unsigned not null,from_date
t
imestamp不为空,to_date
时间戳不为空,flight_number
varchar(255)not null,created_at
timestamp null,updated_at
ti
mestamp null)默认字符集utf8mb4 collate utf8mb4_unicode_ci)在Connection.php第458行: SQLSTATE [42000]:语法错误或访问冲突:1067无效 ' to_date'
的默认值
这是该表的迁移:
<?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateTransactionsTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('transactions', function (Blueprint $table) {
$table->increments('id');
$table->integer('user_id')->unsigned();
$table->foreign('user_id')->references('id')->on('users');
$table->integer('vehicle_id')->unsigned();
$table->foreign('vehicle_id')->references('id')->on('vehicles');
$table->timestamp('from_date');
$table->timestamp('to_date');
$table->string('flight_number');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::drop('transactions');
}
}
为什么在使用5.2版本时不能使用新版本的laravel?
答案 0 :(得分:2)
我发现导致此问题的原因是, laravel 5.5 MySQL 严格模式已在 laravel config database.php
文件中启用默认情况下,通过将模式设置为'strict' => false
,就像在版本5.3中一样,我可以运行迁移。
