Question

升级到Laravel 5.4和MySQL 5.7时，迁移不再起作用，我收到此错误：

[Illuminate\Database\QueryException]
  SQLSTATE[42000]: Syntax error or access violation: 1067 Invalid default value for 'updated_at' (SQL: create table `tracker_paths` (`id` bigint unsigned not null auto_increment primar
  y key, `path` varchar(255) not null, `created_at` timestamp not null, `updated_at` timestamp not null) default character set utf8mb4 collate utf8mb4_unicode_ci engine = InnoDB ROW_FO
  RMAT=DYNAMIC) (SQL: SQLSTATE[42000]: Syntax error or access violation: 1067 Invalid default value for 'updated_at' (SQL: create table `tracker_paths` (`id` bigint unsigned not null a

  gine = InnoDB ROW_FORMAT=DYNAMIC))

我该怎么办？

Answer 1

这是由于sql模式STRICT_TRANS_TABLES，所以你有三个选择：

1）修复您的迁移。

2）在mysql连接中将strict更改为false：

'mysql' => $database = [
    ...
    'strict' => false,
    ...
],

将禁用所有这些sql模式：

set session sql_mode='ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'

3）设置自定义模式，删除STRICT_TRANS_TABLES

'mysql' => $database = [
    ...
    'modes' => "set session sql_mode='ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'",
    ...
],

＆＃39;列＆＃39;的默认值无效。
