Php 错误：SQLSTATE[42000]：语法错误或访问冲突：1064您的SQL语法有错误；

我想使用laravel迁移我的数据库。
我尝试以下命令：

php-artisan-migrate:fresh--seed

并接受以下错误：

以下是我的

2019\u 10\u 28\u 130723\u alter\u users\u表

迁移文件的内容：

---

此行会导致迁移出错

$table->unsignedBigInteger('deductible_amount')->change();

试着把它改成

$table->string('deductible_amount')->unsigned()->change();

针对您的情况更新答案

        Schema::table('users', function (Blueprint $table) {
            $table->unsignedBigInteger('deductible_amount_new');
        });

        DB::statement('UPDATE `users` SET deductible_amount_new=deductible_amount ');

        Schema::table('users', function (Blueprint $table) {
            $table->renameColumn('active', 'is_active');
            $table->dropColumn([
                                    'settings',
                                    'google_id',
                                    'github_id',
                                    'telegram_notif',
                                    'income',
                                    'email_notif',
                                    'sms_notif',
                                    'temppass',
                                    'storm_id',
                               ]);
            $table->dropColumn('deductible_amount');
            $table->softDeletes();
        });

        Schema::table('users', function (Blueprint $table) {
            $table->renameColumn('deductible_amount_new', 'deductible_amount');
        });

我希望它能有所帮助。
该行位于ˋdown`方法上，将在rollback命令中触发。我知道问题出在“免赔额”字段上，但在
up
方法上，因为我正在尝试
php artisan migrate
commanr。你在说什么？该行在代码中的
up
方法上，尝试将类型更改为
string
，问题将得到解决。稍后谢谢。对不起，这是从另一个错误答案复制的评论，该用户已将其删除。但我需要这个字段是整数，因为它存储的是整数，而不是字符串。这个答案甚至没有解释。
