Question

我有以下迁移，我在表格中添加了一个额外的列：

<?php

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class AddTenantIdToPeopleTable extends Migration
{
    public function up()
    {
        /*
        * Need to create the column as null and then mark it as non-null to
        * avoid SQLite problem General error: 1 Can not add to NOT NULL column with default value NULL
        */

        Schema::table('people', function (Blueprint $table) {
            $table->integer('tenant_id')->nullable()->unsigned();
            $table->index('tenant_id');
        });

        Schema::table('people', function (Blueprint $table) {
            $table->integer('tenant_id')->nullable(false)->change();
        });
    }

    public function down()
    {
        Schema::disableForeignKeyConstraints();
            Schema::table('people', function (Blueprint $table) {
                $table->dropColumn('tenant_id');
            });
        Schema::enableForeignKeyConstraints();
    }
}

我可以使用PostgreSQL，SQLite和MySQL运行此迁移而没有任何错误，但是当我尝试使用Maria DB运行时，会发生以下错误：

Error

我尝试了一些东西，但没有任何作用。

我设法让这件事发挥作用。我刚刚添加了＆＃34; - ＆gt;默认（null）＆＃34;

我这样做了：

public function up()
    {
        Schema::table('people', function (Blueprint $table) {
            $table->integer('tenant_id')->nullable()->unsigned();
            $table->index('tenant_id');
        });

        Schema::table('people', function (Blueprint $table) {
            $table->integer('tenant_id')->nullable(false)->default(null)->change();
        });
    }

错误NULL DEFAULT NULL使用MariaDB进行Laravel迁移
