Question

这是我的迁移脚本

Schema::create('orders', function (Blueprint $table) {
            .
            .
            .
            $table->decimal('coupon_discount')->default(0);
            $table->decimal('delivery_charge')->default(0);
            $table->decimal('sub_total')->default(0);
            $table->decimal('total')->storedAs('(sub_total + delivery_charge) - coupon_discount');
            $table->decimal('paid')->default(0);
            $table->decimal('due')->storedAs('total - paid');
            $table->longText('note')->nullable();
            .
            .
            .
            $table->timestamps();
        });

我必须为总数列和到期列创建generated-columns。

但是当我尝试运行迁移文件时，它显示异常

例外：

)

注意：我有 mysql Ver 15.1 Distrib 10.1.35-MariaDB，用于Win32

我错过了什么？

[已解决]

这是我的MariaDB版本问题，而不是PHP

将MariaDB 10.1升级到10.3。现在工作正常。
