在 Laravel 9 中执行数据库迁移，修改字段名称，再修改其属性，报错：There is no column with name inbounded_quantity on table return_order_items.
1、在 Laravel 9 中执行数据库迁移，修改字段名称，再修改其属性，报错：There is no column with name inbounded_quantity on table return_order_items.如图1

2、代码实现如下
1 2 3 4 | Schema::table('return_order_items', function (Blueprint $table) { $table->renameColumn('received_quantity', 'inbounded_quantity'); $table->unsignedInteger('inbounded_quantity')->nullable()->default(0)->comment('已入库数量')->change();}); |
3、决定尝试先修改其属性，再修改字段名称。代码实现如下
1 2 3 4 | Schema::table('return_order_items', function (Blueprint $table) { $table->unsignedInteger('received_quantity')->nullable()->default(0)->comment('已入库数量')->change(); $table->renameColumn('received_quantity', 'inbounded_quantity');}); |
4、再次执行数据库迁移，执行成功。但是，查看表设计，发现字段注释未修改，不符合预期。如图2

5、由于此字段还未使用到，仅是之前预留的，最后决定先删除字段，再添加字段。代码实现如下
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 | <?phpuse Illuminate\Database\Migrations\Migration;use Illuminate\Database\Schema\Blueprint;use Illuminate\Support\Facades\Schema;return new class extends Migration{ /** * Run the migrations. * * @return void */ public function up() { Schema::table('return_order_items', function (Blueprint $table) { $table->dropColumn('received_quantity'); $table->unsignedInteger('inbounded_quantity')->default(0)->comment('已入库数量')->after('return_quantity'); $table->unsignedInteger('signed_quantity')->default(0)->comment('已签收数量'); }); } /** * Reverse the migrations. * * @return void */ public function down() { Schema::table('return_order_items', function (Blueprint $table) { $table->dropColumn('inbounded_quantity'); $table->unsignedInteger('received_quantity')->nullable()->comment('已收货数量')->after('return_quantity'); $table->dropColumn('signed_quantity'); }); }}; |
6、执行迁移后，表结构符合预期。如图3
