laravel - Laravel Drop 重命名索引

Question

我用 laravel 创建了一个索引index()

$table->index(['group_tasks_outline_agreement_uuid'], 'gt_oa_uuid');

我已尝试删除此 idexdropIndex()

$table->dropIndex(['group_tasks_outline_agreement_uuid']);
or
$table->dropIndex(['gt_oa_uuid']);

它显示错误消息：语法错误或访问冲突：1091 Can't DROP INDEX hps_purchase_order_hps_purchase_order_uuid_index; 检查它是否存在

Answer 1

它应该是 $table->index(['group_tasks_outline_agreement_uuid'], 'group_tasks_outline_agreement_gt_oa_uuid_index');
