1、参考网址：http://www.shuijingwanwq.com/2019/08/15/3427/
UPDATE `cpa_channel_app_source`, `cpa_weibo_weibo_connect_web_app_user` SET `cpa_channel_app_source`.`permission` = `cpa_weibo_weibo_connect_web_app_user`.`permission` WHERE `cpa_channel_app_source`.`id` = `cpa_weibo_weibo_connect_web_app_user`.`channel_app_source_id`;
2、更新表：channel_app_source 中的字段：permission 的值为：3，如图1
3、基于数据库迁移命令，生成如上所示的一条 SQL 的实现，编辑 \console\migrations\m190815_020034_permission.php
<?php
use yii\db\Expression;
use yii\db\Migration;
/**
* Class m190815_020034_permission
*/class m190815_020034_permission extends Migration
{
/**
* {@inheritdoc}
*/ public function safeUp()
{
$this->update('{{%channel_app_source}}, {{%weibo_weibo_connect_web_app_user}}', ['{{%channel_app_source}}.permission' => new Expression('{{%weibo_weibo_connect_web_app_user}}.permission')], ['{{%channel_app_source}}.id' => new Expression('{{%weibo_weibo_connect_web_app_user}}.channel_app_source_id')]);
}
/**
* {@inheritdoc}
*/ public function safeDown()
{
echo "m190815_020034_permission cannot be reverted.\n";
return false;
}
/*
// Use up()/down() to run migration code without a transaction.
public function up()
{
}
public function down()
{
echo "m190815_020034_permission cannot be reverted.\n";
return false;
}
*/}
4、执行数据库迁移命令，如图2
PS E:\wwwroot\channel-pub-api> ./yii migrate
Yii Migration Tool (based on Yii v2.0.15.1)
Total 1 new migration to be applied:
m190815_020034_permission
Apply the above migration? (yes|no) [no]:yes

5、查看表：channel_app_source 中的字段：permission 的值为：2，符合预期，如图3
