Yii2 querybuilder 正确语法 table 名称与原始 sql

Question

谁能告诉我我在这个声明中做错了什么

$connection =   Yii::$app->db;
$result=$connection->createCommand("SHOW TABLE STATUS LIKE 
                                   {{%promo_deliveries}}")->execute();

我遇到了这个错误

Exception 'yii\db\Exception' with message 'SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'sms_promo_deliveries' at line 1 The SQL being executed was: `SHOW TABLE STATUS LIKE sms_promo_deliveries'

in F:\xampp\htdocs\Nxb\sms_protected\vendor\yiisoft\yii2\db\Schema.php:631

Error Info: Array ( [0] => 42000 [1] => 1064 [2] => You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'sms_promo_deliveries' at line 1 )

Answer 1

这与使用查询生成器时的 table 命名约定无关，实际上这是指定的语法错误，必须在 table 名称周围添加引号，因为我正在使用LIKE 关键字匹配 table 名称。

$result=$connection->createCommand("SHOW TABLE STATUS LIKE 
                                   '{{%promo_deliveries}}'")->execute();
