SQLSTATE [HY000]：一般錯誤

Question

當我嘗試獲取數據庫表的備份時，我正面臨上述錯誤問題。請檢查

$table_name = "back_up_manager"; 
$backup_file = "/var/www/html/solaris_dev/uploads/back_up_manager".date('F h:i:s').".csv"; 
$sql = "SELECT * INTO OUTFILE '$backup_file' FROM $table_name"; 
$command = Yii::$app->db->createCommand($sql)->queryAll(); 

Answer 1

暢的代碼

$sql = "SELECT * INTO OUTFILE '" . $backup_file. "' FROM " .$table_name; 

這一部分在您的例子$sql變量包含文件的路徑無效。
