錯誤，當使用createEntityTables

Question

我得到這個錯誤，當我包括 $ installer-> createEntityTables（$ this-> getTable（'red/red'））;

我正在使用企業1.11 我也看到了替代方案是每種東西都非常耗時。有人可以告訴我該讓這個功能起作用嗎？

這是一個錯誤被觸發的問題，當它不應該被觸發時。長話短說，MySQL不支持DDL事務，並且在方法過程中在SQL中找到DDL例程並引發錯誤。

最簡單的答案是，註釋掉該行：

---

的lib /瓦瑞恩/ DB /適配器/ PDO/Mysql.php

protected function _checkDdlTransaction($sql) 
{ 
    if (is_string($sql) && $this->getTransactionLevel() > 0) { 
     $startSql = strtolower(substr(ltrim($sql), 0, 3)); 
     if (in_array($startSql, $this->_ddlRoutines)) { 
      // comment this out: trigger_error(Varien_Db_Adapter_Interface::ERROR_DDL_MESSAGE, E_USER_ERROR); 
     } 
    } 
} 

這樣做使你的模塊安裝。顯然黑客核心文件是一個可怕的想法。您應該擴展該方法或允許SQL運行，然後將生成的SQL轉換爲Magento MySQL API，如核心SQL安裝腳本中所示。後者是一個主要的痛苦..更好的想法是擴展該方法。
