如何更改标识符user_id的名称？ 变体不能在上面工作。 或者是否有选项sql。

public function eBL() { 
    $link_ebl = $this->config->address."?view=editprofile"; 
    $user_id = $this->data["id"]; 
    $name = $this->data["login"]; 
    if ($name == "") return $this->returnMessage("EMPTY_FIELD", $link_ebl); 
    $result = $this->article->setName($user_id, $name); 
    if ($result) return $this->returnPageMessage("SUCCESS_LOGIN", $this->config->address."?view=message"); 
    else return $this->unknownError($link_ebl); 
} 

public function setName($user_id, $name){ 
    return $this->setFieldOnID("user_id", "name", $name); 
}

如果你想改变你应该使用ALTER TABLE列名（假设列更改名称是INT）

ALTER TABLE your_table_name CHANGE user_id your_new_name INT;
