我正面临一个令我疯狂的奇怪问题。我从来没有碰到这样的事情。即使我可以预测这将是非常容易的事情，但我在看它。
我正在基于业务角色逻辑执行查询。所以在某些情况下我会选择并更新，在其他情况下我会做一个选择，更新，然后插入所以第四个。以下是我处理代码的整体结构
Open PDO connection
1 getDataSet 1 (select)
2 ProcessQuery (update)
3 getDataSet 1 (select)
4 ProcessQuery (Insert)
Close PDO connection by setting the PDO object to null.
由于奇怪的原因，插入根本不起作用！选择工作，更新工作没有问题但是当涉及到插入部分它不起作用。它根本不会给我任何错误。实际上，我复制了相同的查询并在phpMyAdmin中执行它并且查询有效！
我应该注意到我要插入的表非常大，并且有超过400万条带有许多索引的记录。
可能是什么问题？我还能检查什么？为什么插入不是从脚本工作，它是从phpmyadmin ??

这是我的实际代码，不插入记录
感谢您的帮助：）
PS 这是我的代码中不会运行的查询，但是当我在PHPmyadmin
中运行它时它会运行INSERT INTO phone_calls (account_id, call_code_id, trigger_on, created_on, call_subject, status, last_call_id , call_direction, owner_id, workflow_generated, call_notes) VALUES(11601, 1, "2013-04-11 16:36:00", NOW(), "Initial Development attempt: 1", 1, 17132, "OUTBOUND", 1, 1, "");
答案 0 :(得分：0)
可能是什么问题？我还能检查什么？为什么插入不能从脚本工作，它是从phpmyadmin工作？
欢迎来到程序员的话 事实上，编程不只是编写代码 但是，不幸的是，程序员花了50％的时间来回答上面提到的问题。这不是一件容易的事。必须付出相当大的努力。坏消息，这样的问题几乎无法在Q＆amp; A网站上找到答案。你自己回答了什么？所以，你自己的手是你的最后手段。这样卷起袖子开始调试：
@，try..catches和零错误报告来解决这些错误。
