PHP/MySQL - "BEGIN ... COMMIT"不工作

Question

我正在寻找一种方法,在一个查询中将数据插入到两个数据库表中,如果一个失败,既不保存(我不想要孤立的数据).我遇到了一个Stack Overflow问题,它向我展示了如何使用BEGIN ... COMMIT来实现这一目标,但它根本无法正常工作.

这是我设置的查询:

$query = "BEGIN;
            INSERT INTO content_subpages (title, url_referer) VALUES ('$pagetitle','$url_referer');
            INSERT INTO ccm_main_menu (sub_item, sub_item_link,sub_item_sort_order) VALUES ('$pagetitle','$url_referer','$newsort');
            COMMIT;";
mysql_query($query) or die (mysql_error());

我收到以下错误: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'INSERT INTO content_subpages (title, url_referer) VALUES ('TESTING','testing'); ' at line 2

这是我第一次使用BEGIN ... COMMIT,所以我可能做错了是合理的,但是我遵循了我提到的Stack Overflow问题的选定答案给出的SQL Fiddle示例的语法(http:// stackoverflow.com/questions/12649706/mysql-insert-into-multiple-tables-in-same-query-with-begincommit),但它仍然无法正常工作.

如果我可以在没有BEGIN ... COMMIT的情况下轻松实现"全有或全无"的多个INSERT结果,那将是一个可接受的解决方案.

提前致谢

尝试将这些行分成多个php语句:

$query = "BEGIN";
mysql_query($query) or die (mysql_error());
$query = "INSERT INTO content_subpages (title, url_referer) VALUES ('$pagetitle','$url_referer')";
mysql_query($query) or die (mysql_error());

$query = "INSERT INTO ccm_main_menu (sub_item, sub_item_link,sub_item_sort_order) VALUES ('$pagetitle','$url_referer','$newsort')";
mysql_query($query) or die (mysql_error())

$query = "COMMIT";
mysql_query($query) or die (mysql_error());
