我正在尝试使用构建在 PDO 之上的 ORM 运行一个简单的查询。
这是我要运行的代码:
$message = ORM::for_table("messages")
->where("to_user_id", $user_id)
->where("deleted", 0)
->where("reply_id", $message_id)
->where("read", 0)
->order_by_desc("time")
->limit(1)
->count();
(这是使用 j4mie 的 Idiorm，https://github.com/j4mie/idiorm )
此代码似乎可行，但我收到以下 MySQL 错误:
Error: Uncaught exception 'PDOException' with message 'SQLSTATE[42000]:
Syntax error or access violation:
1064 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 'read = '0' ORDER BY time DESC LIMIT 1'

最佳答案
read 和time 是reserved words在 mySQL 中。
您必须重命名列，或在列名周围加上反引号:
->order_by_desc("`time`")
->where("`read`", 0)
(当然，前提是 ORM 允许这样做。)
