执行查询时,我总是遇到此错误:

您的SQL语法有错误; 检查与MySQL服务器版本对应的手册,以便在第1行'read = 1 WHERE user_id_sender = 1 AND user_id_receiver = 33 AND OR user_id_sender'附近使用正确的语法

这是我的查询:

mysql_query("UPDATE messages SET read =1 WHERE user_id_sender = $user_id AND user_id_receiver = $user_id_partner AND read = 0 OR user_id_sender = $user_id_partner AND user_id_receiver = $user_id  AND read = 0  ") or die (mysql_error());

在table(messages)具有这些列:

message_id(INT)(AI)
user_id_sender(INT)
user_id_receiver(INT)
message(TEXT)
read(INT)

我真的不知道它为什么这样做,我看了网络但我似乎无法找到我的确切问题的答案.也许有人可以帮助我.
