我在这里有这段代码,我有一个模棱两可的错误
if (Database.Query(ref reader, "SELECT fromID, toID, status, accountStatus, name FROM friends LEFT JOIN phpbb_users ON ( (user_id = toID) OR (user_id = fromID) ) AND (user_id != " + userID + ") WHERE (fromID=" + userID + " OR toID=" + userID + ")") == false)
{
return null;
}
有什么帮助吗?
