爲什麼不能處理這個查詢？（mysql，php）

Question

我在使用mysql時遇到一些問題。而我完全不知道！

這問題是...

$sql = "insert into Write_Member_Comment(writer, passwd, commentID) 
        values('test', '$passwd' '$commentID')"; 


mysql_query($sql, $connect); 
echo mysql_error(); 

我暫時填補作家 '測試'（orginally這是 '$作家'），但結果是...

'Column count doesn't match value count at row 1' 

這裏的我的Write_Member_Comment表。

create table Write_Member_Comment(
writer  char(30) not null, 
passwd  char(30) not null, 
commentID int not null, 
FOREIGN KEY (commentID) REFERENCES PostComment(commentID) ON DELETE CASCADE ON UPDATE CASCADE) engine=InnoDB character set=utf8; 

爲什麼不工作？

你缺少一個逗號，它應該是：

$sql = "insert into Write_Member_Comment(writer, passwd, commentID) 
       values('test', '$passwd', '$commentID')";
