为什么可以';t处理此查询?(mysql,php)


Why can't process this query?(mysql, php)

我在使用mysql时遇到了一些问题。我完全不知道!。

问题是…

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

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

我临时填写了作家"测试"(最初这是"$writer"),但结果是…

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

这是我的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;

为什么不工作?

您缺少一个逗号,它应该是:

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