Dreamweaver中应用mysql语句遇到的问题

我在Dreamweaver中新建一个php文件saveaddleibie.php。代码如下：
<?php
include("conn/conn.php");
mysql_query("insert into tb_type(id,typename) values ('3','机械')",$conn);
?>
当然conn文件夹下的conn.php文件也写好。用DW打开saveaddleibie.php,按F12运行后，应该向数据库的tb_type表中插入数据。但结果令人无解，只插入成功'id'列的3,
'typename'列的'机械'没插入成功。具体看命令行的查询。如下图：

但我在命令行中输入语句insert into tb_type(id,typename) values ('3','机械')后，
两列都能正常插入。请各位大神，我该怎么办才能在用DW的方式正常插入两列数据呢？

汉字得编码在php中估计有问题。

个人觉得不至于一列成功一列不成功的情况
1、检查一下是不是后面有update操作，把另一个字段置空了
2、配置一下mysql日志，把执行的SQL记录下来，执行一次，查一下sql记录

我是提问者，根据回答者的提示，我配置了一下mysql日志，再在DW中按F12,执行一次插入，查看一下sql记录，还没找到原因。具体mysql日志如下：
