附：各字段对应的变量的数据类型
Private mvarG_ID As String
Private mvarG_Name As String
Private mvarG_Linkman As String
Private mvarG_Duty As String
Private mvarG_OfficePhone As String
Private mvarG_MobilePhone As String

Private mvarG_Cooperate As String
Private mvarG_Demand As String
Private mvarG_Maintenance As Date
Private mvarG_Actualize As String
Private mvarG_Feedback As String
Private mvarG_Settle As String
Private mvarG_Importance As Integer
Private mvarG_Friendly As Integer
Private mvarG_Satisfaction As Integer
Private mvarG_Remark As String


添加操作完全正常，修改操作总提示"Update语法错误"！

下面是Debug.Print strSQL
update GuestInfo set (G_Name='wewe',G_Linkman='wewe',G_Duty='wewe',G_OfficePhone='123',G_MobilePhone='123',G_Fax='123',G_Address='123',G_Cooperate='123',G_Demand='123',G_Maintenance=2007-2-5,G_Actualize='是',G_Feedback='123',G_Settle='否',G_Importance='2',G_Friendly='2',G_Satisfaction='2',G_Remark='2' where G_ID='GNO.007')

我被忽悠晕，大家帮我看看吧，数据库的操作代码我就不贴了！
