Data | Database This kind of personal thought is very useful!!! For the later submission of the form data, do not have to write a single one, directly referencing the class, then save or edit can be more simple, but of course, because it is not intelligent, so for some data format is not to do verification!! Use the sample code as follows:
<%
Dim Action
Action=request ("Action")
If action= "Save" Then
Dim Objclass
Set objclass=new Saveformdata
Objclass.mdbfile=server.mappath ("Data/data.mdb")
' Objclass.saverecord ' number, ' * ', ' ID '
Objclass.saverecord "Number", "Num1,text", ""
' Objclass.editrecord ' number ', ' * ', ' id=15 ', ' ID '
Set objclass=nothing
End If

Description of Class:
If you are using an Access database, you first specify the absolute address of the database! [OBJ]. mdbfile= "Database file Address"
If it is not an Access database, specify the Conn property of the Class object, example: Set [OBJ]. Conn=[connection Object]
You can then use
[OBJ]. Saverecord ("Table name", "Fill in the list of field names", "Do not fill in the list of field names") = Add new data
Note: This method returns TRUE or False,true new data is successful or fails!
Table name: Data table name to fill in the new record data
Fill Field Name list: field names when new data is added, separated by commas, such as: "Name,word,sex"
"Do not fill in field Name list": The fields included in this field list are not added when data is added.
[OBJ]. Saverecord "User", "*", "id"
[OBJ]. EditRecord (table name, modify field names list, modify criteria, do not modify field list) = Modify a piece of data
"Table name", "Modify Field List" and "Do not modify field list" are the same as the Saverecord Method!
"Modify condition": SQL query condition, without "WHERE"
Example: [OBJ]. EditRecord "User", "Pass,sex", "id=22", ""
Note: The Fill field List and modify field list can use the value or the "*" value, indicates that all fields are modified, but it is recommended that you write "Automatically add" field names in the "Do not fill in field Name list" and "Do not modify field names list", or you will fail to fill in or modify data!
