- <%' Defining some constants to make my life easier! (Same as Sample 1 & 2)
- ' Begin Constant Definition
-
- ' DB Configuration constants
- ' Fake const so we can use the MapPath to make it relative.
- ' After this, strictly used as if it were a Const.
- Dim DB_CONNECTIONSTRING
-
- ' ODBC
- 'DB_CONNECTIONSTRING = "DRIVER={Microsoft Access Driver (*.mdb)};" _
- ' & "DBQ=" & Server.Mappath("./db_scratch.mdb") & ";"
-
- ' OLE DB
- DB_CONNECTIONSTRING = "Provider=Microsoft.Jet.OLEDB.4.0;" _
- & "Data Source=" & Server.Mappath("db_dsn.mdb") & ";"
-
- ' We don't use these, but we could if we neeeded to.
- 'Const DB_USERNAME = "username"
- 'Const DB_PASSWORD = "password"
-
- 'Now we override the above settings to use our SQL server.
- 'Delete the following line to use the sample Access DB.
- DB_CONNECTIONSTRING = Application("SQLConnString")
-
- ' ADODB Constants
- ' You can find these in the adovbs.inc file
- ' Do a search for it and it should turn up somewhere on the server
- ' If you can't find it you can download our copy from here:
- ' http://www.asp101.com/samples/download/adovbs.inc
- ' It may not be the most recent copy so use it at your own risk.

- ' 1. Create a Recordset object
- ' 2. Connect the Recordset to the table
- ' 3. Find the record to update

- ' one so we don't cause SQL query errors. I use 0 since I

- ' recordset.Open Source, ActiveConnection, CursorType, LockType, Options
- objRecordset.Open strSQL, DB_CONNECTIONSTRING, adOpenKeyset, adLockPessimistic, adCmdText
-
- 'Step 3:
- ' The recordset should only have the one record so:
- If Not objRecordset.EOF Then
- objRecordset.MoveFirst
-
- 'Step 4:
- 'Only update if we've got a record, o/w we never run this
-
- ' String / Text Data Type

- ' Integer Data Type

- 'Only update if we've got a record, o/w we never run this
- objRecordset.Update
-
- Response.Write "Record id " & iRecordToUpdate & " updated!"
- End If
-
- 'Step 6:
- ' Finally we close the recordset and release the memory used by the
- ' object variable by setting it to Nothing (a VBScript keyword)
- objRecordset.Close
