Retrieving the record to update (ASP and JSP)

Retrieving the record to update (ASP and JSP)

After the results page passes a URL parameter to the update page identifying the record to update (see Opening the update page and passing the record ID (ASP and JSP)), the update page must read the parameter, retrieve the record from the database table, and store it temporarily in a recordset.

To retrieve the record to update:

  1. Create a new ASP or JSP page in Dreamweaver and save it.

    The page will become your update page.

  2. In the Bindings panel (Window > Bindings), click the Plus (+) button and select Recordset.

    If the advanced dialog box appears, click the Simple button to open the simple dialog box.

  3. Name the recordset and specify where the data you want to update is located using the Connection and Table pop-up menus.
  4. Click the Selected option and select a key column (usually the record ID column) and the columns containing the data to be updated.
  5. Configure the Filter area so that the value of your key column equals the value of the corresponding URL parameter passed by the results page.

    This kind of filter creates a recordset that contains only the record specified by the results page. For example, if your key column contains record ID information and is called PRID, and if the results page passes the corresponding record ID information in the URL parameter called id, then here’s how your Filter area should look:

    This is a picture of the feature being described.

  6. Click OK.

When the user selects a record on the results page, the update page will generate a recordset containing only the selected record.

After modifying the update page to retrieve a record from the database and store it in a recordset, you must add a form to let users modify the record data, and the logic needed to update the database. You can accomplish these tasks in one operation or block by block. See Completing the update page in one operation (ASP and JSP) or Completing the update page block by block (ASP and JSP).
