SYMPTOMS

When attempting to perform a table update, the following message appears:

Query Based Insertion or Updating of BLOB values can not be supported. This may be caused by an attempt to update a non-primary table in a view

CAUSE

ActiveX Data Objects (ADO) 1.0 does not support updating long text fields with a forward-only cursor.

RESOLUTION

Use a cursor that supports bookmarks (for example, Keyset or Static).

STATUS

This behavior is by design.

MORE INFORMATION

If you have used Visual InterDev's DataForm Wizard to create the code that is experiencing this problem, follow these instructions:

Edit xxxForm.asp.
Search for the text: "DesignerControl" startspan.
Right-click any of the text that is displayed in green, and select "Edit Design-time Control..."
Click the Advanced tab.
Change the "Cursor Type" to one that supports bookmarks (for example, 3- Static).
Save the changes.
Edit xxxList.asp and perform steps 2-6 again.
