I’m trying to design a report in VS2005 BIDS Report Designer, but every so often, I haven’t figured out any regular action that might cause it, but when I try and run the query, I get the following error:
An error occurred while retrieving the
parameters in the query.
DeriveParameters requires an open and
available Connection. The connection’s
current state is closed
What causes this and what can I do to open the connection again?
Having searched the interwbes for this same problem, the answer validated on my part, is to close and reopen the Visual Studio solution.
