Question

Lets say I have a table that has a bit column named Active. By default, the column will contain a value of false for every row except one. When I choose to use a gridview to update a new row and have its ‘Active’ column change from false to true…

How can I modify the following update command to update all previous rows to false when a new row is to be set to true. ( I only want to have one row be set to active(true) at a time in this table).

UpdateCommand="UPDATE [RbSpecials] 
                  SET [Name] = @Name, 
                      [Description] = @Description, 
                      [Active] = @Active 
                WHERE [ID] = @ID">

UPDATE [RbSpecials] 
SET 
    [Name] = @Name, 
    [Description] = @Description, 
    [Active] = @Active WHERE [ID] = @ID

UPDATE [RbSpecials] 
SET 
    [Active] = 0 WHERE [ID] != @ID

You could create a stored procedure that does this and then just pass @Name, @Description and @ID.
