Hi General,

Is there a reason why it is not possible to redefine a view with a different number of columns or a different column type? It's been possible to change the datatypes of a table, and the column numbers for a long time. What are the restrictions on making this possible for views.

I know you can drop an recreate the view, but if the view has dependent objects it becomes more difficult.

That's why - the dependent objects might have to change with it.

I suppose it should be possible to add columns to a view without causing too many problems. Or change a column-definition provided it isn't referenced anywhere.
