It is more then just a headers issue. I have a view that has a column of type numeric(20,4).

I modified the view and added a union which cast an integer as a numeric(20,4) using the :: notation.

I received an error stating that I could not change the column type.

When I used the cast function notation it allowed it through.

The fact that it actually converts it to numeric(20,4) doesn't help me if the view thinks that it is a regular numeric.

Really?  Your example doesn't seem to show that.
    

I think he's talking about the headers
