Create a polygon via SQL

Question

I have an existing spatial/polygon table in my database. I want to join it to a view and load the join into a new spatial enabled polygon table. In case you are wondering the join is very slow. I am new to SQL Server spatial and cant find anything describing
how to do this. Ultimately I will use SSIS to perform these steps for me. I have been able to do this with point data but not polygon. The existing polygon coordinates are in a Shape field and will load into another field of the same name. Here is the query
I have built so far:
select name, geography::Polygon(Shape, 4326) as Shape
FROM View as c inner join ExistingPolygonTable as v
on C.Name = v.Name
Thanks in advance.

There is no Polygon static method like there is with Point. You can create a polygon from WKT (well-known text format) using these methods:

just to store it, just store it with the TSQL insert...select statement

Or maybe I've misunderstood the question, or don't know what's in the ExistingPolygonTable. Or what format it's in in that table.
