Valid Geometry Formats

UPDATE: Close - Answered my own question. I'll leave this up here for others. But basically, just don't create the geometry in the database. When I bring over the concatenated string as a multipoint character field, YF's convert feature appears and it let me conver to WKT.

--Hopefully this will help some others!

Hey there, I was reading a post from a few years ago where the customer was having an issue with YF interpreting multipoints/polygons. I'm able to create point geometries just fine. I was wondering if there's a guide anywhere or general guidelines for allowable geometries. I've created a multipoint geometry field that displays just fine in SQL Server Management Studio's spatial results.

When I use this data in a view in YF, the field comes across with just the binary data. In the report, it gives a hyperlink to "download" and the convert function is not available.

I've gone through the Wiki as well as YF University and am not seeing anything beyond the basic x/y point concatenation. Note that in SQL, I need to use y/x to form the geometry as the STGeomFromText method requires longitude first.

Here are some screenshots:

sample code that works in SQL

 select geometry::STGeomFromText('MULTIPOINT('+
		string_agg(convert(varchar(max), 
		concat(fromlon,' ',fromlat)+', '+concat(tolon,' ',tolat)
		)
		,', ') 
		within group (order by segmentid, shapeid)+')',0)
 from poly

Please point me to any documentation you might have on utilizing geometry/geography columns other than POINT.

Thanks!
