Does Tangram support updates?

I have a few questions regarding the Tangram ORM.

Can some Tangram guru advise what does it mean that 开发者_C百科Tangram has no support for SQL UPDATE? Also, is this ORM in general a good choice and in what cases?

Well, it does support SQL UPDATE. Solving another problem (partial column select -- I hardly understand what it means) might result in such inability. That's how I've read the doc you linked to.

My experience with Tangram is very limited, though.
