Description

I have a vertex that has embeddedlist columns that reference records in other vertices with the @rids. If I do a simple select, I can see the @rids for this embedded column and if I click on it and I can see the referenced record. How do I select the embedded values in an SQL? I tried expand() on the column and the only thing I see if still the @rid.

Kindly see an example below. How do I display a contact and all embedded phones in one query?

Contact

Name ---- STRING
Description ---- STRING
Phone ---- EMBEDDEDLIST ----> @rid of corresponding record in Phone vertex displayed

Phone

Home Phone ---- STRING
Office Phone. ---- STRING
