Theoretically, we want to use XQuery to connect spatial data.
Use GML to store space data.
Connect to GML using XQuery
The existing database platforms and 3 s platforms differ in the storage of spatial data in spatial databases.
However, all major relational databases support XML
You can consider using GML to represent spatial data in a relational database.
With this solution, the idea is very clear.

Target: XQuery-> spatial data.
Prerequisite 1: XQuery-> GML (implemented)
Prerequisite 2: XQuery-> relational data (available)
Solution:
Spatial Database = relational database + GML
XQuery-> spatial database = XQuery-> (Relational Data + GML) = XQuery-> Relational Data + xqury-> GML.
Relational data can be implemented in a common SQL statement and can be implemented using the LINQ interface.
