 # SQL API Reference
 
-The following SQL functions are available for SedonaDB.
-
-You can query data directly from files and URLs by treating them like database tables. This feature supports formats like **Parquet**, **CSV**, and **JSON**.
-
-To query a file, place its path or URL in single quotes within the `FROM` clause.
-
-```python
-# Query a remote Parquet file directly
-"SELECT * FROM 'https://raw.githubusercontent.com/geoarrow/geoarrow-data/v0.2.0/natural-earth/files/natural-earth_cities_geo.parquet'").show()

-Aggregates a set of geometries into a single `GeometryCollection`, `MultiPoint`, `MultiLineString`, or `MultiPolygon`. If all input geometries are of the same type (e.g., all points), it creates a multi-geometry of that type. If the geometries are of mixed types, it returns a `GeometryCollection`.
+Returns the 2-dimensional point on geom1 that is closest to geom2. This is the first point of the shortest line between the geometries. If using 3D geometries, the Z coordinates will be ignored. If you have a 3D Geometry, you may prefer to use ST_3DClosestPoint. It will throw an exception indicates illegal argument if one of the params is an empty geometry.
