ST_MakePoint

ST_MakePoint takes two numeric columns and returns a point column. The two input columns must contain the x,y coordinates of the points respectively. You can optionally specify two additional input columns with z-coordinates and m-values. The spatial reference of the result column will always be 0 and should be set to a valid ID using ST_SRID.

For more details, go to the GeoAnalytics for Microsoft Fabric API reference for make_point.

This function implements the OpenGIS Simple Features Implementation Specification for SQL 1.2.1.
