Remarks

The ST_Y function returns the Y coordinate (latitude or northing) of a point geometry. For non-point geometries, the result is typically null or undefined. The Y coordinate represents the vertical position in the coordinate reference system. For geographic coordinates, Y is latitude. For projected coordinates, Y is the northing value. For Geometry types in planar coordinate systems, this is useful for extracting coordinates, coordinate transformations, or point analysis. OGC-compliant.

Constructors
