Warning

Spatial functions are not available in the Community Edition of Velocity. They require the Full Edition.

The ST_GeometryType function returns the OGC geometry type name as a string, such as "POINT", "LINESTRING", "POLYGON", "MULTIPOINT", "MULTILINESTRING", "MULTIPOLYGON", or "GEOMETRYCOLLECTION". The returned value typically includes the "ST_" prefix (e.g., "ST_Point"). For Geometry types in planar coordinate systems, this is useful for filtering by geometry type, validation, or determining appropriate spatial operations based on type. OGC-compliant.

Return Type: String (geometry type name).

Geometry	Returned String
Point	"Point" or "ST_Point"
LineString	"LineString" or "ST_LineString"
Polygon	"Polygon" or "ST_Polygon"
MultiPoint	"MultiPoint" or "ST_MultiPoint"
MultiLineString	"MultiLineString" or "ST_MultiLineString"
MultiPolygon	"MultiPolygon" or "ST_MultiPolygon"
GeometryCollection	"GeometryCollection" or "ST_GeometryCollection"
