Returns a geometry instance from an Open Geospatial Consortium (OGC) Well-Known Text (WKT) representation augmented with any Z (elevation) and M (measure) values carried by the instance.
STGeomFromText ( 'geometry_tagged_text' , SRID )
-
geometry_tagged_text
-
Is the WKT representation of the geometry instance you wish to return. geometry_tagged_text is an nvarchar(max) expression.
-
SRID
-
Is an int expression representing the spatial reference ID (SRID) of the geometry instance you wish to return.
SQL Server return type: geometry
CLR return type: SqlGeometry
The OGC type of the geometry instance returned by STGeomFromText() is set to the corresponding WKT input.
This method will throw a FormatException if the input is not well-formatted.
The following example uses STGeomeFromText() to create a geometry instance.
DECLARE @g geometry;
SET @g = geometry::STGeomFromText('LINESTRING (100 100, 20 180, 180 180)', 0);
SELECT @g.ToString();
