STLineFromText (geometry)#
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.
Syntax#
.STLineFromText ( 'linestring_tagged_text' , SRID )
Arguments#
linestring_tagged_text
Is the WKT representation of the geometryLineString instance you want to return. linestring_tagged_text is an nvarchar(max) expression.
SRID
Is an int expression representing the spatial reference ID (SRID) of the geometryLineString instance you want to return.
Return type#
geometry
Remarks#
This method throws a FormatException if the input isn’t well-formatted. Three-dimension and measured geometry WKT notation from the Open Geospatial Consortium (OGC) Simple Features for SQL Specification version 1.2.1 aren’t supported. See examples for the supported representation of Z (elevation) and M (measure) values.
Example#
Use STLineFromText() to create a geometry instance from a two-dimension geometry WKT.
DECLARE @g geometry;
SET @g = geometry::STLineFromText('LINESTRING (100 100, 200 200)', 0);
SELECT @g.ToString();
