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.
STLineFromText ( 'linestring_tagged_text' , SRID )
linestring_tagged_text
Is the WKT representation of the geometryLineString instance you wish 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 wish to return.
SQL Server return type: geometry
CLR return type: SqlGeometry
OGC type: LineString
This method will throw a FormatException if the input is not well-formatted.
The following example uses STLineFromText()
to create a geometry
instance.
DECLARE @g geometry;
SET @g = geometry::STLineFromText('LINESTRING (100 100, 200 200)', 0);
SELECT @g.ToString();
