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

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();
