STGeomFromText (geometry Data Type)

 

THIS TOPIC APPLIES TO:yesSQL Server (starting with 2008)yesAzure SQL DatabasenoAzure SQL Data Warehouse noParallel Data Warehouse

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.

Applies to: SQL Server (SQL Server 2008 through current version), Azure SQL Database.
  
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();
