**APPLIES TO:** SQL Server (starting with 2008) Azure SQL Database Azure SQL Data Warehouse Parallel Data Warehouse

Returns a geometry instance from an Open Geospatial Consortium (OGC) Well-Known Text (WKT) representation with any Z (elevation) and M (measure) values carried by the instance.

Syntax

  
STMPolyFromText ( 'multipolygon_tagged_text' , SRID )  

Arguments

multipolygon_tagged_text
Is the WKT representation of the geometryMultiPolygon instance you wish to return. multipolygon_tagged_text is an nvarchar(max) expression.

SRID
Is an int expression representing the spatial reference ID (SRID) of the geometryMultiPolygon instance you wish to return.

Return Types

SQL Server return type: geometry

CLR return type: Sql Geometry

OGC type: MultiPolygon

Remarks

This method will throw a FormatException if the input is not well-formatted.

Examples

The following example uses STMPolyFromText() to create a geometry instance.

DECLARE @g geometry;  
SET @g = geometry::STMPolyFromText('MULTIPOLYGON (((5 5, 10 5, 10 10, 5 5)), ((10 10, 100 10, 200 200, 30 30, 10 10)))', 0);
