STMPolyFromText ( 'multipolygon_tagged_text' , SRID )
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.
[!INCLUDEssNoVersion] return type: geometry

This method will throw a FormatException if the input is not well-formatted.
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);
SELECT @g.ToString();
