STGeomCollFromText (geometry Data Type)
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.
Syntax
STGeomCollFromText ( 'geometrycollection_tagged_text' , SRID )
Arguments
geometrycollection_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.
Return Types
SQL Server return type: geometry
CLR return type: SqlGeometry
Remarks
The OGC type of the geometry instance returned by STGeomCollFromText() is set to the corresponding WKT input.
This method will throw an exception if the input is not valid.
Examples
The following example uses STGeomCollFromText() to create a geometry instance.
DECLARE @g geometry;
SET @g = geometry::STGeomCollFromText('GEOMETRYCOLLECTION ( POLYGON((5 5, 10 5, 10 10, 5 5)), POINT(10 10) )', 0);
SELECT @g.ToString();
