STGeomCollFromText ( 'geometrycollection_tagged_text' , SRID )

geometrycollection_tagged_text

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

SRID

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

The OGC type of the geography instance returned by STGeomCollFromText() is set to the corresponding WKT input.

This method throws an ArgumentException if the input is not valid.

The following example uses STGeomCollFromText() to create a geography instance.

DECLARE @g geography;
DECLARE @g geography;
SET @g = geography::STGeomCollFromText('GEOMETRYCOLLECTION ( POINT(-122.34900 47.65100), LINESTRING(-122.360 47.656, -122.343 47.656) )', 4326);
