Parse (geography Data Type)
Returns a geography instance from an Open Geospatial Consortium (OGC) Well-Known Text (WKT) representation. Parse() is equivalent to STGeomFromText, except that it assumes a spatial reference ID (SRID) of 4326 as a parameter. The input may carry optional Z (elevation) and M (measure) values.
This geography data type method supports FullGlobe instances or spatial instances that are larger than a hemisphere.
Syntax
Parse ( 'geography_tagged_text' )
Arguments
- geography_tagged_text
Is the WKT representation of the geography instance to return. geography_tagged_text is an nvarchar expression.
Return Types
SQL Server return type: geography
CLR return type: SqlGeography
Remarks
The OGC type of the geography instance returned by Parse() is set to the corresponding WKT input.
The string 'Null' will be interpreted as a null geography instance.
This method will throw ArgumentException if the input contains an antipodal edge.
Examples
The following example uses Parse() to create a geography instance.
DECLARE @g geography;
SET @g = geography::Parse('LINESTRING(-122.360 47.656, -122.343 47.656)');
SELECT @g.ToString();
