Parse (geography data type)
Applies to: 
SQL Server
Azure SQL Database
Azure SQL Managed Instance
SQL database in Microsoft Fabric
Returns a geography instance from an Open Geospatial Consortium (OGC) Well-Known Text (WKT) representation. Parse() is equivalent to STGeomFromText (geography Data Type), except that it assumes a spatial reference ID (SRID) of 4326 as a parameter. The input might 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
The WKT representation of the geography instance to return. geography_tagged_text is nvarchar(max).
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' is interpreted as a null geography instance.
This method throws ArgumentException if the input contains an antipodal edge.
Examples
The following example uses Parse() to create a geography instance.
DECLARE @g geography;
-- Starting point: Lat. 47.656, Lon. -122.360
-- Ending point: Lat. 47.656, Lon. -122.343
SET @g = geography::Parse('LINESTRING(-122.360 47.656, -122.343 47.656)');
SELECT @g.ToString();
