Parse (geography Data Type)
Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance
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' )
Note
To view Transact-SQL syntax for SQL Server 2014 (12.x) and earlier versions, see Previous versions documentation.
Arguments

Is the WKT representation of the geography instance to return. geography_tagged_text is an nvarchar expression.
Return Types

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.

SET @g = geography::Parse('LINESTRING(-122.360 47.656, -122.343 47.656)');
SELECT @g.ToString();
