Parse (geography Data Type)
Applies To: SQL Server 2014, SQL Server 2016 Preview
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.
Applies to: SQL Server (SQL Server 2008 through current version), Azure SQL Database.
Is the WKT representation of the geography instance to return. geography_tagged_text is an nvarchar expression.
SQL Server return type: geography
CLR return type: SqlGeography
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.
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();
