STGeomFromText (geography Data Type)
Returns a geography instance from an Open Geospatial Consortium (OGC)Well-Known Text (WKT) representation augmented with any Z (elevation) and M (measure) values carried by the instance.
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.|
STGeomFromText ( 'geography_tagged_text' , SRID )
Is the WKT representation of the geography instance to return. geography_tagged_text is an nvarchar(max) expression.
Is an int expression representing the spatial reference ID (SRID) of the geography instance to return.
SQL Server return type: geography
CLR return type: SqlGeography
The OGC type of the geography instance returned by STGeomFromText() is set to the corresponding WKT input.
This method will throw an ArgumentException if the input contains an antipodal edge.
The following example uses
STGeomFromText() to create a
DECLARE @g geography; SET @g = geography::STGeomFromText('LINESTRING(-122.360 47.656, -122.343 47.656)', 4326); SELECT @g.ToString();
