STGeomFromWKB (geography Data Type)
Returns a geography instance from an Open Geospatial Consortium (OGC) Well-Known Binary (WKB) representation.
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.|
STGeomFromWKB ( 'WKB_geography' , SRID )
Is the WKB representation of the geography instance to return. WKB_geography is a varbinary(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 WKB input.
This method throws a FormatException if the input is not well-formatted.
This method will throw ArgumentException if the input contains an antipodal edge.
The following example uses
STGeomFromWKB() to create a
DECLARE @g geography; SET @g = geography::STGeomFromWKB(0x010200000002000000D7A3703D0A975EC08716D9CEF7D34740CBA145B6F3955EC08716D9CEF7D34740, 4326); SELECT @g.ToString();
