[!INCLUDE SQL Server Azure SQL Database Azure SQL Managed Instance FabricSQLDB]
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.
STGeomFromWKB ( 'WKB_geography' , SRID )
WKB_geography
Is the WKB representation of the geography instance to return. WKB_geography is a varbinary(max) expression.
SRID
Is an int expression representing the spatial reference ID (SRID) of the geography instance to return.
[!INCLUDEssNoVersion] 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 geography instance.
DECLARE @g geography;
SET @g = geography::STGeomFromWKB(0x010200000002000000D7A3703D0A975EC08716D9CEF7D34740CBA145B6F3955EC08716D9CEF7D34740, 4326);
SELECT @g.ToString();
