Is the WKT representation of the geography instance you wish to return. geometrycollection_tagged_text is an nvarchar(max) expression.
- srid
Tipo: System.Int32
Is an int expression representing the spatial reference ID (SRID) of the geography instance you wish to return.
Valore restituito
Tipo: Microsoft.SqlServer.Types.SqlGeography
A geography instance.
Osservazioni
The OGC type of the geography instance returned by STGeomCollFromText is set to the corresponding WKT input.
This method throws an ArgumentException if the input is not valid.
