Hinweise
For a Microsoft SQL Server column created using a base data type, the referencing Column object Datatype and PhysicalDatatype properties have identical values. For a SQL Server column created using a user-defined data type, the referencing Column object Datatype property returns the name of the user-defined data type. The PhysicalDatatype property reports the SQL Server base data type.
