發行項
12/15/2008

未來的 Microsoft SQL Server 發行版本將不再提供此功能。請避免在新的開發工作中使用此功能，並計劃修改目前使用此功能的應用程式。

The PhysicalDatatype property returns the name of the base data type for the referenced column.

語法

object
.PhysicalDatatype

Parts

object
An expression that evaluates to an object in the Applies To list

Data Type

String

Modifiable

Read-only

Prototype (C/C++)

HRESULT GetPhysicalDatatype(SQLDMO_LPBSTR pRetVal);

附註：
SQL Distributed Management Objects (SQL-DMO) strings are always returned as OLE BSTR objects. A C/C++ application obtains a reference to the string. The application must release the reference using SysFreeString.

備註

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.

Applies To:

Column Object
