BaseType Property
This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
The BaseType property exposes the system data type from which a user-defined data type has been derived.
Syntax
object
.BaseType [= value]
Parts
- object
An expression that evaluates to an object in the Applies To list
- value
A text string that identifies a Microsoft SQL Server system data type
Data Type
String
Modifiable
Read/write
Prototype (C/C++)
HRESULT GetBaseType(SQLDMO_LPBSTR pRetVal);
HRESULT SetBaseType(SQLDMO_LPCSTR NewValue);
Note
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 by using SysFreeString.
Remarks
The BaseType property is only modifiable before the UserDefinedDatatype object has been added to the UserDefinedDatatypes collection of a Database object. After the object is added to the collection and the user-defined data type is created on an instance of SQL Server, the property is read-only.
