Datatype Property
The Datatype property exposes the data type name for the referenced column.
Applies To
| Column Object |
Syntax
object.Datatype [= value]
Parts
object
Expression that evaluates to an object in the Applies To list
value
Text string that identifies a Microsoft® SQL Server™ system or user-defined data type
Data Type
String
Modifiable
Read/write before column creation. Read-only when referencing an existing column.
Prototype (C/C++)
HRESULT GetDatatype(SQLDMO_LPBSTR pRetVal);
HRESULT SetDatatype(SQLDMO_LPCSTR NewValue);
Note 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.
Remarks
The Datatype property may not completely define the data type of a column. Columns requiring width specification, such as varchar, or specification of scale and precision, such as decimal, are defined using the Datatype property in concert with Length, NumericPrecision, and NumericScale properties.
Use the AlterDataType method to change the data type of an existing column.
