HRESULT GetIsDeterministic(LPBOOL pRetVal);
Remarks
A computed column can be used as a key column in an index or as part of any PRIMARY KEY or UNIQUE constraint, if the computed column value is defined by a deterministic expression and the data type of the result is allowed in indexed columns.
An application can use the IsDeterministic property to determine if a computed column that depends on a user-defined function can be used in an index.
IsDeterministic returns TRUE if a user-defined function is deterministic.
Note If an application calls IsDeterministic on an instance of Microsoft® SQL Server™ version 7.0, the constant, SQLDMO_E_SQL80ONLY, and the message "This property or method requires Microsoft SQL Server 2000" are returned.
