IsDeterministic Property

Esta característica se quitará en una versión futura de Microsoft SQL Server. Evite utilizar esta característica en nuevos trabajos de desarrollo y tenga previsto modificar las aplicaciones que actualmente la utilizan.

The IsDeterministic property specifies whether a user-defined function is a deterministic function.

HRESULT GetIsDeterministic(LPBOOL pRetVal);

Notas

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 whether 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.

[!NOTA] 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 or later" are returned.
