Syntax

'Declaration
Public ReadOnly Property IsDeterministic As Boolean

public bool IsDeterministic { get; }

/** @property */
public boolean get_IsDeterministic ()

public function get IsDeterministic () : boolean

Property Value

A Boolean value that specifies the whether the user-defined function is deterministic or not. If True, the user-defined function is deterministic. If False (default), the user-defined function is not deterministic.

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 this property to determine if a computed column that depends on a user-defined function can be used in an index.

This namespace, class, or member is supported only in version 2.0 of the Microsoft .NET Framework.
