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.


Setting Properties


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.
