属性值

类型：System. . :: . .Boolean
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.

注释

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.
