Specifies that the function returns identical results for identical inputs.

DETERMINISTIC and NOT DETERMINISTIC are optional and can only be specified once per function definition.

NOT
Specifies that the function does not always return identical results for identical inputs.

For example, if the function calls a random number generator as part of its processing, then the results of a function call cannot be known in advance of making the call and the function is NOT DETERMINISTIC.

The default is NOT DETERMINISTIC.
