Beside this, what is deterministic SQL?

Overview. SQL functions in SQLite can be either " deterministic " or "non- deterministic ". A deterministic function always gives the same answer when it has the same inputs. For example, the abs(X) function always returns the same answer as long as its input X is the same.

Additionally, what is deterministic and nondeterministic function in SQL Server? Functions can be either deterministic or nondeterministic . A deterministic function always returns the same results if given the same input values. A nondeterministic function may return different results every time it is called, even when the same input values are provided.

Besides, what is a deterministic statement?

DETERMINISTIC Functions. The DETERMINISTIC clause for functions is ideal for functions that do not have any non- deterministic components. This means that each time you provide the function with the same parameter values, the result is the same. Function-based indexes can only use functions marked DETERMINISTIC .

What is the difference between deterministic and nondeterministic?

In deterministic algorithm, for a given particular input, the computer will always produce the same output going through the same states but in case of non-deterministic algorithm, for the same input, the compiler may produce different output in different runs.
