Interaction RecursionSo far, we have seen recursive functions that call ourselves directly. Although most recursive functions comply with this form, recursion is more widely defined. If a function is subdivided into several subfunctions, you can apply recursive calls at a deeper nesting level. For example, if function f calls function g and function g calls function f in turn, these functions are still called as recursion. This type of recursion becomes interactive Recursion

In some scenarios we may need to generate some random data, such as generating phone numbers, e-mail addresses and other data in a test environment for functional testing. Or import the production data into the test environment for simple desensitization processing. This is what I developed on the basis of dbms_random to generate:
