是否有可能获得dbms_random.random的源代码？

Question

是否可以获取dbms_random.random的源代码？或至少知道它是如何完成的？

例如，一种方法是

  randomValue = RandSeed * $08088405 + 1
  RandSeed = randomValue 

但是dbms_random.value是怎么做的？

Answer 1

是；搜索dbmsrand.sql。在我的Oracle 11g XE上，它位于

C:\oraclexe\app\oracle\product\11.2.0\server\rdbms\admin\dbmsrand.sql

Answer 2

plsql源在Oracle数据库中可用。

    --  OVERVIEW
    --
    --  This package should be installed as SYS.  It generates a sequence of
    --  random 38-digit Oracle numbers.  The expected length of the sequence
    --  is about power(10,28), which is hopefully long enough.
    --
    --------
    --  USAGE
    --
    --  This is a random number generator.  Do not use for cryptography.
    --  For more options the cryptographic toolkit should be used.
    --
    --  By default, the package is initialized with the current user
    --  name, current time down to the second, and the current session.
    --
    --  If this package is seeded twice with the same seed, then accessed
    --  in the same way, it will produce the same results in both cases.
