      Description

      Oracle has a regularly used function called NVL(expr1,expr2). It appears to be the same as mariadb expression IFNULL(expr1,expr2). This request is to create a NVL function for Oracle compatibility.

      ______

      Syntax
      The syntax for the NVL function in Oracle/PLSQL is:

      NVL( string1, replace_with )
      Parameters or Arguments
      string1
      The string to test for a null value.
      replace_with
      The value returned if string1 is null.
      Returns
      The NVL function returns a substitute value.

      This task also included function NVL2(expr1,expr2,expr3)
      If expr1 is TRUE .. then it returns exp2, otherwise returns expr3
