Generating Random Number In Each Row In Oracle Query

Question

I want to select all rows of a table followed by a random number between 1 to 9:

select t.*, (select dbms_random.value(1,9) num from dual) as RandomNumber
fr         


        

Answer 1

you don’t need a select … from dual, just write:

SELECT t.*, dbms_random.value(1,9) RandomNumber
  FROM myTable t
