Oracle SQL randomising column entries

I have the below table:

PC	A	MAXI
PC1	A1	1
PC1	A2	2
PC1	A3	3
PC2	A1	1
PC2	A2	2
PC2	A3	3

Is there a way to generate ‘MAXI’ entries for each group of ‘PC’ and ‘A’ in a random order (or at least a seemingly even distribution, even if not random)?

Desired output (count_pc would just be an order count over partition by PC):

PC	A	COUNT_PC
PC1	A2	1
PC1	A1	2
PC1	A3	3
PC1	A3	4
PC1	A2	5
PC1	A3	6
PC2	A3	1
PC2	A2	2
PC2	A3	3
PC2	A1	4
PC2	A2	5
PC2	A3	6

Answer

You can generate your rows using your favorite method, then use a random number generator for the last column (with row_number()):

with cte(pc, a, maxi) as (
      select pc, a, maxi
      from t
      union all
      select pc, a, maxi - 1
      from cte
      where maxi > 1
     )
select pc, a,
       row_number() over (partition by pc order by dbms_random.random) as count_pc
from cte
order by pc, count_pc;
