03:45 27 Jan 2022 
id   item_name  cust_id 
1     Rolex      5        
2     Diamond    33 
3     Hublop     1         
4     Ring       9          
5     Ruby       13 
6     Rolex      33 
7     Hublop     29 
8     Ring       17 
9     Belt       21 
10    Diamond     9       
12    Belt       33
13    Hublop      9                                                                                                                                                           
14    Brooch      9

From these table I have to write a query to find those cust_id who have buy all three 'diamond,brooch,ring' without using intersection ( IN clause will also not work)
