I want to select split records from the phone column.
My table looks like that:
customerId      phone                       address      ...
 1              1234567                     qwe          ...
 2              234567,135791,4556457       asd          ...
 3              3425546,34454365            zxc          ...
I need to select each phone number separately with the customerId:
1  1234567
2  234567
2  135791
2  4556457
3  3425546
3  34454365
I don't want to change table and split to different rows, only to select.
Thanks!
