oracle - How to remove unique characters from a string in SQL -


what function can use rid of characters within string? know can use replace() function there around 30 variables need doing hoping more efficient route.

example:

what shows: 

basicpay_5000 carallowance_6000 bonus_7000

what need show: 

5000 6000 7000

is there function removes characters pre-defined character? e.g. writing statement removes characters _ (underscore).

this should help

select substr('basicpay_5000', instr('basicpay_5000','_') + 1) dual

basicpay_5000 can replaced data have, if in said format
