Regular expression to extract numbers

Yellow75May 23 2016 — edited May 23 2016

Hi,

I'm trying to extract from a string only numbers that are in round brackets:

SELECT


 REGEXP_REPLACE ( 'FGF(23) SAD8WED(35) (EDRF(FG9', '[^([:digit:])]', '-') AS REG


FROM DUAL;

Output:

---(23)----8---(35)-(----(--9

but i want to achieve this result:

----23----------35-----------

Thanks,

Igor
