select orig,
regexp_replace(orig,’[0-9]‘,”,1
regexp_replace(orig,’[a-zA-Z]‘,’
from (select ‘helloe12te3st’ orig from dual);

ORIG
————-
REGEXP_REPLACE(ORIG,’[0-9]‘,”,1,0,’NM’)
——————————————–
REGEXP_REPLACE(ORIG,’[A-ZA-Z]‘,”,1,0,’NM’)

select replace(translate(data,
replace(translate(data,’0123456789′,’0000000000′),’0′,null),rpad(’z',length(data),’z')),’z',null)
from
(select ‘hello5623′ data from dual)

to extract the numeric data

Best regards,
