oracle - Split string into tokens in pl sql -


how can parse string tokens in pl/sql?

for example, string:

170823-14785

and parsing want is:

17 08 23 -1 47 85

as see, want replace consecutive 2 chars, following space symbol

if so, this: (no pl/sql needed this)

select regexp_replace('170823-14785', '(.{2})', '\1 ') dual;
