Convert comma separated string to array in PL/SQL

Question

How do I convert a comma separated string to a array?

I have the input \'1,2,3\' , and I need to convert it into an array.

Answer 1

A quick search on my BBDD took me to a function called split:

create or replace function split
( 
p_list varchar2, 
p_del varchar2 := ','
) 
return split_tbl pipelined
is 
l_idx pls_integer; 
l_list varchar2(32767) := p_list;AA 
l_value varchar2(32767);
begin 
loop 
l_idx := instr(l_list,p_del); 
if l_idx > 0 then 
pipe row(substr(l_list,1,l_idx-1)); 
l_list := substr(l_list,l_idx+length(p_del));
else 
pipe row(l_list); 
exit; 
end if; 
end loop; 
return;
end split;

I don't know if it'll be of use, but we found it here...
