Objective:
To split the given string separated by special character as an individual column value using oracle pipelined Function.
Step 1:
Create table type of varchar:
create or replace type split_tbl as table of varchar2(32767);
Step 2:
Create a Pipelined function as below:
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;
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;
Step 3:
Get the Comma separated value as separate row value as below.
SELECT COLUMN_VALUE my_string FROM TABLE (split(‘Aishwarya,Aish,A’));
Output:
