PL/SQL

Question

Hi All,
Database Version: 11.2.0.3.0
We have requirement below:
From the java application one of our database procedure will be called, and one of the input parameter for the procedure is part_number and it can contain multiple values, so the java sends the part numbers with comma as the separator. we will be receiving all the values into a single variable.
Now i need loop through these part numbers one after the other, but as of now all the part number are in a single variable, How can i achieve this.
Example
l_part_num VARCHAR2(500):='9HH131-187','9HH131-188','9HH131-189';
Thanks and Regards
Srinivas

Use Collections to store the Comma Separated data.
set serveroutput on;
begin
  proc('abc,def,ghi,jkl');
end;
create or replace procedure proc(p_inp in varchar2)
is
  type typ is table of varchar2(10);
  vals typ;
begin
  select regexp_substr(p_inp, '[^,]+', 1, level)
    bulk collect into vals
    from dual
  connect by level <= length(p_inp) - length(replace(p_inp, ','));
  for i in 1..vals.count loop
    dbms_output.put_line('Val :: ' || vals(i));
  end loop;
end;
anonymous block completed
Val :: abc
Val :: def
Val :: ghiI will still recommend to correct the design by incorporating correct datatypes. See an example by Tom Kyte,
