Multiple values as Input Parameter

Question

Hi All,
I need some help on how to implement
Create or replace Pr( p_id in varchar2)
is
begin
select empname from emp where empid = p_id;
end;
The above will work fine if i pass one value how to handle if i want to pass multiple id's (comma seperated or tab ).
I tried it with dbms_utility.COMMA_TO_TABLE the output is not consistant.
Can some one please give inputs
Thanks

You can give input parameter as a String, then just split by coma seperator or something else...
You can use the following split function in your procedure..
FUNCTION SPLIT (p_in_string VARCHAR2, p_delim VARCHAR2) RETURN t_array 
   IS
      i       number :=0;
      pos     number :=0;
      lv_str  varchar2(50) := p_in_string;
   strings t_array;
   BEGIN
      -- determine first chuck of string  
      pos := instr(lv_str,p_delim,1,1);
      -- while there are chunks left, loop 
      WHILE ( pos != 0) LOOP
         -- increment counter 
         i := i + 1;
         -- create array element for chuck of string 
         strings(i) := substr(lv_str,1,pos);
         -- remove chunk from string 
         lv_str := substr(lv_str,pos+1,length(lv_str));
         -- determine next chunk 
         pos := instr(lv_str,p_delim,1,1);
         -- no last chunk, add to array 
         IF pos = 0 THEN
            strings(i+1) := lv_str;
         END IF;
      END LOOP;
      -- return array 
      RETURN strings;
   END SPLIT; After spliting you will got an array of values... Just use them in loop or wherever you want
