sql - Return cursor results from anonymous block -

i have following select want change anonymous block (need use anonymous block doing within java , not have access created stored functionality) in order remove use of literal bind variable:

select il.lat_num, il.lngtd_num item_location il il.item_id = 294341; 

i have 2 anonymous blocks created unable find how return values created in both:

1)

declare     itemid number;     latitude number;     longitude number; begin     itemid := 294341;      select          il.lat_num,         il.lngtd_num,             latitude,         longitude,              item_location il              il.item_id = itemid ;    end; 

2)

declare     type t_ref_cursor ref cursor;     c_cursor  t_ref_cursor;     itemid number;     latitude   item_location.lat_num%type;     longitude   item_location.lngtd_num%type; begin     itemid := 294341;      open c_cursor         select              il.lat_num,             il.lngtd_num,                       item_location il                      il.item_id = itemid ;      close c_cursor;  end; 

does know how either/both of these blocks can return if select above?

i want change anonymous block ... in order remove use of literal bind variable

why think need use anonymous block use bind variable? , both of blocks still have value 294341 hard-coded anyway; select using bind variable within block generating new block every time of improvement on had?

as @haki said many hours ago, cam use prepared statement bind variable:

preparedstatement pstmt = conn.preparestatement(     "select il.lat_num, il.lngtd_num :     + "from item_location il "     + "where il.item_id = ?"); pstmt.setint(1, 294341); 

... , execute query , process result set presumably already. (from reply haki's comment seem confusing prepared statement - java/jdbc construct - stored procedure in database).

here's simple standalone example against demo hr schema's emp table:

import java.sql.; import java.text.; import oracle.jdbc.*; import oracle.jdbc.pool.oracledatasource;

public class jamesgallagher {     public static void main(string args[]) throws sqlexception     {         connection conn;         oracledatasource ds = new oracledatasource();         ds.seturl("jdbc:oracle:thin:scott/oracle@127.0.0.1:1521:orcl");         conn = ds.getconnection();          preparedstatement pstmt = conn.preparestatement(             "select ename, sal emp sal > ?");         pstmt.setint(1, integer.parseint(args[0]));          resultset rs = pstmt.executequery();          while (rs.next())         {             system.out.println(rs.getstring(1) + ": " + rs.getint(2));         }          try { rs.close(); } catch ( exception ex ) {}         try { pstmt.close(); } catch ( exception ex ) {}         try { conn.close(); } catch ( exception ex ) {}         conn = null;     } } 

i can compile javac jamesgallagher.java , execute java jamesgallagher 1500 , prints results based on bound value:
