calling oracle procedures in java

[subbaraju nadimpalli]

hi

i am trying to call oracle procedure in java and it aslo running without errors but i couldn't get the correct results.

i created one procedure in oracle using cursors beacue it retrives more than one record form table.it shows only last record when we call the procedure in java. here the code.

oracle procedure

create or replace procedure Proc_SearchStdInfo_ByName(id out varchar,name in out varchar,add
out varchar,year out varchar ) is
cursor Cursor_SearchByName(name student.sname%type) is select sid,sname,sadd,syear from student where sname=name;
begin
open Cursor_searchByName(name);
loop
fetch Cursor_SearchByName into id,name,add,year;
exit when Cursor_SearchByName%notfound;
---dbms_output.put_line(id||' '||name||' '||add||' '||year);
end loop;
close Cursor_SearchByName;
end Proc_SearchStdInfo_ByName;

i have written code in java like
Student std=new Student();
CallableStatement cs=con.prepareCall("{call Proc_SearchStdInfo_ByName(?,?,?,?)}");
cs.registerOutParameter(1,Types.VARCHAR);
cs.registerOutParameter(2,Types.VARCHAR);
cs.registerOutParameter(3,Types.VARCHAR);
cs.registerOutParameter(4,Types.VARCHAR);
cs.setString(2,sname);
ResultSet rs=cs.executeQuery();
if(rs!=null)
{
while(rs.next())
{
std.setID(cs.getString(1));
std.setName(cs.getString(2));
std.setAdd(cs.getString(3));
std.setYear(cs.getString(4));
}
}

it shows only one record that is the last result of table.

how can we retrive all results from table using oracle procedure

Even if you execute the procedure from Oracle you get only the last record values fetched into the out parameters before closing the cursor.I mean if you put "dbms_output.put_line(id||' '||name||' '||add||' '||year);" statement after "end loop;" and before "close Cursor_SearchByName;" statement you will know that.

If you would like to iterate through the cursor from the java code, then you need to have the cursor as out parameter.

Hope this may help you.
