Hi,
create or replace function bank_head return varchar2 is
v_bankh varchar2(2000) :='';
begin
for i in (select bankname from bank order by bankid)
loop
v_bankh := v_bankh || substr(i.bankname,1,3) || ' ';
end loop;
return v_bankh;
end;
create or replace function bank_detl(p_empno number) return varchar2 is
v_bankc varchar2(2000);
cursor c1 is select bankid from bank;
v_id number;
begin
open c1;
for i in (select bankid from emp1_bank where empno=p_empno order by 1)
loop
loop
fetch c1 into v_id;
exit when c1%notfound;
if i.bankid = v_id then
v_bankc := v_bankc || ' Y ' || ' ';
exit;
else
v_bankc := v_bankc || ' ' || ' ';
end if;
end loop;
end loop;
close c1;
return v_bankc;
exception when others then
return null;
end;
1 select 'emp ',substr(bank_head,1,100) from dual
2 union all
3* select substr(to_char(empno),1,3),substr(bank_detl(empno),1,100) from emp1
SQL> /
'EMP SUBSTR(BANK_HEAD,1,100)
emp ICI HDF SBI SBH
100 Y Y
222 Y Y
333 Y
444 Y
It is Ok With you
