type type_name is table of varchar2(30) index by
for the above type you have to create a identifier...
for the above type you can use the below methods..like
first , last , prior, next , delege..etc...like this..
if you create a cursor...like
cursor cursor_name is select * from scott.emp;
is there any methods like above to use prior, fist , last ,
next , trim ,etc...
v_sal scott.emp.sal%type := '&P_sal';
cursor cur_name is select sal from scott.emp where sal
between (v_sal-100) and (v_sal +1000);
v_count :=nvl(sql%rowcount ,0);
if v_count = 0 then
dbms_output.put_line('no records are fetch in the given sal
dbms_output.put_line('There is/are '||to_char(v_count)||
' salaries are selected in the given range ');
in the above programm .....for any sal range ....always it
shows the following message..
no records are fetch in the given sal range

1. is it possible to use the cursor atttibutes (%found ,%
rowcount , %isopen , %notfound ) to our user defined cursor
cursor cursor_name is select * from scott.emp
if you use...
cursor_name%found , %rowcount ,%isopen,%notfound...will it
2.what is the difference between the varray and index by
type type_name is table of number(8,3)
index by binary_integer;
first , last , prior , next ,trim are the methods we can
use it for the above type...simillary is there any way to
apply for cursors...
