Help needed on table type datatype.

Question

Hi,
I have written the following code,
declare
type t is table of emp.empno%type index by binary_integer;
y t;
begin
select empno bulk collect into y
from emp where 1 = 1;
dbms_output.put_line(y.count);
exception
when others then
dbms_output.put_line(SQLERRM);
end;
now i want to print the values from the table type variable y. how can i do that.
Regards
Jhansi

Answer 1

You reference record elements using dot notation: record.field
You reference collection elements using parenthesis notation: collection(element)
So you example might work like this:
declare
  type t is table of emp.empno%type index by binary_integer;
  y t;
begin
  select empno bulk collect into y
  from emp where 1 = 1;
  dbms_output.put_line('count='||y.count);
  dbms_output.put_line('Empno in element 1 is '||y(1));
end; a couple of additional comments
When you post code, you can enclose it with the markup tag { code } but without the space between the curly brackets and the key word code
These tags will format everything between them usign a fixed pitch font making it more readable.
try not to use an EXCEPTION WHEN OTHERS
usually, you don't want to trap and handle ANY exception.
If there is a specific exception that you want to trap and handle in your code put that handler in your code, otherwise let and exception propagate up to your SQLPlus or SQLDeveloper calling program.
