I have a stored procedure in Oracle and I'm using an out parameter in it.. I want to know how to display the output in Toad..
You just need to declare a variable to store the value in, and then do whatever you want with the data afterwards. If you are just wanting to see the output, dbms_output is probably the easiest way to go:
declare
-- declare variable to store out data in. Make sure datatype is correct
v_out VARCHAR2(50);
begin
-- call procedure, assigning value of out parameter to variable you declared
my_proc(
p_in => 3,
p_out => v_out
);
-- display value now in variable
dbms_output.put_line('Value of p_out: '||v_out);
end;
