Hello,
In my PL/SQL code I have a composite variable of ROWTYPE and I try to access
the variable component using another variable, but I got an error:
"PLS-00302: component 'field_name' must be declared".
The code is:
declare
cursor c1 is select * from old;
old_row c1%ROWTYPE;
cursor c2 is select * from new;
new_row c2%ROWTYPE;
cursor c3 is select column_name from user_tab_columns where table_name =
'OLD';
field_name c3%ROWTYPE;
begin
dbms_output.enable;
open c1;
open c2;
open c3;
loop
fetch c1 into old_row;
fetch c2 into new_row;
exit when (c1%notfound or c2%notfound);
end loop;
loop
fetch c3 into field_name;
If (old_row.field_name = new_row.field_name) then --error in this line!
dbms_output.put_line('SAME VALUE');
else
dbms_output.put_line('DIFFERENT VALUE');
end if;
exit when c3%notfound;
end loop;
end;
How can I fix the problem??
Thanks.
