CASE in definition of cursor
Why isn't CASE supported by PL/SQL in definition of cursor? It doesn't work.
Why isn't CASE supported by PL/SQL in definition of cursor? I used the following command:
declare
temp varchar2(100);
cursor cDet is
select
case when length('pippo - pluto - paperino')>5 then 'OK' else 'NO'
END
from dual;
begin
open cDet;
fetch cDet into temp;
WHILE cDet%found LOOP
dbms_output.put_line(temp);
fetch cDet into temp;
end loop;
close cDet;
end;
It doesn't work, but if I use the following one it works fine:
select
case when length('pippo - pluto - paperino')>5 then 'OK' else 'NO'
END
from dual
Why?
The case statement is supported by PL/SQL. The problem may be with your PL/SQL procedure. The below procedure works:
declare
temp varchar2(100);
cursor cdet is
select
case
when length('pippo - pluto - paperino' )>5 then
'OK'
else
'No'
end
from dual;
begin
open cdet;
fetch cdet into temp;
-- while cdet%found loop
dbms_output.put_line('temp '||temp);
-- fetch cdet into temp;
-- end loop;
close cdet;
end;
