ERREUR à la ligne 17: ORA-06550: ligne 17, colonne 4: PLS-00103: A rencontré le symbole ";" lorsque vous vous attendez à l'une des situations suivantes: si
Le problème est que else et if sont deux opérateurs ici. Puisque vous ouvrez un nouveau "si", vous avez besoin d'une "fin si" correspondante.
Donc:
declare
mark number :=50;
begin
mark :=& mark;
if (mark between 85 and 100) then
dbms_output.put_line('mark is A ');
else
if (mark between 50 and 65) then
dbms_output.put_line('mark is D ');
else
if (mark between 66 and 75) then
dbms_output.put_line('mark is C ');
else
if (mark between 76 and 84) then
dbms_output.put_line('mark is B');
else
dbms_output.put_line('mark is F');
end if;
end if;
end if;
end if;
end;
/
Vous pouvez également utiliser elsif:
declare
mark number :=50;
begin
mark :=& mark;
if (mark between 85 and 100)
then
dbms_output.put_line('mark is A ');
elsif (mark between 50 and 65) then
dbms_output.put_line('mark is D ');
elsif (mark between 66 and 75) then
dbms_output.put_line('mark is C ');
elsif (mark between 76 and 84) then
dbms_output.put_line('mark is B');
else
dbms_output.put_line('mark is F');
end if;
end;
/
L'instruction IF a ces formes dans PL/SQL
:
IF THEN
IF THEN ELSE
IF THEN ELSIF
Vous avez utilisé elseif
qui, en termes de PL/SQL, est incorrect. Cela doit être remplacé par ELSIF
.
