Question

CREATE OR REPLACE FUNCTION totalPatients
RETURN number IS
   total number(2) := 0;
BEGIN
   SELECT count(*) into total
   FROM patient;

   RETURN total;
END;

DECLARE
   c number(2);

   dbms_output.put_line('Total no. of Patients: ' || c);
END;


Error(11,1): PLS-00103: Encountered the symbol "DECLARE"

Answer 1

在函数定义和匿名块之后单独添加一个斜杠/（在单独的行上）。其他一切都应该工作。
