这是代码

DECLARE 
    myBirthday VARCHAR2(20):= TO_CHAR(TO_DATE ('21-jul-1994', 'DD-MM-YYYY'), 'DAY');
    birthday VARCHAR2(20);
BEGIN
    IF myBirthday = 'FRIDAY' THEN
        birthday := 'Your Birthday is on a FRIDAY';
    ELSEIF (myBirthday = 'SATURDAY') THEN
        birthday := 'Your Birthday is on a SATURDAY';
    ELSEIF (myBirthday = 'SUNDAY') THEN
        birthday := 'Your Birthday is on a SUNDAY';
    ELSE
        birthday := 'Your Birthday is on a Weekday';
    END IF;
    DBMS_OUTPUT.PUT_LINE(birthday);
END;

Answer 1

而不是ELSEIF使用ELSIF。

您还需要声明birthday，以便它足够大以容纳您尝试放入的内容。

Answer 2

您的错误是因为您定义了：

birthday VARCHAR2(20);

你正试图用超过20个字符填充它

birthday := 'Your Birthday is on a FRIDAY';
           --1                          27

因此，将变量大小增加到大约30 0r 35 char，如：

 birthday VARCHAR2(35);

应该有效

编辑：正如@WW所说。你应该使用ELSIF
