我的任务是删除任何姓名以 Z 或 z 开头的教职人员。我尝试了一些我一直在研究的代码，但在使其工作时遇到困难。以下是创建表、插入表以及最后删除条目的代码:
CREATE TABLE Faculty (
FacultyID int primary key,
FirstName varchar(30),
LastName varchar(30),
EMail varchar(60),
BirthDate DATE,
Numbr_Courses int
);
insert into Faculty
values (10579, 'John','Spelling','<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="2e445d5e4b42424740496e484f4d5b425a57005b435b4d004b4a5b" rel="noreferrer noopener nofollow">[email protected]</a>','1983-06-26','5');
insert into Faculty

DELETE FROM Faculty WHERE LastName='Z%'
我以为最后的语句会删除代码，但它并没有删除它，只是保持不变。任何帮助将不胜感激。
最佳答案
DELETE FROM Faculty WHERE LastName LIKE 'Z%'
使用通配符 % 时，您需要使用 LIKE 而不是 =。
