Question

我想从表中选择除一行之外的所有值数据。我该怎么做？

table = teachers
headers = TeacherID, Password, FirstName, Surname
TeacherID = teacher

当我尝试

时

SELECT * 
FROM teachers 
EXCEPT 
SELECT * 
FROM teachers 
WHERE TeacherID = 'teacher'

我收到错误

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SELECT * FROM teachers WHERE TeacherID = teacher LIMIT 0, 30' at line 1

Answer 1

这将选择列TeacherID不包含值teacher

的所有行

Select * from teachers where TeacherID != 'teacher'

我不确定您的列TeacherID是否为字符串，如果是，请不要将其命名为ID。 ID通常是int数据类型。

如果要选择列TeacherID包含值teacher的所有记录，请执行此操作

SELECT * 
FROM teachers 
WHERE TeacherID = 'teacher'

Answer 2

你应该

select * from teachers where TeacherID != 'teacher'

OR

select * from teachers where TeacherID not in ('teacher','teacher1','teacher2')

SQL select *来自教师，除了teacherID = teacher
