通过调整单个列的不同值来进行多行更新

Question

道歉说我是SQL方面的新手。所以，让我把下面的场景放在学生桌上。

> Roll_Number   Student_Name    isActive     Relieved_Date 
> ---------------------------------------------------------- 
> 101            John             True         NULL 
> 102            Bob              False        2015-01-20 00:00:00.000 
> 103            Joe              True         NULL 
> 104            Mike             True         NULL
> 105            Steve            False        2014-04-12 00:00:00.000
> 106            Lia              True         NULL 
> 107            Maya             True         NULL 
> 108            Gordon           True         NULL

现在我想将forActive列更新为False，其中Relieved_Date = 2015-01-20 for Roll_Number - 101,104,107,108

非常感谢您能帮助我。

Answer 1

UPDATE Student
SET Relieved_Date = '2015-01-20', 
    isActive = 'False'
WHERE Roll_Number IN (101, 104, 107, 108)

Answer 2

使用{/ 1}}语句，如

UPDATE

可能是错误的解释但是你说你想设置update student set isActive = false where Roll_Number in (101, 104, 107, 108) and Relieved_Date = '2015-01-20 00:00:00.000'; 如果是，那么也包括Relieved_Date = 2015-01-20语句

SET

Answer 3

这有助于......

update YourTable
set isActive = 'False', Relieved_Date = '2015-01-20 00:00:00.000'
where Roll_Number in (101,104,107,108)
