Question

我是SQL Server和DBMS的新手，我在以下查询中遇到了一些问题：查询了一个名为的表的单个记录： MaliciousCodeAlertDocument

这是我的疑问：

UPDATE MaliciousCodeAlertDocument 
SET Discovered = GetDate(), 
    LastUpdated = GetDate(), 
    SourceId = "UP", 
    MalCodeID = 1,
    Title = "UPDATED",
    Origin =  "UP", 
    Type = "UP",
    Feature = "UP",
    Risk = "UP",
    Severity = 1,
    OverallImpact = 1,
    ContagionPotential = 1,
    Wild = "UP",
    AlertStatusID = 1,
    AttributeType = 1,
    DetailLevel = 1  ,
    Language = 1  ,
    Summary = "UP"  ,
    Symptom = "UP"  ,
    TechnicalDescription = "UP"  ,
    MitigatingStrategy = "UP"  ,
    Disinfection = "UP"  ,
    URL = "UP" 
WHERE Id = 11316

当我尝试执行它时，我收到以下错误消息：

Msg 207, Level 16, State 1, Line 1
Invalid column name 'UP'.
Msg 207, Level 16, State 1, Line 1
Invalid column name 'UPDATED'.
Msg 207, Level 16, State 1, Line 1
Invalid column name 'UP'.
Msg 207, Level 16, State 1, Line 1

Msg 207, Level 16, State 1, Line 1

Msg 207, Level 16, State 1, Line 1

Msg 207, Level 16, State 1, Line 1
Invalid column name 'UP'.
Msg 207, Level 16, State 1, Line 1
Invalid column name 'UP'.
Msg 207, Level 16, State 1, Line 1
Invalid column name 'UP'.
Msg 207, Level 16, State 1, Line 1
Invalid column name 'UP'.

有什么问题？我该如何解决？

使用双引号使SQL Server认为引号中的值是一列，但看起来您正在尝试将其更新为文本值。如果您使用单引号，SQL将识别您要将该值插入到字段中，并应正确加载它。

为什么此更新查询不起作用？
