如何在SQL查询where子句中指定多个值？

Question

我目前的查询是：

Select Distinct
  SomeDay.SomeDayID, SomeDay.FolderName, SomeDay.FolderColor
from
  SomeDay, SomeDayEvent
where
  SomeDay.SomeDayID != 4,3,2,1;

Answer 1

我想你想要：

Select Distinct
  SomeDay.SomeDayID, SomeDay.FolderName, SomeDay.FolderColor
from
  SomeDay, SomeDayEvent
where
  SomeDay.SomeDayID not in (4,3,2,1)

Answer 2

这是您的问题所在。

Select Distinct
SomeDay.SomeDayID, SomeDay.FolderName, SomeDay.FolderColor
from 
SomeDay, SomeDayEvent 
where
SomeDay.SomeDayID>4;

Answer 3

这应该是

Select Distinct
   SomeDay.SomeDayID, SomeDay.FolderName, SomeDay.FolderColor
from  
   SomeDay, SomeDayEvent
where
   SomeDay.SomeDayID != 4
and
   SomeDay.SomeDayID != 3
and
   SomeDay.SomeDayID != 2
and
   SomeDay.SomeDayID != 1;
