【解决方案1】：

第二个是正确的。

AND (Call_Type_vod__c != 'Call Only' 
AND Call_Type_vod__c != 'Event Only' 
AND Call_Type_vod__c != 'Event Detail')

我认为您想检索那些 'Call_Type_vod__c' 值不是这些值的行 ('Call Only', 'Event Only', 'Event Detail') 。所以第二个会起作用。

第一个查询将返回所有行

AND (Call_Type_vod__c != 'Call Only' 
OR Call_Type_vod__c != 'Event Only' 
OR Call_Type_vod__c != 'Event Detail')

【解决方案2】：

查询之间的唯一区别在于嵌套 AND 条件

AND (Call_Type_vod__c != 'Call Only' 
  OR Call_Type_vod__c != 'Event Only' 
  OR Call_Type_vod__c != 'Event Detail')

AND (Call_Type_vod__c != 'Call Only' 
  AND Call_Type_vod__c != 'Event Only' 
  AND Call_Type_vod__c != 'Event Detail')

这完全取决于您的数据模型以及您对此查询结果的期望。
