tSQL NOT IN查询

我想获取[interaction]表的ID,但这些ID不能等于[EmailOUT]表.我无法编写查询.

Select ID from EmailOut         
where ID NOT IN         
   (select ID from
    [172.28.101.120].[GenesysIS].dbo.interactions 
    where media_type = 'email'
    and type = 'Outbound')

类似的东西.我想在交互表中输出外发电子邮件,但这些电子邮件可能存在于EmailOut表中.我想删除它们.出站电子邮件数约为300,但此查询结果应小于300

解决方法

如果你想获得[interaction]表的ID,你似乎应该反转你的查询：

select ID from
[172.28.101.120].[GenesysIS].dbo.interactions 
where media_type = 'email'
and type = 'Outbound'
AND ID NOT IN (SELECT ID FROM EmailOut)
