选择给出不同结果的查询

Question

我已经编写了选择以下查询，但令人惊讶的是，查询中的任何错误都给出了不同的结果。请告诉我。询问：

Select count(*) Count from conflux.dbo.SABR_Master M 
        Where M.Email in (
        select top 26 Email from conflux.dbo.SABR_Master L 
        where (L.titleid In (Select titleid From sabr_titlemasters Where IsDisplay=1 And  title like '%Account Executive%' OR title like '%Account Manager%' OR title like '%Accounts Manager%' OR title like '%admin%'  ))
        ) and M.Email NOT IN (select Email from [sample client].dbo.Comm_CompanyData)

Answer 1

试试这个，

Select  count(*) Count 
from    conflux.dbo.SABR_Master M 
Where   M.Email in (select  top 26 
                            L.Email 
                    from conflux.dbo.SABR_Master L 
                    where (L.titleid In (   Select  titleid 
                                            From    sabr_titlemasters 
                                            Where   IsDisplay=1 And  
                                                    (title like '%Account Executive%' OR 
                                                    title like '%Account Manager%' OR 
                                                    title like '%Accounts Manager%' OR 
                                                    title like '%admin%')))
                    ORDER BY L.Email) and 
        M.Email NOT IN (select  Email 
                        from [sample client].dbo.Comm_CompanyData)

我在您的标题两边添加了括号，例如“OR”和“订购依据”，以保持您的 26 封电子邮件相同。如果未指定 order by，数据库可能会以随机顺序返回它们，这可能会给出不同的结果。
