Sql server HAVING子句中count（）=1的TSQL limit记录

好的，我有3个表，它们在指定的键上链接

account (accountnumber)
package (packageid, accountnumber)
hostdomain (packageid)

我需要得到所有帐户，只有一个域，这里是我的查询到目前为止，但它是返回所有域。我做错了什么

select 
    domainname,
    resellerAccountNumber,
    a.accountnumber,
    companyname,
    firstname,
    lastname,
    primaryemail,
    HomePhone
    workphone
FROM account a 
INNER JOIN Package p on p.AccountNumber = a.AccountNumber
INNER JOIN hostdomain hd ON HD.packageId = p.packageID 
GROUP BY 
    domainname, reselleraccountnumber, a.accountnumber, companyname, 
    firstname,lastname,primaryemail, HomePhone,workphone, domainaliasId   
HAVING COUNT(domainname) =1 
    AND domainAliasID = 0 
    AND ResellerAccountNumber in ('','LNC','CFMXHOSTING')

---

在HAVING子句中仅使用聚合：

WHERE
    domainAliasID = 0 
    AND ResellerAccountNumber in ('','LNC','CFMXHOSTING')
GROUP BY
    domainname, reselleraccountnumber, a.accountnumber,
    companyname,firstname,lastname,primaryemail, HomePhone,
    workphone, domainaliasId   
HAVING COUNT(domainname) = 1 

---

您正在按太多字段进行聚合。我想你想要这样的东西：

select min(domainname) as domainname, resellerAccountNumber,
       a.accountnumber, companyname, firstname, lastname, primaryemail,
       HomePhone, workphone
FROM account a INNER JOIN
     Package p
     on p.AccountNumber = a.AccountNumber INNER JOIN
     hostdomain hd ON HD.packageId = p.packageID 
GROUP BY reselleraccountnumber, a.accountnumber, companyname, firstname,
         lastname, primaryemail, HomePhone, workphone, domainaliasId   
HAVING COUNT(domainname) = 1 AND
       domainAliasID = 0 AND
       ResellerAccountNumber in ('','LNC','CFMXHOSTING');

---

我通过从

组中删除了
域名
（并进行了相关更改）。我不知道如何处理
domainaliasid
，因为您的问题没有提到任何关于过滤数据的内容，只是将其聚合。您可能希望删除它以获得所需的内容。
是否应该
和domainAliasID=0以及（'''LNC'，'CFMXHOSTING'）中的RebelerAccountNumber
不在where子句中，而不是在have中？
