当我写一个sql时，我能够根据名称查询sql的NA案例分组。 我们可以编写一个sql来满足这两个条件。当“NA”它必须总结所有配置的数据
答案 0 :(得分：0)
您可以使用UNION执行此操作：
SELECT MSISDN, Name, y/N, top, cycle, activationDate, NULL, Sum(PRovisioned), Null
FROM <table>
WHERE top = 'NA'
GROUP BY MSISDN, Name, y/N, top, cycle, activationDate
UNION ALL
SELECT MSISDN,Name,y/N,top,cycle,ActivationDate,Bottom,Provisioned,renewdate
FROM <table>
WHERE top <> 'NA'
那应该让你亲近。我不知道你如何在1280-2048查询中获得GROUP BY'预配'。如果需要，你必须在那里解释逻辑以获得额外的帮助。
