SQL组两次，不同的行

Question

我正在使用SQL Azure。我试图将一组结果分组两次，以便用户名字段是唯一的。在我的结果中，相同的行多次出现，并且具有不同的事务计数值。

这是我的代码：

select settings.UserName, SUM(TransactionCount) as TransactionCount, settings.SettingValue as    Sku, CASE 
WHEN settings.SettingValue = 'cccmicro' AND TransactionCount > 1800 THEN 'True'
WHEN settings.SettingValue = 'cccsub1' AND TransactionCount > 6000 THEN 'True'
WHEN settings.SettingValue = 'cccsub2' AND TransactionCount > 18000 THEN 'True'
WHEN settings.SettingValue = 'cccsub3' AND TransactionCount > 30000 THEN 'True' 
ELSE 'False'
END As [Over]
from jma_qb_trans_count trans
Inner Join jma_settings settings on settings.UserName = trans.UserName
where settings.SettingName = 'QB:JMAWebStoreSku' and settings.SettingValue != ''
Group by settings.UserName, settings.SettingValue, settings.SettingName, TransactionCount
Order By settings.UserName

这是我的数据：

以下是我所寻求的：

用户名：james.dick TransactionCount：8 Sku：cloudcartconnectorlicense 结束：错误

Answer 1

请尝试以下代码。我认为它会像你问的那样奏效。

select 

settings.UserName, 
CASE 
WHEN settings.SettingValue = 'cccmicro' AND TransactionCount > 1800 THEN 'True'
WHEN settings.SettingValue = 'cccsub1' AND TransactionCount > 6000 THEN 'True'
WHEN settings.SettingValue = 'cccsub2' AND TransactionCount > 18000 THEN 'True'
WHEN settings.SettingValue = 'cccsub3' AND TransactionCount > 30000 THEN 'True' 
ELSE 'False'
END As [Over],
SUM(TransactionCount) as TransactionCount, 
settings.SettingValue as Sku

from jma_qb_trans_count trans
Inner Join jma_settings settings on settings.UserName = trans.UserName
where settings.SettingName = 'QB:JMAWebStoreSku' and settings.SettingValue != ''
Group by 1,2

您的分组将分割结果放入选择部分，您会看到   为什么查询无法正常工作。

Group by settings.UserName, settings.SettingValue, settings.SettingName, TransactionCount
