Question

有人可以告诉我我做错了什么，如果我能得到期望的结果...... （请记住这是VIEW）

SELECT
      [Id]
    , [Nome]
    , [Estado]
    , (SELECT COUNT(EstProc) FROM LoginsImp AS LI WHERE (EstProc = 'A1.' OR EstProc = 'A2.') AND LI.LogImpFiles_Id = LIF.Id) AS ItemsProcessamento
    , (SELECT COUNT(EstProc) FROM LoginsImp AS LI WHERE EstProc = 'A3.' AND LI.LogImpFiles_Id = LIF.Id) AS ItemsErroProcessamento
    , (SELECT COUNT(EstProc) FROM LoginsImp AS LI WHERE (EstProc= 'A4' OR EstProc= 'A5') AND LI.LogImpFiles_Id= LIF.Id) AS ItemSucessoProcessamento
    , SUM(ItemsErroProcessamento + ItemSucessoProcessamento) AS [ItemsProcessados]
    , [CreatedOn]
    , [CreatedBy]
FROM
    [dbo].[LogImpFiles] AS LIF
GROUP BY 
    [Id], Nome, Estado, CreatedOn, CreatedBy

结果如下：

1   TesteImport1        6   2   3   0   2015-08-04 15:41:41.5130000 110032797

我期待这样的事情：

1   TesteImport1        6   2   3   **5**   2015-08-04 15:41:41.5130000 110032797

Answer 1

我很想说“这只是你的数据”。也就是说，您的问题没有足够的信息。

但是，我怀疑问题是NULL值。如果任一值为+，则NULL会返回NULL。所以，试试这个：

SUM(COALESCE(ItemsErroProcessamento, 0) + COALESCE(ItemSucessoProcessamento, 0)
   ) AS [ItemsProcessados]

Answer 2

使用JOIN进行条件聚合而不是子查询。正如JamesZ所指出的，SUM不会使用列别名。

SELECT
    [Id]
    , [Nome]
    , [Estado]
    , COUNT(CASE WHEN LI.EstProc = 'A1.' OR LI.EstProc = 'A2.' THEN LI.EstProc END) AS ItemsProcessamento
    , COUNT(CASE WHEN LI.EstProc = 'A3.' THEN LI.EstProc END) AS ItemsErroProcessamento
    , COUNT(CASE WHEN LI.EstProc= 'A4' OR LI.EstProc= 'A5' THEN LI.EstProc END) AS ItemSucessoProcessamento
    , SUM(CASE WHEN LI.EstProc IN('A1.', 'A2.', 'A4', 'A5') THEN 1 ELSE 0 END) AS [ItemsProcessados]
    , [CreatedOn]
    , [CreatedBy]
FROM [dbo].[LogImpFiles] AS LIF
LEFT JOIN LoginsImp LI
    ON .LogImpFiles_Id = LIF.Id
GROUP BY [Id], Nome, Estado, CreatedOn, CreatedBy

SELECT

    , [Nome]
    , [Estado]
    , ItemsProcessamento
    , ItemsErroProcessamento
    , ItemSucessoProcessamento
    , SUM(ItemsErroProcessamento + ItemSucessoProcessamento) AS [ItemsProcessados]
    , [CreatedOn]
    , [CreatedBy]
FROM
(
SELECT
      [Id]
    , [Nome]
    , [Estado]
    , (SELECT COUNT(EstProc) FROM LoginsImp AS LI WHERE (EstProc = 'A1.' OR EstProc = 'A2.') AND LI.LogImpFiles_Id = LIF.Id) AS ItemsProcessamento
    , (SELECT COUNT(EstProc) FROM LoginsImp AS LI WHERE EstProc = 'A3.' AND LI.LogImpFiles_Id = LIF.Id) AS ItemsErroProcessamento
    , (SELECT COUNT(EstProc) FROM LoginsImp AS LI WHERE (EstProc= 'A4' OR EstProc= 'A5') AND LI.LogImpFiles_Id= LIF.Id) AS ItemSucessoProcessamento
    , SUM(ItemsErroProcessamento + ItemSucessoProcessamento) AS [ItemsProcessados]
    , [CreatedOn]
    , [CreatedBy]
FROM
    [dbo].[LogImpFiles] AS LIF
GROUP BY 
    [Id], Nome, Estado, CreatedOn, CreatedBy
)BASE
GROUP BY 
    [Id], Nome, Estado, , ItemsProcessamento, ItemsErroProcessamento, ItemSucessoProcessamento,CreatedOn, CreatedBy

SQL Server中SELECT ... WHERE的求和结果
