Sql 每个分支机构的前三项记录

我需要为公司每个分支机构的前三名recordcount和sum编写查询，我有分支机构客户和合同表

首先，创建如下表：

CREATE TABLE [dbo].[Branches](
    [Id] [int] NOT NULL,
    [CompanyId] [int] NULL,
    [Something] [int] NULL,
 CONSTRAINT [PK_Table_5] PRIMARY KEY CLUSTERED 
(
    [Id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO

SELECT result.Companyid, SUM(result.Something) [Sum], (SELECT COUNT(*) FROM Branches WHERE CompanyId = result.companyid) AS [Count]
    FROM (
        SELECT companyid, Something, Rank() 
          OVER (PARTITION BY CompanyId
                ORDER BY id DESC ) AS Rank
        FROM Branches
        ) result WHERE Rank <= 3
GROUP BY CompanyId

然后，在其中插入一些数据：

INSERT [dbo].[Branches] ([Id], [CompanyId], [Something]) VALUES (1, 1, 10)
GO
INSERT [dbo].[Branches] ([Id], [CompanyId], [Something]) VALUES (2, 1, 15)
GO
INSERT [dbo].[Branches] ([Id], [CompanyId], [Something]) VALUES (3, 1, 20)
GO
INSERT [dbo].[Branches] ([Id], [CompanyId], [Something]) VALUES (4, 1, 25)
GO
INSERT [dbo].[Branches] ([Id], [CompanyId], [Something]) VALUES (5, 1, 22)
GO
INSERT [dbo].[Branches] ([Id], [CompanyId], [Something]) VALUES (6, 2, 50)
GO
INSERT [dbo].[Branches] ([Id], [CompanyId], [Something]) VALUES (7, 2, 32)
GO
INSERT [dbo].[Branches] ([Id], [CompanyId], [Something]) VALUES (8, 2, 30)
GO
INSERT [dbo].[Branches] ([Id], [CompanyId], [Something]) VALUES (9, 2, 10)
GO

最后，您的查询将如下所示：

CREATE TABLE [dbo].[Branches](
    [Id] [int] NOT NULL,
    [CompanyId] [int] NULL,
    [Something] [int] NULL,
 CONSTRAINT [PK_Table_5] PRIMARY KEY CLUSTERED 
(
    [Id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO

SELECT result.Companyid, SUM(result.Something) [Sum], (SELECT COUNT(*) FROM Branches WHERE CompanyId = result.companyid) AS [Count]
    FROM (
        SELECT companyid, Something, Rank() 
          OVER (PARTITION BY CompanyId
                ORDER BY id DESC ) AS Rank
        FROM Branches
        ) result WHERE Rank <= 3
GROUP BY CompanyId
