这在SQL中可行吗？

我有一个包含一些数据的表格，需要在屏幕上以特定格式显示。

表格结构如下：

CREATE TABLE [dbo].[JobSheet](
    [JobSheetID] [bigint] IDENTITY(1,1) NOT NULL,
    [SheetNumber] [bigint] NULL,
    [JobSheetDate] [datetime] NULL,
    [ContractID] [bigint] NULL,
    [ContractCode] [varchar](50) NULL,
    [ContractTitle] [varchar](100) NULL,
    [ProjectID] [bigint] NULL,
    [ProjectCode] [varchar](50) NULL,
    [ProjectTitle] [varchar](100) NULL,
    [JobID] [bigint] NULL,
    [JobCode] [varchar](50) NULL,
    [JobTitle] [varchar](100) NULL,
    [SageDatabaseID] [bigint] NULL,
    [SageDatabaseName] [varchar](50) NULL,
    [EnteredByID] [bigint] NULL,
    [EnteredByUsername] [varchar](50) NULL,
    [DocumentStatus] [varchar](50) NULL,
    [Deleted] [bit] NULL,
    [Reference] [varchar](50) NULL,
    [UpdatedDate] [datetime] NULL,
    [UpdatedUser] [varchar](50) NULL,
    [SentToSage] [bit] NULL,
    [UpdateStatus] [varchar](50) NULL,
 CONSTRAINT [PK_JobSheet] PRIMARY KEY CLUSTERED 
(
    [JobSheetID] 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

CREATE TABLE [dbo].[JobSheetLine](
    [JobSheetLineID] [bigint] IDENTITY(1,1) NOT NULL,
    [JobSheetID] [bigint] NULL,
    [LineType] [varchar](50) NULL,
    [TSHumanResourceID] [bigint] NULL,
    [SageDatabaseID] [bigint] NULL,
    [Surname] [varchar](50) NULL,
    [Initial] [varchar](1) NULL,
    [TimeOn] [datetime] NULL,
    [TimeOff] [datetime] NULL,
    [Deleted] [bit] NULL,
    [B1] [decimal](18, 5) NULL,
    [B15] [decimal](18, 5) NULL,
    [B2] [decimal](18, 5) NULL,

    [T] [decimal](18, 5) NULL,
    [TS] [decimal](18, 5) NULL,
    [TT] [decimal](18, 5) NULL,
    [TP] [decimal](18, 5) NULL,
    [OT] [decimal](18, 5) NULL,
    [OS] [decimal](18, 5) NULL,
    [D] [decimal](18, 5) NULL,
    [POA] [decimal](18, 5) NULL,
    [PT1] [decimal](18, 5) NULL,
    [PT2] [decimal](18, 5) NULL,
    [CustomCostRate1] [decimal](18, 5) NULL,
    [CustomCostRate1ID] [bigint] NULL,
    [CustomCostRate2] [decimal](18, 5) NULL,
    [CustomCostRate2ID] [bigint] NULL,
    [CustomCostRate3] [decimal](18, 5) NULL,
    [CustomCostRate3ID] [bigint] NULL,
    [CustomCostRate4] [decimal](18, 5) NULL,
    [CustomCostRate4ID] [bigint] NULL,
    [CustomCostRate5] [decimal](18, 5) NULL,
    [CustomCostRate5ID] [bigint] NULL,
    [CustomCostRate6] [decimal](18, 5) NULL,
    [CustomCostRate6ID] [bigint] NULL,
    [UpdatedDate] [datetime] NULL,
    [UpdatedUser] [varchar](50) NULL,
    [RejectReason] [varchar](255) NULL,
    [CurrentStepApprovalCount] [bigint] NULL,
    [CustomRouteID] [bigint] NULL,
    [CustomRoute] [bit] NULL,
    [CurrentStep] [bigint] NULL,
    [WaitingForType] [varchar](50) NULL,
    [WaitingForID] [bigint] NULL,
    [RequestedByID] [bigint] NULL,
    [LineStatus] [varchar](50) NULL,
 CONSTRAINT [PK_JobSheetLine] PRIMARY KEY CLUSTERED 
(
    [JobSheetLineID] 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

在这样的屏幕上输入数据，可以更好地显示JobSheetLineTable的格式： enter image description here

我需要获取数据所需的格式如下面的截图： enter image description here

需要员工过滤数据（JobSheetLine表中的RequestedByID） 以及每个独特的合同和项目以及成本费率（成本费率从B1，B15，B2等一直到CustomCostRate6）。

每个费用率的总小时数需要每天。

我已经到了下面的查询，直到我重新开始这不会起作用。我认为问题是由于成本率是JobSheetLine表中的Columns引起的，但是所需的输出将成本率作为单个列，并且行和值显示在行上。

我研究了在SQL中使用PIVOT关键字，但是我无法弄清楚我在做什么。

这是我到目前为止提出的查询（无法正常工作）

DECLARE @Deleted AS BIT
DECLARE @RequestedByID AS BIGINT
DECLARE @WeekStartDate AS DATETIME
DECLARE @WeekEndDate AS DATETIME
DECLARE @WaitingForUserID AS BIGINT
DECLARE @WaitingForUserTypeID AS BIGINT
DECLARE @WaitingForTypeUser AS VARCHAR(50)
DECLARE @WaitingForTypeUserType AS VARCHAR(50)

SET @Deleted = 0
SET @RequestedByID = 2
SET @WeekStartDate = '2011/05/23 00:00'
SET @WeekEndDate = '2011/05/29 00:00'

现在可以用数据结构实现我想要的输出吗？我宁愿在SQL中进行所有计算，因为它更快，但我可以在C＃中进行一些计算，因为这是一个asp.net项目。

Simen S.建议回答这个问题。需要将表格标准化为以下格式：

正如我对原始问题的评论中所建议的那样，我认为正常化是一个很好的长期解决方案。
