在某些字段上从用户定义的 table 插入数据，其他字段必须使用标量变量

Question

我将如何利用加载数据的用户定义 table，插入到 table 但 table 字段中的 1 个不会使用来自用户定义的数据 Table。我想要一个标量变量来代替它。

@dataTableType是下面的用户自定义table：

CREATE TYPE [dbo].[NewSequenceType] AS TABLE (
    [FK_Sequence] [int] NULL,
    [FK_Status] [int] NULL,
    [FK_Shift] [int] NULL,
    [PK_SequenceType] [int] NULL,
    [TypeName] [varchar](30) NULL,
    [SequenceName] [varchar](100) NULL,
    [SequenceDetails] [varchar](400) NULL,
    [SequenceStatus] [varchar](15) NULL,
    [SequenceShift] [varchar](15) NULL,
    [EmployeeId] [varchar](8) NULL,
    [EquipmentId] [varchar](25) NULL,
    [Comments] [varchar](512) NULL,
    [EnteredDate] [datetime] NULL
)

我的存储过程：

ALTER PROCEDURE [dbo].[spNewInspectionEntry] (@dataTableType NewSequenceType READONLY)
    INSERT INTO dbo.PIT_Inspection (FK_Sequence, FK_Status, FK_Shift, FK_EmployeeName, FK_EquipmentName, Comments, EnteredDate)
        SELECT 
            FK_Sequence, FK_Status, FK_Shift, EmployeeId, 
            EquipmentId, Comments, EnteredDate
        FROM 
            @dataTableType;

我想做什么：

DECLARE @EmployeeIDExists varchar(8);
--Note that I only care about one row, this is Ok.
SELECT TOP 1 @EmployeeIDExists = EmployeeId FROM @dataTableType;

--Retrieve PKEmployeeId
SELECT @EmployeeIdPK = PK_EmployeeName
FROM dbo.PIT_EmployeeName
WHERE EmployeeId = @EmployeeIDExists

--Now I need to insert the value of @EmployeeIdPK? Along with the rest, it needs to replace EmployeeID and EquipmentId, Not sure how to...
INSERT INTO dbo.PIT_Inspection (FK_Sequence, FK_Status, FK_Shift, FK_EmployeeName, FK_EquipmentName, Comments, EnteredDate)
    SELECT 
        FK_Sequence, FK_Status, FK_Shift, EmployeeId, 
        EquipmentId, Comments, EnteredDate
    FROM 
        @dataTableType;

我怎样才能得到@EmployeeIdPK 和其他的一样，它需要替换EmployeeID，我不想要用户定义的EmployeeId table 去那里，我想要变量 @EmployeeIdPK 代替。

Answer 1

您可以在 SELECT 列表中放置任何表达式、变量和文字值。请记住，这些值将针对所有行重复。

含义：

SELECT Field1,
       Field2,
       'hello' AS [LiteralText],
       5 AS [LiteralNumber],
       @Variable AS [ValueFromVariable]
FROM TableName;

将为所有行重复这些文字和变量值。

因此：

INSERT INTO dbo.PIT_Inspection (FK_Sequence, FK_Status, FK_Shift, FK_EmployeeName,
         FK_EquipmentName, Comments, EnteredDate)
    SELECT 
        FK_Sequence, FK_Status, FK_Shift, @EmployeeIdPK, 
        EquipmentId, Comments, EnteredDate
    FROM 
        @dataTableType;
