在批次插入运行时不会放弃临时表

Question

所以下面不工作时运行。我加列[Target_Id] INT我Create Table声明。现在抛出的错误：

消息213，级别16，状态1，1376线 列名或提供值的数目不匹配表定义。

这里是整批：

--FactSite
IF OBJECT_ID('tempdb..#factSite', 'U') IS NOT NULL
    DROP TABLE #factSite;

CREATE TABLE #factSite
(
    [ID] INT,
    [Target_Id] INT,
    [SYS_CHANGE_OPERATION] NVARCHAR(1),
    DimSite_Id INT,
    DimSubSite_Id INT,
    DimSubParameters_Id INT
);

WITH cteUpivotFactSite AS
(
    SELECT [ID], [SYS_CHANGE_OPERATION], [SiteID], [SubSiteID], 
        [SubParameterVal] AS [SubParameter]
    FROM Staging.AppsFlyerBasic
    CROSS APPLY (
        VALUES ('SubParam1',[SubParam1]),
            ('SubParam2',[SubParam2]),
            ('SubParam3',[SubParam3]),
            ('SubParam4',[SubParam4]),
            ('SubParam5',[SubParam5])
    ) x ([DimensionVal],[SubParameterVal])
)
INSERT INTO #factSite
SELECT src.[ID], NULL, src.[SYS_CHANGE_OPERATION], 
    site.[ID] AS DimSite_Id, subSite.ID AS DimSubSite_Id,
    subParameters.[ID] AS DimParameters_Id
FROM cteUpivotFactSite AS src
INNER JOIN AppsFlyer.DimSite AS site
ON (src.[SiteID] = site.[Name] OR (src.[SiteID] IS NULL AND site.[Name] IS NULL))
INNER JOIN AppsFlyer.DimSubSite AS subSite
ON (src.[SubSiteID] = subSite.[Name] OR (src.[SubSiteID] IS NULL AND subSite.[Name] IS NULL))
INNER JOIN AppsFlyer.DimSubParameters AS subParameters
ON (src.[SubParameter] = subParameters.[Name] OR (src.[SubParameter] IS NULL AND subParameters.[Name] IS NULL))

但是，如果我分裂批次分为两个部分它的工作原理。

第1批：

--FactSite
    IF OBJECT_ID('tempdb..#factSite', 'U') IS NOT NULL
        DROP TABLE #factSite;
    CREATE TABLE #factSite
    (
        [ID] INT,
        [Target_Id] INT,
        [SYS_CHANGE_OPERATION] NVARCHAR(1),
        DimSite_Id INT,
        DimSubSite_Id INT,
        DimSubParameters_Id INT
    );

第2批：

WITH cteUpivotFactSite AS
    (
        SELECT [ID], [SYS_CHANGE_OPERATION], [SiteID], [SubSiteID], 
            [SubParameterVal] AS [SubParameter]
        FROM Staging.AppsFlyerBasic
        CROSS APPLY (
            VALUES ('SubParam1',[SubParam1]),
                ('SubParam2',[SubParam2]),
                ('SubParam3',[SubParam3]),
                ('SubParam4',[SubParam4]),
                ('SubParam5',[SubParam5])
        ) x ([DimensionVal],[SubParameterVal])
    )
    INSERT INTO #factSite
    SELECT src.[ID], NULL, src.[SYS_CHANGE_OPERATION], 
        site.[ID] AS DimSite_Id, subSite.ID AS DimSubSite_Id,
        subParameters.[ID] AS DimParameters_Id
    FROM cteUpivotFactSite AS src
    INNER JOIN AppsFlyer.DimSite AS site
    ON (src.[SiteID] = site.[Name] OR (src.[SiteID] IS NULL AND site.[Name] IS NULL))
    INNER JOIN AppsFlyer.DimSubSite AS subSite
    ON (src.[SubSiteID] = subSite.[Name] OR (src.[SubSiteID] IS NULL AND subSite.[Name] IS NULL))
    INNER JOIN AppsFlyer.DimSubParameters AS subParameters
    ON (src.[SubParameter] = subParameters.[Name] OR (src.[SubParameter] IS NULL AND subParameters.[Name] IS NULL))

任何人都知道为什么单批不下降，并创建临时表，而是两个不同批次的作品？

Answer 1

这是因为你添加的列，Target_Id，还不是表定义的一部分，当临时表DDL是在同一批次，因此，该元数据没有感觉到。当在先前的间歇在创建表时，执行第二批之前检测所添加的列中。要使用还没有，但将列添加到对象在同一批次必须使用动态SQL来访问表后，修改完成后如下。

--FactSite
    IF OBJECT_ID('tempdb..#factSite', 'U') IS NOT NULL
        DROP TABLE #factSite;
    CREATE TABLE #factSite
    (
        [ID] INT,
        [Target_Id] INT,
        [SYS_CHANGE_OPERATION] NVARCHAR(1),
        DimSite_Id INT,
        DimSubSite_Id INT,
        DimSubParameters_Id INT
    );

declare @query nvarchar(2000)

set @query = N'
WITH cteUpivotFactSite AS
(
    SELECT [ID], [SYS_CHANGE_OPERATION], [SiteID], [SubSiteID], 
        [SubParameterVal] AS [SubParameter]
    FROM Staging.AppsFlyerBasic
    CROSS APPLY (
        VALUES (''SubParam1'',[SubParam1]),
            (''SubParam2'',[SubParam2]),
            (''SubParam3'',[SubParam3]),
            (''SubParam4'',[SubParam4]),
            (''SubParam5'',[SubParam5])
    ) x ([DimensionVal],[SubParameterVal])
)
INSERT INTO #factSite
SELECT src.[ID], NULL, src.[SYS_CHANGE_OPERATION], 
    site.[ID] AS DimSite_Id, subSite.ID AS DimSubSite_Id,
