Question

So the below doesn't work when run. I added the column [Target_Id] INT to my Create Table statement. It now throws the error:

Msg 213, Level 16, State 1, Line 1376
Column name or number of supplied values does not match table definition.

Here's the whole batch:

--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))

But if I split the batch into two parts it works.

Batch 1:

--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
    );

Batch 2:

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))

Anyone know why a single batch fails to drop and create the temp table, but two separate batches works?

Answer 1

这是因为当临时表DDL在同一批中时，您添加的列Target_Id尚未成为表定义的一部分，因此未检测到此元数据。在上一个批次中创建表时，将在执行第二个批次之前检测到您添加的列。要使用尚未添加但将添加到同一批对象中的列，必须按如下所示进行修改后，使用动态SQL访问表。

--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
    );

        VALUES (''SubParam1'',[SubParam1]),
            (''SubParam2'',[SubParam2]),
