sql-server - INSERT INTO SELECT 给出 : Column name or number of supplied values does not match table definition

Question

我在执行下面的代码时收到此错误消息。

列名或提供的值数量与表定义不匹配。

       --DROP TABLE #UniqueBuildingUsageFkAndBuildingFk
         CREATE TABLE #UniqueUsageFkAndBuildingFk (
         Building_fk INT NOT NULL 
         ,Usage_fk INT NOT NULL DEFAULT(0)
         );

         ;WITH UnknownUsageFkAndBuildingFkCTE AS (
        SELECT DISTINCT mm.Building_fk, 0 AS Usage_fk FROM Customers.StandardizedRecord sr
        JOIN Customers.MidasMatch mm ON mm.CustomersBuildingNumberKey = sr.CustomersBuildingNumberKey
        WHERE sr.CustomersBuildingNumberKey NOT IN (SELECT DISTINCT emm.CustomersBuildingNumberKey FROM
        [Customers].[CustomersBuildingNumberKeyCustomersUsageXRef] ebu 
        JOIN [Customers].[MidasMatch] emm ON emm.CustomersBuildingNumberKey = ebu.CustomersBuildingNumberKey WHERE emm.Building_fk > 0)
        AND mm.Building_fk > 0 
        ) 
        INSERT INTO #UniqueUsageFkAndBuildingFk 
        SELECT Building_fk, Usage_fk
        FROM UnknownUsageFkAndBuildingFkCTE;

但是当我注释掉 INSERT INTO #UniqueUsageFkAndBuildingFk 行时，我返回了所需的结果集。

我迷路了...

在您的表 #UniqueUsageFkAndBuildingFk 中，您有 3 列(Building_fk、Usage_fk、CustomersBuildingNumberKey)。因此，在插入到该表中时，您必须为这三列指定值

INSERT INTO #UniqueUsageFkAndBuildingFk 
SELECT Building_fk, Usage_fk, 0
FROM UnknownUsageFkAndBuildingFkCTE;

或者您可以在插入中指定列

INSERT INTO #UniqueUsageFkAndBuildingFk (Building_fk, Usage_fk)
SELECT Building_fk, Usage_fk
FROM UnknownUsageFkAndBuildingFkCTE;
