INSERT INTO SELECT gives: Column name or number of supplied values does not match table definition

Question

I'm getting this error message when executing the code below.

Column name or number of supplied values does not match table definition.

       --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;

But when I comment out the INSERT INTO #UniqueUsageFkAndBuildingFk line I'm returning the desired resultset.

I'm lost...

Answer 1

In your table #UniqueUsageFkAndBuildingFk you have 3 columns (Building_fk, Usage_fk, CustomersBuildingNumberKey). So while insert into to this table you have to specify values for these three column

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

or you can specify the column in your insert

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