【问题描述】：

我将临时表name? 作为存储过程的输出，并将创建的临时表的name 作为输入参数传递给另一个存储过程。

我想从 @CalculationGuidTempTableName VARCHAR 中选择 Guid，然后插入到 @CalcsGuids。

这是我的存储过程：

CREATE PROCEDURE [dbo].[ret_Reports_ProxyVoucherAccounting]
    (@CalculationGuidTempTableName VARCHAR(32))
AS
    DECLARE @CalcsGuids TABLE ([Guid] UNIQUEIDENTIFIER PRIMARY KEY)

    --INSERT INTO @CalcsGuids (SELECT * FROM  + @CalculationGuidTempTableName)
    --DROP TABLE  @CalculationGuidTempTableName
    WITH temp AS
    (
        SELECT
            reference.DetailPureTitle,
            reference.DetailCaption,
            reference.Nature,
            reference.Summarize
        FROM 
            @CalcsGuids calcs 
        INNER JOIN
            ret_vwPayrollCalculationBackPayForReport details ON details.CalculationGuid = calcs.[Guid] 
        LEFT JOIN 
            ret_PaymentAllocation payment ON payment.Guid = Details.ItemGuid 
        INNER JOIN 
            ret_vwFactorReferences reference ON reference.ItemGuid = Details.ItemGuid 
        INNER JOIN 
            ret_PayrollCalculationCommands command ON command.[Guid] =  details.CalculationCommandGuid
        WHERE
            command.Approved = 1 AND command.Deleted = 0
        GROUP BY
            reference.DetailPureTitle,
            reference.DetailCaption,
            reference.Nature,
            reference.Summarize
    )
    SELECT 
        * 
    FROM
        temp 
    WHERE 
        PayAmount <> 0 OR
        DeductionAmount <> 0 OR
        EmployerAmount <> 0 
    ORDER BY 
        Nature

【问题讨论】：

使用动态 SQL。

@ZoharPeled 很好的提示，我试过了，它奏效了。

INSERT INTO @CalcsGuids EXEC ('SELECT * FROM ' + @CalculationGuidTempTableName);

很高兴为您提供帮助 :-) 请考虑发布问题的答案并在系统允许时接受它，或者删除问题。我敢肯定，如果我们搜索，我们可以在 SO 上找到重复项。

【参考方案1】：

试试这个：

  INSERT INTO @CalcsGuids EXEC ('SELECT * FROM ' + @CalculationGuidTempTableName);
