SQL Server 2012 SSRS：使用全局临时表创建报告

我正在使用存储过程创建SSRS报告。存储过程可以动态旋转几次。中间表的模式是动态的，因此我使用临时表。由于该过程使用动态旋转，因此我也少用动态SQL;因此不能在我的脚本中使用本地临时表。存储过程运行正常;但是当同一个存储过程嵌入到SSRS查询设计器中时，它会给出全局临时表已经存在的错误。更不用说，我将它们全部放到代码中。SQL Server 2012 SSRS：使用全局临时表创建报告

请找代码：

可能是报告并行运行？ – TheGameiswar

你的意思是，没有多重连接？ –

我只在查询设计器中出现错误，在初始阶段 –

有几个原因，这个代码是容易发生故障。

通过使用具有相同名称的全局临时表，此过程不能并行运行（不能有重叠的执行）。第二次迭代将尝试创建已经存在的表。
在没有错误处理的情况下放置DROP TABLE语句意味着如果此过程因任何原因失败，则DROP TABLE语句将不会全部执行，从而使临时表以下一次执行的方式执行。这就是抛出你所看到的错误。

，你可以做些什么来解决这个问题（因为你已经做动态SQL）为动态命名的表与在程序开始时确定一个单一的后缀，例如：

DECLARE @TableSuffix NVARCHAR(10)) 
SET @TableSuffix = CAST(ABS(CHECKSUM(NewId())) % 9999999999 AS NVARCHAR(10));

然后为每个表，钉在后缀：

SET @DynamicPivotQuery = 
N'select * into ##Final' + @TableSuffix + 
N' from 
    (SELECT ID, FLOODZONE, New_Version' +' 
    FROM ##Temp' + @TableSuffix + N')SRC 
    PIVOT(MAX(FLOODZONE) 
    FOR New_vERSION IN (' + @ColumnName + ')) AS PVTTable'

你需要让每个全局临时表的创造活力。只要您不打开查询设计器的过程，SSRS应该可以使用动态SQL。绝对避免将过程的DDL作为内联报告SQL。
