无法确定元数据,因为语句“插入”

sql

我有一条select语句,在其中创建了2个临时表并在select插入之前进行插入,然后从这些临时表中获取数据,从而在它们之间建立连接。我希望元数据成为最终选择。在ssms中,它运行良好,在ssis中,我不知道为什么会抛出该错误。查询是这样的:

CREATE TABLE #Per (PerID bigint NOT NULL......)
CREATE TABLE #Pre (PerID bigint NOT NULL, IsWorking.......)
INSERT INTO #Per SELECT .... FROM .....
INSERT INTO #Pre SELECT .... FROM .....
SELECT * FROM #Per per LEFT JOIN #Pre pre ON per.PerID = pre.PerID

我已经测试了所有语句以确保它们和整个查询正常工作,并向我返回了数据,但是ssis抛出了错误:

The metadata could not be determined because statement 'INSERT INTO #Per SELECT ...... uses a temp table.".
Error at project_name [646]: Unable to retrieve column information from the data source. Make sure your target table in the database is available.

尝试使用表变量代替类似:

DECLARE @Per TABLE (PerID bigint NOT NULL......)
DECLARE @Pre TABLE (PerID bigint NOT NULL, IsWorking.......)
INSERT INTO @Per SELECT .... FROM .....
INSERT INTO @Pre SELECT .... FROM .....
SELECT * FROM @Per per LEFT JOIN @Pre pre ON per.PerID = pre.PerID

应该工作正常
