存储的过程会在SQL Server中提供多个结果集而不是一个结果集

Question

我正在使用SQL Server，并使用SQL Server 2014 Management Studio进行查询。

我正在一个数据库连接中调用一个存储过程，该存储过程给出了多个结果集。

通过“结果集”，我的意思是它给出了多个输出，例如如果我们查询两个select语句，我们将如何获得两个结果集。输出中的行数无关紧要。

这是一个问题，因为如果我在另一个数据库连接中查询它，它只会给出一个预期的结果集。我预计存储过程的任何数据库设置都会出现问题。

P.S。我的过程使用UNION ALL，将所有内容存储在临时表中，然后提供此临时表的输出。

这是我的程序：

    @EffWeekDate DATE
