我想在我的存储过程中运行两个选择查询。目前它只运行一个选择查询，但我希望存储过程运行两个选择查询。我要运行的另一个查询是

Select companyUDIDDescription from companyudid where companyKey=@CompanyKey and isDeleted=0

上面的查询返回一个我想在每次执行这个存储过程时使用的列。

    CREATE OR ALTER PROCEDURE [dbo].[GetFilteredUsers]

      @Sitekey   AS INT,
      @CompanyKey   AS INT,

         INTO #TempUsersTable

         WHERE IsDeleted=0 and siteKey=@Sitekey and companyKey=@CompanyKey

【问题讨论】：

这能回答你的问题吗？ Retrieve data from stored procedure which has multiple result sets
如果我在你的团队中看到了Select * from，我会建议你把特定的列都放在星号中
哦，我把*放错了，修正了错误
请注意，您的 @FiterValue 容易受到 sql 注入的影响，因此我希望它已被清理，而不是直接来自用户。

【解决方案1】：

你可以做这样的事情。首先为第一个select语句结果声明一个变量（考虑列名是id）

declare @id int
set @id = (Select id from companyudid where companyKey=@CompanyKey and 
isDeleted=0)

--now you have @id which is the result of the first select statement. and you 
--can use it for the second one in the same procedure
