错误：没有结果行集与此查询的执行相关联

Question

查询应该作为变量存储在＆＃34;执行SQL任务＆＃34;：

Use [Reporting]
Go

DECLARE 
@current_month DATETIME, 
@current_year DATETIME, 
@current_year_final AS INT, 
@previous_period_final VARCHAR(2),
@test_period AS VARCHAR (2),
@previous_period_final_2 VARCHAR(2)

SET @current_month = DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE()),0)
SET @current_year = DATEADD(YEAR,DATEDIFF(YEAR,0,GETDATE()),0)
SET @current_year_final = CASE WHEN LEFT(RIGHT(CONVERT(VARCHAR, GETDATE(),112),4),2) = '01' THEN LEFT(CONVERT(VARCHAR,@current_year,112),4)-1 ELSE LEFT(CONVERT(VARCHAR,@current_year,112),4) END
SET @previous_period_final = CASE
 WHEN CAST(LEFT(RIGHT(CONVERT(VARCHAR, GETDATE(),112),4),2) AS INT) - 1 BETWEEN 10 AND 11 THEN  CAST(CAST(LEFT(RIGHT(CONVERT(VARCHAR, GETDATE(),112),4),2) AS INT) - 1 AS VARCHAR)  -- Type Varchar
 WHEN CAST(LEFT(RIGHT(CONVERT(VARCHAR, GETDATE(),112),3),1) AS INT) - 1 BETWEEN 1  AND 8  THEN '0' + CAST(CAST(LEFT(RIGHT(CONVERT(VARCHAR, GETDATE(),112),3),1) AS INT) - 1 AS VARCHAR)
 WHEN CAST(LEFT(RIGHT(CONVERT(VARCHAR, GETDATE(),112),4),2) AS INT) - 1 = 9 THEN '09'
 WHEN      LEFT(RIGHT(CONVERT(VARCHAR, GETDATE(),112),4),2) = '01'          THEN '12'
 ELSE 'Invalid formula' END
SET @previous_period_final_2 = CAST(LEFT(RIGHT(CONVERT(VARCHAR, GETDATE(),112),4),2) AS INT) - 1 

-- ### Returns: 
--    1 = 'identical' = row numbers match
--    0 = 'mis-matched' = row numbers do not match
select sum(rows_identical) as rows from

 and SourceID IN (select SourceID from dbo.dim_source where Source = 'Unlocks')

union

   select COUNT(ID) as #rows_facts, 'missing_entries_facts_table' as type from missing_ids_Unlocks_raw 
 where YearMonthID in (select YearMonthID from dim_year_month as yyMM  
        where yyMM.YearMonth = CAST(@current_year_final AS Varchar)+'_'+CAST(@previous_period_final AS Varchar))
 and SourceID IN (select SourceID from dbo.dim_source where Source = 'Unlocks')         
  ) as rows
 ) as count_rows_facts,
 (
SELECT count(*)as #rows_raw from UnlocksRawCSV_table as raw

SSIS中的变量定义和结果集映射：

在执行SQL任务中，我选择了＆＃34;结果集=单行＆＃34;。我也试过＆＃34;无＆＃34;。我在执行SQL任务上放了一个后执行断点，然后得到：

==如果我直接在SQL Server中执行此查询（见上文），我获得1时，为什么我在SSIS中获得0值？

后续任务中的优先约束如下所示：

编辑1：将此表达式更改为@RowCheck == 0不会改变任何内容，因为执行时任务仍然失败并出现相同的错误：

  

错误：没有结果行集与此查询的执行相关联

编辑：2：更改优先约束编辑器中的值＆＃34;成功＆＃34;到＆＃34;失败＆＃34;有效，但我不明白为什么任务本身失败以及为什么它会产生上述错误信息？但是，尽管继续使用包，但为变量RowCheck显示的值没有任何意义，因为它始终为零，无论Query返回...

编辑3：执行SQL语句的常规选项卡屏幕（我也尝试了＆＃34;单行＆＃34;以及上面提到的结果集映射：
