Question

我的SSIS中的Send mail task（基于Visual Studio 2008）软件包（CodaRawDataUpload.dtsx）未被触发（它根本不会变为绿色，黄色或红色）。

SSIS控制流程

“Row Check”命令中的SQL返回0或1，并定义为int。结果rows_identical被定义为具有Int32数据类型的变量。

SQL看起来像这样：

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 

select CAST(CAST(case when count_rows_raw = count_rows_facts then 1 else 0 end as bit)as int) as rows_identical 
--,SQL_VARIANT_PROPERTY(CAST(CAST(case when count_rows_raw = count_rows_facts then 1 else 0 end as bit)as int),'BaseType') -- ### EXCELLENT WAY TO RETRIEVE DATATYPE ###

        ) as rows
    ) as count_rows_facts,

as row_checks

在SQL任务设置中，我使用了这个变量，如下所示：

至于Precedence Constraint Editor我尝试了两种方式（值= 0或值= 1）但是从不触发发送邮件任务：

为什么呢？这有什么问题？

编辑：添加断点时添加了屏幕
