SSIS使用ODBC

Question

我正在尝试在OBDC的表达式构建器SQL命令中运行变量。

表达式如下所示

"SELECT Date(Curdate())                   AS 'Load Date', 
       Sum(CASE 
             WHEN pomstatus = 'TBR' 
                  AND Date(portdate) < Curdate() THEN 1 
             ELSE 0 
           END)                          AS 'Total Removes', 
            Min(CASE 
                         WHEN pomstatus = 'TBR' THEN portdate 
                         ELSE 'N/A' 
                       END) AS 'Oldest Removes', 
       Sum(CASE 
             WHEN pomstatus = 'TBR' 
                  AND Date(portdate) < Curdate() 
                  AND Date(portdate) > Subdate(Curdate(),  @[User::Days] )THEN 1 
             ELSE 0 
           END)                          AS 'Total New Removes', 
       Sum(CASE

                  AND acctype = 'b' 
                  AND Date(portdate) < Curdate() THEN 1

                       END) AS 'Oldest Confirmed U', 
       Sum(CASE 
             WHEN pomstatus = 'C-U' 
                  AND discoservice LIKE '%s%' 
                  AND Date(dd) < Curdate()THEN 1

FROM   POM.mainorders 
WHERE  acctype <> 'c';"

我收到以下错误：

错误弹出

我测试了相同的脚本，但用数字2替换了2个变量并且它成功了，所以我知道脚本本身正在工作。在我看来，变量没有正确传递。

至于我如何填充变量，变量将从下面的执行SQL任务填充：

执行SQL任务

执行SQL任务

查询构建器结果

Answer 1

它无法识别字符串

中的变量

尝试将字符串与此连接：

strsplit(letters[i,2], split = "[|]")[[1]]

就个人而言，我会在数据库中创建一个存储过程并传递这两个参数，但不是每个人都有权这样做。

Answer 2

这不是参数如何与执行SQL任务一起使用。

您可以使用字符串连接作为@KeithL建议或将变量（@ [User :: Days]）正确映射到参数（取决于您的提供者 - 基于序数的?标记或命名参数{{1 }}）

由于您的提供程序指示OLE DB，您需要使用@myvalue作为占位符，然后它将成为基于0的序数系统。单击参数映射，参数名称为?，变量为0
