如何在ssis中将参数传递给ado.net源？

这是原始查询，使用ado.net源代码并使用源代码中指定的.net providers\odbc数据提供程序可以正常工作

SELECT a.FA_CLNT_ID, a.FA_ACCT_NM, a.ACCT_E_DT, a.POL_PER_CURR_DT, a.POL_PER_NEXT_DT, a.FA_ACCT_NUM, a.GRP_SALES_OFFC_CD, a.ACCT_C_DT   
FROM  gyv2M.DDM_ACCT_STRUC a   
INNER JOIN  
(SELECT max(DDM_ACCT_STRUC_TP) as   DDM_ACCT_STRUC_TP, FA_CLNT_ID 
 FROM gyv2M.DDM_ACCT_STRUC  
 WHERE FA_DM_ROW_DT <= '6/30/2011' AND DM_ROW_E_DT <= '6/30/2011'
 GROUP BY  FA_CLNT_ID) b 
 ON a.DDM_ACCT_STRUC_TP = b.DDM_ACCT_STRUC_TP AND a.FA_CLNT_ID = b.FA_CLNT_ID AND FA_DM_ROW_DT <= '6/30/2011' AND a.DM_ROW_E_DT <= '6/30/2011'

确定您可以使用以下步骤：

将工作查询用于ADO.NET源代码。[无法映射 ADO.NET源代码的参数] 选择数据流并单击属性。 在“属性”窗格中，查找名为Expressions的属性。展开它并单击。。。图标打开下面的属性表达式编辑器屏幕截图。为数据源选择属性SqlCommand，并在您的案例中使用SSIS变量datetime变量使用表达式生成器准备查询。

---

在表达式生成器中尝试此操作-注意，变量必须是字符串，如果不是，则使用DT_WSTR，30来强制转换它。由于您使用的是日期，SQL将需要处理字符串格式的日期，即在Oracle中使用to_date

 "SELECT a.FA_CLNT_ID, a.FA_ACCT_NM, a.ACCT_E_DT, a.POL_PER_CURR_DT, a.POL_PER_NEXT_DT, a.FA_ACCT_NUM, a.GRP_SALES_OFFC_CD, a.ACCT_C_DT   
FROM  gyv2M.DDM_ACCT_STRUC a   
INNER JOIN  
(SELECT max(DDM_ACCT_STRUC_TP) as   DDM_ACCT_STRUC_TP, FA_CLNT_ID 
 FROM gyv2M.DDM_ACCT_STRUC 
WHERE FA_DM_ROW_DT <= '"+ (DT_WSTR,30)@[User::RepDate] +"'  AND DM_ROW_E_DT <= '"+ (DT_WSTR,30)@[User::RepDate] +"' 
 GROUP BY  FA_CLNT_ID) b 
 ON a.DDM_ACCT_STRUC_TP = b.DDM_ACCT_STRUC_TP AND a.FA_CLNT_ID = b.FA_CLNT_ID AND FA_DM_ROW_DT <= '" +(DT_WSTR,30)@[User::RepDate] +"' AND a.DM_ROW_E_DT <='"+(DT_WSTR,30)@[User::RepDate]+"'"

希望这有帮助

在表达式生成器中尝试此操作

 "SELECT a.FA_CLNT_ID, a.FA_ACCT_NM, a.ACCT_E_DT, a.POL_PER_CURR_DT, a.POL_PER_NEXT_DT, a.FA_ACCT_NUM, a.GRP_SALES_OFFC_CD, a.ACCT_C_DT

WHERE FA_DM_ROW_DT <= '"+ (DT_WSTR,30)@[User::RepDate] +"'  AND DM_ROW_E_DT <= '"+ (DT_WSTR,30)@[User::RepDate] +"' 
 GROUP BY  FA_CLNT_ID) b 
 ON a.DDM_ACCT_STRUC_TP = b.DDM_ACCT_STRUC_TP AND a.FA_CLNT_ID = b.FA_CLNT_ID AND FA_DM_ROW_DT <= '" +(DT_WSTR,30)@[User::RepDate] +"' AND a.DM_ROW_E_DT <='"+(DT_WSTR,30)@[User::RepDate]+"'"

希望这能奏效

您是否能够成功计算表达式？如果是这样，请继续并将数据流中的ADO.Net源代码加倍，并选择SQL命令作为数据访问模式-您应该会在那里自动看到查询。可能重复heyy..抱歉，再次更新。我将变量格式更改为字符串，然后尝试按照您给出的方式更改查询。它真的很成功。非常感谢你的帮助。我真的很高兴。如果有任何问题，我们将及时发布。
