使用执行 SQL 脚本在 SSIS 中加载日期变量时出错

Question

我正在尝试使用 SSIS 中的执行 SQL 任务填充变量。表结构如下：

CREATE TABLE BuildControl 
(Id INT NOT NULL Identity, BuildDate Date, 
     Country char(2), BuildStatus varchar(20), 
     BuildStatusDate DateTime)

SQL 语句是

SELECT TOP 1 ? = Id, ? = BuildDate
FROM BuildControl
WHERE BuildStatus IS NULL
ORDER BY Id

如果我删除? = BuildDate. 参数映射选项卡如下所示：

我收到的错误是这样的：

SSIS package "WFG Statement Build.dtsx" starting.
Error: 0xC002F210 at Get Build Data, Execute SQL Task: Executing the query "SELECT TOP 1 ? = Id, ? = BuildDate
FROM BuildContr..." failed with the following error: "Error HRESULT E_FAIL has been returned from a call to a COM component.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
Task failed: Get Build Data
Warning: 0x80019002 at WFG Statement Build: SSIS Warning Code DTS_W_MAXIMUMERRORCOUNTREACHED.  The Execution method succeeded, but the number of errors raised (1) reached the maximum allowed (1); resulting in failure. This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors.
SSIS package "WFG Statement Build.dtsx" finished: Failure.

我相信问题出在日期输出变量上，因为当我删除它时我没有问题。我使用的服务器和 SSIS 版本都是 SQL Server 2008 R2。连接管理器是使用Native OLE DB\SQL Server Native Client 10.0提供程序的 OLE DB 连接。我尝试更改表结构以使用 DateTime 没有成功，并尝试在参数映射页面中将 DBDate 和 DBDateTime 作为数据类型也没有成功。

我完全不知所措。谢谢你的帮助！

尝试映射您的结果集，而不是参数。设置类似；在您的选择语句中，结果名称是0和1并且? =不是必需的。

SELECT TOP 1 Id, BuildDate
FROM BuildControl
WHERE BuildStatus IS NULL
ORDER BY Id

此外，请确保您的结果集设置为Single row。
