SSIS 事件处理程序 - 如何获取整个错误消息？答案

【问题标题】：SSIS Event Handler - How do I get the entire error message?SSIS 事件处理程序 - 如何获取整个错误消息？
【发布时间】：2019-12-06 04:13:53
【问题描述】：

我已经使用源组件（ODBC 到 Salesforce）设置了一个数据流任务，该组件将行数和任何引发的错误消息写入表中。

我创建了一个 OnError 事件处理程序，它将消息从 System::ErrorDescription 写入一个变量，然后将该变量写入表中。

我的问题是 System::ErrorDescription 没有有趣的错误消息，而是摘要。这些是在“进度”选项卡中生成的消息：

[SRC - 提取帐户 [6]] 错误：System.Data.Odbc.OdbcException (0x80131937)：错误 [HY000] INVALID_LOGIN：用户名、密码、安全令牌无效；或用户被锁定。等等等等
[SSIS.Pipeline] 错误：SRC - 提取帐户未通过预执行阶段并返回错误代码 0x80131937。

System::ErrorDescription 只有 [SSIS.Pipeline] 错误（“SRC - 提取帐户未通过预执行阶段并返回错误代码 0x80131937”）。如何返回更详细的 [SRC - 提取帐户 [6]] 消息？

谢谢，杰森

您也可以只查询您的 SSISDB 以获取错误。

使用 event_name 查找错误

试试这个：

我知道这个问题很老了，但我今天遇到了这个问题。每个错误消息行都会触发 OnError 事件。因此，要捕获所有错误行，请连接您的变量的值。像这样的东西： Dts.Variables["MyErrorVar"].Value = Dts.Variables["MyErrorVar"].Value + Environment.NewLine + Dts.Variables["System::ErrorDescription"].Value.ToString()
