SSIS包创建.csv文件，添加列但没有行

Question

所以我可以测试OLE DB Source中的连接并连接。

我可以在OLE DB源代码编辑器中预览存储过程。

OLE DB源代码编辑器中的错误输出窗口将错误和截断设置为“失败组件”（我也尝试了其他选项）。

创建.csv文件并添加列标题名称。

但是没有数据行。

EDIT。有人提到我应该包括存储过程。它非常简单，用于测试目的。我确实将“SELECT * FROM tblReport”替换为 “SELECT RPT_ID，RPT_Name，RPT_Description，RPT_DBTimestamp，RPT_Active，RPT_INSDate，RPT_Note FROM tblReport”。我删除了所有未使用的列。

当我在调试模式下运行时，这是我的输出窗口中的新文本。它仍然是相同的，输出列是我期望在Excel文件中看到的那些，但是输出窗口对所有这些列说“没有随后使用”。

另一个编辑：带感叹号的控制流的屏幕打印。 将鼠标悬停在感叹号上会显示： “没有行将被发送到错误输出。配置错误或截断处置以重定向行。” HUH？

Answer 1

确保通向目标的数据流是成功数据流，而不是故障数据流。从您的屏幕截图中可以看出，只有故障数据流才会被映射。

Answer 2

无论是否提供行，都将始终创建目标文件（无论是否出现错误）。

如果需要根据已发送到目标的行获取逻辑，则需要创建SSIS变量并将其附加到行计数转换。在数据流任务之后，您需要根据计数采取措施。有些人选择只使用脚本任务来检查文件，但我觉得更好的做法就是记录我的计数而不是事后检查。
