SSIS包创建.csv文件，添加列但不添加行

因此，我可以在OLEDB源代码中测试连接，并将其连接起来

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“Fail Component”（我也尝试了其他选择）

将创建.csv文件并添加列标题名称

但是没有数据行

编辑。有人提到我应该包括存储过程。这对于测试目的来说非常简单。我确实将“从tblReport选择*替换为” “从tblReport中选择RPT_ID、RPT_名称、RPT_描述、RPT_数据库时间戳、RPT_活动、RPT_插入日期、RPT_注释”。我删除了所有未使用的列

这是我在调试模式下运行时输出窗口中的新文本。它仍然是一样的，输出列是我希望在Excel文件中看到的列，但输出窗口对所有列都显示“未随后使用”

另一个编辑：带有感叹号的控制流的屏幕打印。 将鼠标悬停在它显示的感叹号上： “不会将任何行发送到错误输出。请配置错误或截断处理以重定向行。”嗯

无论是否提供行，都将始终创建目标文件（无论是否出错）

如果需要根据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。完成数据流任务后，需要根据计数采取操作。有些人选择只使用脚本任务来检查文件，但我发现在检查时只记录计数而不是事后检查是更好的做法。

确保进入目标的数据流是成功数据流，而不是失败数据流。从您的屏幕截图中可以看出，只有故障数据流被映射通过

发布存储过程有帮助，但不管怎样。。。存储过程可能会产生令人困惑的结果，请确保它始终准确地返回onerecordset，它始终具有相同的元数据，并且您已经启用了

SET NOCOUNT在顶部。查看日志。。。。是否已将SP结果中的列映射到CSV文件？日志中提到的列是否被故意排除在外？由于Error和Truncation设置为“Redirect row”，您需要将这些重定向的行放到某个地方。出于调试的考虑，我建议您选择“fail component”，因为这将产生一个错误，您可以使用它来进行故障诊断。我已经包含了我非常简单的存储过程。它没有在顶部设置计数。我将列映射到CSV文件中。日志中提到的列实际上就是我正在使用的列。我已将“重定向行”更改为“失败组件”。但是仍然不走运。@Nick，请给出您的评论“查看您的上一个屏幕截图，您没有将绿色数据流（成功输出）映射到任何内容”，我会接受它。很公平，非常感谢。现在我知道绿色箭头和红色箭头的用途了。（为我辩护，我电脑上的绿色箭头是深灰色的。哈哈）谢谢你留下来尝试不同的东西。
