格式化csv文件和powershell

Question

好的，我们有一个手动过程，通过 PL/SQL Developer 运行查询，然后导出到 csv。

由于我们在 Windows 环境中工作，因此我正在尝试使用 powershell 自动化该过程。

我创建了两个似乎与自动和手动过程完全相同的文件，但它们的工作方式不同，所以我假设我缺少一些隐藏字符，但我找不到它们或弄清楚如何删除他们。

它们工作方式不同的最明显示例是在 excel 中打开它们。手动文件在 excel 中打开，自动将每一列放在它自己的单独列中。自动文件将所有内容放在一列中。

有人能解释一下吗？我希望通过解决这个问题或至少获得一些信息将有助于解决无法正确处理的更大问题。

谢谢。

例如一列 "rownum","year","month","batch","facility","transfer_facility","trans_dt","meter","ticket","trans_product","trans","shipper","customer ","供应商","经纪人","原产地","目的地","数量"

ex 单独的列 "","ROWNUM","RPT_YR","RPT_MO","BATCH_NBR","FACILITY_CD","TRANSFER_FACILITY_CD","TRANS_DT","METER_NBR","TKT_NBR","TRANS_PRODUCT_CD","TRANS_CD","SHIPPER_CD" ,"CUSTOMER_NBR","SUPPLIER_NBR","BROKER_CD","ORIGIN_CD","DESTINATION_CD","NET_QTY"

#Write records to file with headers
$records | Select-Object      rownum,year,month,batch,facility,transfer_facility,trans_dt,meter,ticket,trans_product,trans,shipper,customer,supplier,broker,origin,destination,quantity |
ConvertTo-Csv | 
Select -Skip 1|
Out-File $fileLocation

Answer 1

为什么要跳过第一行（通常是标题）？另外，请尝试使用 Export-CSV：

#Write records to file with headers
$records | Select-Object rownum, year, month, batch, facility, transfer_facility, trans_dt, meter, ticket, trans_product, trans, shipper, customer, supplier, broker, origin, destination, quantity |
Export-Csv $fileLocation -NoTypeInformation
