如何爲BCP命名列？

Question

我已經在存儲過程中創建了該代碼，它的工作原理類似於一個魅力：但現在我的軟件提供商要求我也包含列名。已經嘗試了幾百個小時，現在總是關閉，但從來沒有取得成功。誰能幫我。

謝謝！

在bcp查詢中使用UNION語句將列名硬編碼到輸出文件中。這意味着您必須將所有內容導出爲varchar/string，因爲每列都將以varchar格式包含其名稱作爲第一個條目。

@sql ='bcp "SELECT 'Detail', 'SectionRelease', '1', 'OrderNumber', 'LineNumber','ItemNumber', 'ActualQuantity', 'UDF01', 'UDF02', 'PickFrom', 'PickingDetail' 
UNION SELECT Detail, SectionRelease, 1, WMS80.dbo.temp_updated.OrderNumber, WMS80.dbo.PickingDetail.LineNumber, WMS80.dbo.PickingDetail.ItemNumber, WMS80.dbo.PickingDetail.ActualQuantity, WMS80.dbo.temp_updated.UDF01, WMS80.dbo.temp_updated.UDF02, WMS80.dbo.PickingDetail.PickFrom FROM WMS80.dbo.temp_updated, WMS80.dbo.PickingDetail WHERE WMS80.dbo.temp_updated.OrderNumber = WMS80.dbo.PickingDetail.OrderNumber" queryout "C:\bcptest.txt" -U user -P password -c -S servername -t,'
