帶有封裝文本字段的BCP/sqlcmd/osql？

Question

可在任何該等命令行工具導出爲.csv，如：

"int_field", "varchar_field", "another_int_field" 
10, "some text", 10 
5, "more text", 1 

等？

我不想使用一個視圖或存儲過程砍在:)

Answer 1

看起來這證實了我的懷疑，答案是：

號

感謝其他建議。

Answer 2

財產以後，雙引號，我已經迅速完成。如果你知道c＃你可以添加它，否則它可能是無用的。不是我最好的代碼，但它正在完成這項工作。所有的字段類型都不在這裏添加，因此需要完成。

內置的工具，做這個SSIS，雖然我明白，不是你想它可能是一個「重」的解決方案，它不是完全Express Edition的支持（你沒有提到任何版本或您正在使用的版本）。您可以在包中的flat file connection manager中定義文本限定符。

或者，用您喜歡的腳本語言編寫一個小腳本。
