以CSV格式導出數據表sql server 2008

Question

我需要創建一個存儲過程來查詢表併爲指定目錄位置中的數據創建一個CSV文件。

我該怎麼做？

Answer 1

您無法直接使用存儲過程。我建議在SQL Server Management Studio中右鍵單擊數據庫，然後選擇「導出數據」。

爲它提供一個查詢或返回行的存儲過程。告訴它你希望文件由逗號和用引號限定的文本分隔。

當嚮導詢問您是要執行還是保存時，請將其保存到磁盤。

這使得所謂的SSIS包。然後，您可以使用Windows資源管理器來運行它，或者使用名爲dtexec.exe的命令行程序來運行它，或者將它提供給DBA，讓它們在SQL Server中運行它。

Answer 2

您可以通過exec調用BCP的xp_cmdshell 'BCP dbname..table出filename.bcp .....'

這是一個非常類似的問題，除了它的進口。 Use bcp to import csv file to sql 2005 or 2008

See here for more information on BCP.

Answer 3

這是可能做到，但你需要有足夠的權利來運行xp_cmdshell和即席分佈式查詢。
