我有一个bcp命令，它将查询结果推送到以逗号分隔的unicode的平面文件中。我需要将字段封装在双引号中，文本标识符为双引号。
以下是csv输出的示例：
36029,2,Oct 11 2004 1:01AM,4,23537,0.10
需要的地方：
"36029","2","Oct 11 2004 1:01AM","4","23537","0.10"
我怀疑它使用-q标志，但我不确定如何实际使用-q。 MS文档没有做太多帮助我。
对不起，如果这是一个骗局，我发誓，我发誓！

试试这个：
Exec Master..xp_Cmdshell 'bcp "SELECT '"' + col1 + '"', '"' + col2+ '"', '"' + col3+ '"'
FROM table1" queryout "C:\mcg1.csv" -c -t,"'

如果从Eclipse中提取，它会在文本和日期周围添加双引号。我从数据源资源管理器中查看。右键单击 - ＆gt;数据 - ＆gt;提取物...

您还可以使用SQL服务器QuoteName函数来指定应该有引号的列。这也可以添加任何字符代替引号
Exec Master..xp_Cmdshell 'bcp "SELECT QuoteName(col1,Char(34)),QuoteName(col2,Char(34)),... FROM table1" queryout "C:\test.csv" -c -t,"'
