SQL Server BCP: How to put quotes around all fields?

You need to use CHAR(34) for the quote. This page has more details: http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=153000

Setting the row terminator in addition to the field terminator should do the trick

'bcp DBName..vieter out c:\test003.txt -c -T -t"\",\"" -r"\"\n\"" -S SERVER'

This will likely work, but miss off the leading " for the first field of the first line, and perhaps the last field of the last line - I'm not sure, just guessing really, no server here!

or try using QUOTENAME to wrap text fields (you could also wrap numbers, but that isn't normally required.)

'bcp "SELECT id, age, QUOTENAME(name,'"') FROM DBName..vieter" queryout c:\test003.txt -c -T -t"," -S SERVER'
