SQL Server：使用批量导出实用程序将数据导出到csv文件时删除换行符

Question

I have a table which I need to export to a csv file. This table has an xml field which can have line breaks that I must remove. I am using the bcp utility to export data from Sql Server to the csv file.

This is the strucutre of the table:

ID int
CODE varchar(20)
XML_DATA xml

This is the command I am using:

bcp "SELECT ID, CODE, replace(convert(nvarchar(max), XML_DATA), CHAR(13)+CHAR(10), ' ') as XML_DATA FROM MYDB.dbo.MyTable" queryout C:\output.csv -c -t0x1F -T -S "10.10.10.28"

For some reasons the output file still contains the line breaks. But if I run the same query on SQL Server for a record which has a line break, the output is correct (line breaks removed):

SELECT
    ID, 
    CODE, 
    replace(convert(nvarchar(max), XML_DATA), CHAR(13)+CHAR(10), ' ') as XML_DATA
FROM MYDB.dbo.MyTable
WHERE ID = 1099; -- record with a line break in the XML_DATA field

What am I missing here?

Answer 1

Solved replacing this line

replace(convert(nvarchar(max), XML_DATA), CHAR(13)+CHAR(10), ' ') as XML_DATA

with this

replace(replace(convert(nvarchar(max), XML_DATA), CHAR(13), ' '), CHAR(10), ' ') as XML_DATA

Also I would like to point out that Sql Server Management Studio by default does not include CLRF characters on copy/paste from a query result, you must explicitly enable an option to preserve CLRF characters and restart SQL Server: preverse CLRF on Sql Server Management Studio query result . That was giving me some confusion ^_^
