CSV的SQL Server换行符

Question

I am trying to write a query in CSV format, it is below:

SELECT SUBSTRING
(
    (
        SELECT ',' + [symbol], + ',' + [date] + ',' + [price]
        FROM csvFormatTable
        FOR XML PATH('')
    )
    ,2,200000
) 
AS CSV

and it mostly gives the correct result apart from the ',' at the end of the line but I do want to replace it with a line break. I've seen CHAR(10) and similar stuff like that but it does not give a line break but instead a '#x0D' . The result of the query above is what I have (without the char(10) stuff) below:

symbol,date,price,mikeCode,2019-04-10,50,mikeCode,2019-04-11,200,mikeCode,2019-04-12,10,

Where as it should be:

symbol,date,price
mikeCode,2019-04-10,50
mikeCode,2019-04-11,200
mikeCode,2019-04-12,10

It needs the line break so it can be readable as a CSV.

Assuming you're on SQL Server 2016- then use (N)CHAR(13) and (N)CHAR(10) . You'll then need to use TYPE , to avoid the escaping of the characters, and then value to get the values out.

SELECT STUFF((SELECT ',' + CHAR(13) + CHAR(10) + [symbol] + 
                     ',' + [date] + ',' + [price]
             FROM csvFormatTable
             FOR XML PATH(''),TYPE).value('.','varchar(MAX)'),1,3,'') AS CSV;

If you are on SQL Server 2017+, you can use STRING_AGG

SELECT STRING_AGG(CHAR(13) + CHAR(10) + ',' + [symbol] + ',' + [date] + ',' + [price],CHAR(13) + CHAR(10))
FROM csvFormatTable --Untested

Thanks to @Larnu I changed the settings in my SMSS (link on how to do this is here): How to correctly insert newline in nvarchar

And I just changed my query around a bit to get the wanted results to

    DECLARE @SQL NVARCHAR(MAX)
    SET @SQL =
    '
        DECLARE @test NVARCHAR(MAX)
        SET @test = (SELECT STRING_AGG(CHAR(10) + [symbol] + '','' + [date] + '','' + [price], CHAR(13) ) FROM csvFormatTable)
        SELECT @test
    '

EXEC(@SQL)
