char(13)是CR。对于DOS-/ windows风格的CRLF换行符，你需要char(13)+char(10)，像这样:

'This is line 1.' + CHAR(13)+CHAR(10) + 'This is line 2.'

在某些特殊情况下，你可能会发现这很有用(例如在MS Report中呈现cell-content) 例子:

select * from 
(
values
    ('use STAGING'),
    ('go'),
    ('EXEC sp_MSforeachtable 
@command1=''select ''''?'''' as tablename,count(1) as anzahl from  ? having count(1) = 0''')
) as t([Copy_and_execute_this_statement])
go

char(13)是CR。对于DOS-/ windows风格的CRLF换行符，你需要char(13)+char(10)，像这样:

'This is line 1.' + CHAR(13)+CHAR(10) + 'This is line 2.'

这总是很酷的，因为当您从Oracle获得导出列表时，您将获得跨越几行的记录，这对于cvs文件来说可能很有趣，所以要小心。

无论如何，Rob的答案很好，但我建议使用其他的东西，而不是@，尝试更多的东西，比如§§@@§§或其他的东西，这样它就有一些独特性的机会。(但是仍然要记住你插入的varchar/nvarchar字段的长度..)

下面是一个c#函数，它在现有文本blob之前加上一个文本行，由crlf分隔，并返回适合于INSERT或UPDATE操作的T-SQL表达式。它有一些我们专有的错误处理，但一旦你把它去掉，它可能会有帮助，我希望如此。

    try

                curline = orig_line.Substring(0, iMaxLen - (cum_length + 3));

        } // end foreach(second pass on original lines)

        return(final_comments);

跟着谷歌…

从网站上获取代码:

CREATE TABLE CRLF
    (
        col1 VARCHAR(1000)
    )

INSERT CRLF SELECT 'The quick brown@'
INSERT CRLF SELECT 'fox @jumped'
INSERT CRLF SELECT '@over the '
INSERT CRLF SELECT 'log@'

SELECT col1 FROM CRLF

Returns:

col1
-----------------
The quick brown@
fox @jumped
@over the
log@

(4 row(s) affected)


UPDATE CRLF
SET col1 = REPLACE(col1, '@', CHAR(13))

看起来可以通过用CHAR(13)替换占位符来完成。

问得好，我自己从来没做过:)
