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.'

我在这里找到了答案:http://blog.sqlauthority.com/2007/08/22/sql-server-t-sql-script-to-insert-carriage-return-and-new-line-feed-in-code/

您只需连接字符串并在需要换行符的位置插入CHAR(13)。

例子:

DECLARE @text NVARCHAR(100)
SET @text = 'This is line 1.' + CHAR(13) + 'This is line 2.'
SELECT @text

这将打印出以下内容:

这是直线1。 这是直线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

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:)

我来这里是因为我担心我在c#字符串中指定的cr-lfs没有在SQl Server Management Studio查询响应中显示。

事实证明，它们确实存在，但没有被展示出来。

要“查看”cr-lfs，使用如下的打印语句:

declare @tmp varchar(500)    
select @tmp = msgbody from emailssentlog where id=6769;
print @tmp

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。
