blocks|key|1539142|text|T-SQL中的换行符由CHAR(13)和CHAR(10)+(回车符%2B换行符)表示。因此，您可以使用要用来替换换行符的文本来创建一条REPLACE语句。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1539143|REPLACE(MyField,+CHAR(13)+%2B+CHAR(10),+'something+else')|code-block|syntax|javascript|1539144|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

The Newline in T-SQL is represented by CHAR(13) &amp; CHAR(10) (Carriage return + Line Feed). Accordingly, you can create a REPLACE statement with the text you want to replace the newline with.

<pre><code>REPLACE(MyField, CHAR(13) + CHAR(10), 'something else')
</code></pre>

blocks|key|1539209|text|实际上，SQL命令或脚本字符串中的新行可以是CR、LF或CR%2BLF中的任何一行。要获得所有这些内容，您需要这样的内容：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1539210|SELECT+REPLACE(REPLACE(@str,+CHAR(13),+''),+CHAR(10),+'')|code-block|syntax|javascript|1539211|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Actually a new line in a SQL command or script string can be any of CR, LF or CR+LF. To get them all, you need something like this:

<pre><code>SELECT REPLACE(REPLACE(@str, CHAR(13), ''), CHAR(10), '')
</code></pre>

blocks|key|1539274|text|要做大多数人想做的事情，可以创建一个不是真正的换行字符的占位符。然后，您实际上可以将这些方法组合在一起：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1539275|REPLACE(REPLACE(REPLACE(MyField,+CHAR(13)+%2B+CHAR(10),+'something+else'),+CHAR(13),+'something+else'),+CHAR(10),+'something+else')|code-block|syntax|javascript|1539276|这种方法只需替换一次。以下方法：|1539277|REPLACE(REPLACE(MyField,+CHAR(13),+''),+CHAR(10),+'')|1539278|如果您只想去掉CRLF字符，则非常有用，但如果您想要一个占位符，例如|1539279| |1539280|或者别的什么，那么第一种方法会更准确一点。|1539281|entityMap^0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|T|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|U|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|V|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|W|8|@]|9|@]|A|$]]|$1|M|3|N|5|D|7|X|8|@]|9|@]|A|$E|F]]|$1|O|3|P|5|6|7|Y|8|@]|9|@]|A|$]]|$1|Q|3|-4|5|6|7|Z|8|@]|9|@]|A|$]]]|R|$]]

To do what most people would want, create a placeholder that isn't an actual line breaking character. Then you can actually combine the approaches for:
<pre><code>REPLACE(REPLACE(REPLACE(MyField, CHAR(13) + CHAR(10), 'something else'), CHAR(13), 'something else'), CHAR(10), 'something else')
</code></pre>
This way you replace only once. The approach of:
<pre><code>REPLACE(REPLACE(MyField, CHAR(13), ''), CHAR(10), '')
</code></pre>
Works great if you just want to get rid of the CRLF characters, but if you want a placeholder, such as
<pre><code>&lt;br/&gt;
</code></pre>
or something, then the first approach is a little more accurate.

The answer posted above/earlier that was reported to replace CHAR(13)CHAR(10) carriage return:

<pre><code>REPLACE(REPLACE(REPLACE(MyField, CHAR(13) + CHAR(10), 'something else'), CHAR(13), 'something else'), CHAR(10), 'something else')
</code></pre>

Will never get to the <code>REPLACE(MyField, CHAR(13) + CHAR(10), 'something else')</code> portion of the code and will return the unwanted result of:

<pre><code>'something else''something else'
</code></pre>

And NOT the desired result of a single:

<pre><code>'something else'
</code></pre>

That would require the REPLACE script to be rewritten as such:

<pre><code>REPLACE(REPLACE(REPLACE(MyField, CHAR(10), 'something else'), CHAR(13), 'something else'), CHAR(13) + CHAR(10), 'something else')
</code></pre>

As the flow first tests the 1st/Furthest Left REPLACE statement, then upon failure will continue to test the next REPLACE statement.

Sometimes

won't work. In that case use the following snippet code:

I was wanting to sanitize the contents of a column to generate a csv file, so want to get rid of the comma (,) within the varchar as well as newline and carrage-return.
I also wanted to eventually use the generated csv to create another script (to insert rows into another db) so also needed to change ' within the varchar to '' so ended up with this...
<pre><code>REPLACE(REPLACE(REPLACE(REPLACE(ErrorMessage, CHAR(13), ''), CHAR(10), ''),',',''),'''','''''')
</code></pre>
There may be other nicer ways but it got the job done.

I would like to replace (or remove) a newline character in a TSQL-string. 
Any Ideas?

The obvious 

<pre><code>REPLACE(@string, CHAR(13), '')
</code></pre>

just won't do it...

Replace a newline in TSQL

我想替换(或删除)TSQL字符串中的换行符。有什么想法吗？显而易见的REPLACE(@string, CHAR(13), '')就是不会这么做。
