Question

我正在尝试创建包含换行符的文本文件。我有这段代码：

DECLARE @Text AS VARCHAR(100)
DECLARE @Cmd AS VARCHAR(100)

SET @Text = 'This is my text line 1 (supposed to be new line character) This is line2'
SET @Cmd ='echo ' + @Text + ' > C:\FileStore\test.txt'

EXECUTE Master.dbo.xp_CmdShell  @Cmd, NO_OUTPUT

我应该使用什么来在文本文件上添加一个新行，以便输出

This is my text line 1
This is line2

更新我根据建议尝试了这个

SET @Text = 'This is my text line 1' + char(13) + char(10)+ 'This is line2'

但有了这个，它就不再创建txt文件了

由于

Answer 1

使用CHAR（13）输出回车符，或使用CHAR（13）+ CHAR（10）进行回车加换行（对于窗口）

Answer 2

Windows使用回车换行符序列来表示新行，字符代码为13＆amp; 10所以：

select 'hello' + char(13) + char(10) + 'world'

^{（注意，在SSMS网格视图中，您只能看到一个双重空格）}

它不再创建txt文件

啊，echo命令行不支持新行。

你可以

echo This is my text line 1 > "C:\FileStore\test.txt" & echo This is line2 >> "C:\FileStore\test.txt"

或者找到一种不涉及命令行的不同方式。
