用sql中的varchar变量替换“with”e

Question

我试图用"替换&quot，replace(@variable,'"','"')没有帮助，我用XML获取

<tag>&amp quot;Test&amp quot;</tag> 

而不是

<tag>&quot;test&quot;</tag>

示例：

DECLARE @Text varchar(20) = '"Test"'
SET @Text = REPLACE(@Text,'"','&quot ;')
SELECT @Text
DECLARE @Table table (ID int)
INSERT INTO @Table
    (ID)
VALUES
    (123)
DECLARE @TestXml AS XML = ( 
    SELECT
        @Text
    FROM @Table AS tag  
    FOR XML AUTO, ELEMENTS
    )   
SELECT @TestXml

提前致谢

如果问题出在select查询中，请尝试以下sql

更改

SELECT @TestXml

到

SELECT '<tag>' + @TestXml.value('/tag[1]','varchar(max)') + '</tag>'  as 'Word'

您将在选择查询中获得以下结果：

Word
-------------------------------
<tag>&quot;Test&quot;</tag>

<强>更新

保持'＆amp;' char我们需要＆lt;！[CDATA [...]＆gt; 尝试下面的sql

Declare @text nvarchar(20) = '"Test"'
select @text = replace(@text,'"','"')
Declare @table table (ID int)
Declare @xml as nvarchar(Max)

insert into @table values (123)

set @xml=( Select 
    1 as tag,
    Null as Parent,
    @text as [tag!1!!CDATA]
from @table 
for xml Explicit
)

select @xml

结果：

result
---------------------------------------
<tag><![CDATA[&quot;Test&quot;]]></tag>
