如何从sql server中的数据表的列中获取字符串数据

Question

您好我想在选择查询中将＆amp;＃x0A转换为＆amp;＃x0D＆amp;＃x0A

SELECT TOP 1  
 @F0 = ID,  
 @F1 = MessageSource,  
 @F2 = MessageID,  
 @F3 = MessageText  
FROM [dbo].[sample_MESSAGE]  
WHERE MessageStatus = 'FR' and MessageSource=@Param1   -- VALID  --Lavanya

SELECT @F0 AS F0, @F1 AS F1, @F2 AS F2, replace(@F3,'
','
') AS F3  
FOR XML RAW

但它没有取代我指定的值，任何人都可以在此建议我

Answer 1

也许你的意思是：

  … REPLACE(@F3, CHAR(10), CHAR(13) + CHAR(10)) AS F3 …

或者这个：

  … REPLACE(@F3, NCHAR(10), NCHAR(13) + NCHAR(10)) AS F3 …

取决于@F3是varchar还是nvarchar。

Answer 2

有效：

DECLARE @F0 INT, @F2 INT, @F1 INT, @F3 VARCHAR(MAX)
SELECT 
 @F0 = 1,  
 @F1 = 2,  
 @F2 = 3,  
 @F3 = '
'  


SELECT @F0 AS F0, @F1 AS F1, @F2 AS F2, replace(@F3,'
','
') AS F3  
FOR XML RAW

所以

你必须找出文本数据中的不良内容。如果文字包含代码为10的字符，则不应让REPLACE查找字符串'
'将CHAR(10)替换为CHAR(10)_CHAR(13)而不是
