Question

我是SQL Server中的XML新手。

我有这样的查询

declare @EstimateType char(1)

select top 1
    ISNULL((case when @EstimateType='x' or @EstimateType='C' then
SUBSTRING((select ',' + ItemTitle from tb_Pricecatalogue WHERE PricecatalogueID IN(select PricecatalogueID from tb_DeliveryItem WHERE PriceCatalogueID = 0 )
FOR XML PATH('')),2,8000) 
WHEN ISNULL((select top 1 et.ItemID FROM tb_DeliveryItem et WHERE et.DeliveryItemID = 252602 AND isdeleted = 0 ),0)>0 THEN
 SUBSTRING((select ',' + ItemTitlevalue from tb_EstItemDescription WHERE EstimateItemID=
 (246666)  FOR XML PATH('')),2,8000) END),'') as ItemTitle    

from tb_DeliveryItem d  
where DeliveryItemID=252602 AND IsDeleted=0

将xml返回为

A4 PUR Bound Booklet - 4pp Cover + 116pp Text&lt;br/&gt;&lt;br/&gt;&lt;br/&gt;

如何将>替换为>，将<替换为<？

看起来可以使用TYPE Directive

来实现

我已修改查询以在TYPE旁添加FOR XML PATH('')指令的用法

DECLARE @EstimateType char(1)

SELECT TOP 1
ISNULL((
CASE WHEN @EstimateType='x' OR @EstimateType='C' THEN
    SUBSTRING(( SELECT ',' + ItemTitle FROM tb_Pricecatalogue 
                WHERE PricecatalogueID IN ( SELECT PricecatalogueID 
                                            FROM tb_DeliveryItem 
                                            WHERE PriceCatalogueID = 0 )
                FOR XML PATH(''), TYPE),2,8000)
    WHEN ISNULL((SELECT TOP 1 et.ItemID 
                FROM tb_DeliveryItem et 
                WHERE et.DeliveryItemID = 252602 
                AND isdeleted = 0 ),0)>0 THEN
    SUBSTRING(( SELECT ',' + ItemTitlevalue 
                FROM tb_EstItemDescription 
                WHERE EstimateItemID= (246666) FOR XML PATH(''), TYPE),2,8000) END),'') as ItemTitle    
FROM tb_DeliveryItem d  
WHERE DeliveryItemID=252602 AND IsDeleted=0

希望这有帮助！

在SQL Server存储过程中将“＆lt;”和“＆gt;”替换为“＆lt;”和“＆gt;”
