Question

以下查询是我从旧应用程序继承的，它将2个属性添加到存储在数据库中的Excel中。

SELECT 
   row_number() over(order by id) as num
   , [id] as mailsort
   , 0 as pages
   , [xmlRecord].query('/sst-statement/*') 
FROM  dbo.RPA200_preproc AS [sst-statement] 
WHERE rpatype = 201 
ORDER BY id for xml auto

返回以

开头的XML

<sst-statement num="1" mailsort="32" pages="0">

现在，SQL需要转换为LINQ语句。这可能与此查询类似，或者从数据库中检索XML然后更改XML会更好吗？

Answer 1

SELECT
row_number() over(order by id) as num,
[id] as mailsort,
0 as pages,
[xmlRecord].query('/sst-statement/*')
FROM  dbo.RPA200_preproc as [sst-statement]
where rpatype = 201
order by id for xml auto

变成了

int i=0;
var Query =
FROM I in dbo.RPA200_preproc
WHERE rpatype = 201
order by id
SELECT I.id;
foreach(var Item in Query)
{
    new XElement("sst-statement", new XAttribute("num", i), new XAttribute("mailsort" = Item), new XAttribute("Pages",(int)0));
    i++;
}

我认为：）

将旧Query格式化为LINQ语句
