SQL Server通過用戶定義屬性值選擇XML節點

Question

如何通過用戶定義的屬性值獲取xml節點

我想用@pagenumber_替換查詢中的2

Declare @pagenumber_ varchar(max);
Set @pagenumber_ = '2';

Select applicationdata.query('(/applicationdata/page[@number="2"])[1]')  
From Applications

Answer 1

嘗試這個：

CREATE TABLE #Applications
(
    applicationdata XML
);

INSERT INTO #Applications (applicationdata)
VALUES ('<applicationdata><page number="1">page1</page><page number="2">page2</page></applicationdata>')


DECLARE @pagenumber_ VARCHAR(MAX);
SET @pagenumber_ = '2';

SELECT applicationdata.query('(/applicationdata/page[@number=sql:variable("@pagenumber_")])[1]')  
FROM #Applications

DROP TABLE #Applications
