我已經在運行一個查詢，但問題是，在 Data/DoctTypes 中有多個 ID，在 Data/Jams/Jam 中有多個 Message、Count、time 列.我已經在表名 XMLFiles 和列名 XMLData 中加載了 xml 文件，現在需要從 xml 文件中檢索 xml 文件中的列，并在單個表中使用它們的值.那么如何檢索這些多列或數據呢?我的查詢如下，

I am already running one query but the problem is that, In Data/DoctTypes there are multiple ID and in Data/Jams/Jam there are multiple Message,Count,time columns. I have already loaded xml files in table name XMLFiles and column name XMLData and now need to retrieve the columns inside xml files from xml files with their values in a single table. So how can I retrieve those multiple Columns or data? My query is below,

Select  XMLData.value('(/Data/BatchNumber)[1]','int' ) BatchNumber,
    XMLData.value('(/Data/ComputerName)[1]','varchar(50)' ) ComputerName,

推薦答案

您的 XML 具有 1:n 關系的嵌套數據.要將其放入正確設計的數據結構中，需要單獨的表.

Your XML has nested data with 1:n relation. To put this in properly designed data structures needs separate tables.

使用此代碼，您將獲得三個帶有生成 ID 的派生表來定義它們的關系:

With this code you would get three derived tables with generated IDs to define their relation:
