將XML導入到SQL中

Question

我試圖將一些XML導入到SQL中，但它不工作。這是我使用的SQL：

INSERT INTO learnertest (LearnRefNumber, FamilyName,GivenNames) 
SELECT learner.query('LearnRefNumber').value('.', 'VARCHAR(15)'), 
     learner.query('FamilyName').value('.', 'VARCHAR(30)'), 
     learner.query('GivenNames').value('.', 'VARCHAR(30)') 
FROM ( 
SELECT CAST(x AS XML) 
FROM OPENROWSET(
    BULK 'D:\xmltest.xml', 
    SINGLE_BLOB) AS T(x) 
    ) AS T(x) 
CROSS APPLY x.nodes('Message/Learner') AS X(learner); 

這裏是XML

<?xml version="1.0" encoding="utf-8" ?> 
<Message xsi:schemaLocation="http://www.theia.org.uk/ILR/2011-12/1 ILR-2012-13-Structure.xsd" xmlns="http://www.theia.org.uk/ILR/2012-13/1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

     <ALSCost>0</ALSCost> 
     <Dest>97</Dest> 
    </Learner> 
</Message> 

查詢運行沒有錯誤，它只是不插入任何行。任何人都可以解釋我做錯了什麼？

Answer 1

因爲您的Message元素位於namespace中，所以您的xpaths也需要位於該名稱空間中，或者您需要tell SQL to assume a default namespace。後者是在這種簡單情況下更容易的選項：

;WITH XMLNAMESPACES(DEFAULT 'http://www.theia.org.uk/ILR/2012-13/1') 
INSERT INTO learnertest (LearnRefNumber, FamilyName,GivenNames) 
SELECT learner.query('LearnRefNumber').value('.', 'VARCHAR(15)'), 
     learner.query('FamilyName').value('.', 'VARCHAR(30)'), 
     learner.query('GivenNames').value('.', 'VARCHAR(30)') 
FROM ( 
SELECT CAST(x AS XML) 
FROM OPENROWSET(
    BULK 'D:\xmltest.xml', 
    SINGLE_BLOB) AS T(x) 
    ) AS T(x) 
CROSS APPLY x.nodes('Message/Learner') AS X(learner); 

只需添加第一行應該做的伎倆。
