试试这个 -

DECLARE @temp1 XML 

SELECT @temp1 = '<?xml version="1.0" encoding="UTF-8"?> 
<processEngine id="5077000" instanceName="bg2-dev.excers"> 
    <controller heartBeat="2014-10-27T15:59:50" /> 
    <loader heartBeat="2014-10-27T16:01:00" queueLength="62" /> 
    <conditionWaitList queueLength="52" /> 
    <retryWaitList queueLength="0" /> 
    <actionWaitList queueLength="0" /> 
    <pipeline heartBeat="2014-10-27T16:01:01" index="4" load="7.216747673537921E-6" name="Pre Condition Pipeline 0" recentLoad="5.963712649181781E-5" runTime="6811" running="false" startTime="2014-10-16T17:59:18" /> 
</processEngine>' 

SELECT 
    a.b.value('@id', 'varchar(10)') value 
FROM 
    @temp1.nodes('/processEngine') a(b)

感谢您的答复，我不能申报像@ temp1中XML，我得到错误 – steve 2014-10-27 11:12:10

哪些错误您收到？ – 2014-10-27 11:13:52

当我在sql服务器中执行此操作时，它仅在第1行显示错误，而且没有显示其他信息 – steve 2014-10-27 11:16:24
