sql - XQuery [nodes()] : Syntax error near '' , 需要一个步骤表达式

Question

运行以下 SQL/XPath 查询会返回以下错误:

查询:

;WITH XMLNAMESPACES (
  'http://schemas.microsoft.com/win/2004/08/events/event' as ns
, default 'http://schemas.microsoft.com/win/2004/08/events/event'
)

select [Events].[Event].value('(./System/TimeCreated/@SystemTime)[1]','nvarchar(100)') EventTime
from @xml.nodes('/*/Event/') [Events]([Event])

错误:

XQuery [nodes()]: Syntax error near '<eof>', expected a step expression.

问题出在 xpath 末尾的 /。即

from @xml.nodes('/*/Event/') [Events]([Event])

应该是:

from @xml.nodes('/*/Event') [Events]([Event])
