存储过程正在手动运行，但不会使用SQL Server代理运行。
我收到以下错误
以用户身份执行：XXX。 XML解析：第9行，第9个字符，意外 输入结束[SQLSTATE 42000]（错误9400）。步骤失败了。
存储过程从Web查询中获取xml，将其放入临时表中的单个单元格中。解析临时表中的数据，并将新的易读信息放入永久表中。我需要每天运行查询并获取当天的数据。
我已经尝试过查找问题，但我唯一的线索就是XML正在某处被切断。我不知道为什么这只是为了工作而发生的。
你能给予的任何帮助都会很棒。
谢谢
EDIT1：我已将程序分为7个不同的步骤。这是它正在堕落的步骤。

Drop Table #TextData
Drop Table #XMLData
答案 0 :(得分：0)
只是一个更新。这不能正常工作的原因是从网站上获取的XML被截断。我从来没有完全弄清楚为什么会发生这种情况，但是我使用了wget for windows而不是WinHttp.WinHttpRequest.5.1，它从网站上获取了所有数据并将其直接传递到我可以解析数据的网页。
