问题描述
美好的一天，我想问一下关于的错误在下面继续下一个
Good day all, I would like to ask a thing about on error resume next
让我们假设我们有一个循环来浏览记录集，如：
let's assume we have a loop to navigate through a recordset like:
Do while not rs.EOF
query = "UPDATE ...."
conn.execute(query)
rs.movenext
loop
我想确保更新正在进行，我想检查是否有一些问题，所以我把调试功能放在代码如下：
i would like to be sure the UPDATE is going good, and i would like to check if there is some problems, so I have put a debugging features in the code like:
Do while not rs.EOF
query = "UPDATE ...."
on error resume next
conn.execute(query)
If Err.Number <> 0 Then
Response.write(Err.Number)
response.write("<br>")
response.write(Err.description)
response.write("<br>")
response.write(query)
response.write("<br><br>")
end if
on error goto 0
rs.movenext
loop
问题是：在循环中，如果遇到错误，下一个循环将会出现错误（因此再次触发错误块）？或错误goto 0 将清除Err对象？
，换句话说，它是否可以作为错误处理？
the question is : during a loop, if it encounters an error, the next cycle will the error be there (and so triggers again the error block) ? or on error goto 0 will clear the Err object?in other words, will it works as a error handling?
推荐答案
VBScript重置 goto 0 ：
VBScript resets the error on goto 0:
on error resume next
i = 1 / 0
WScript.echo( err.number ) '' prints 11 (div by 0)
on error goto 0
WScript.echo( err.number ) '' prints 0 (no error)
还有显式的 err.clear（）。
