在线程中创建异常挂钩

Question

当我把它放在主模块中时，下面的代码运行良好，但是当线程中发生错误时不会调用异常钩子，即使我在代码中第二次放入代码也没有。

有什么建议吗？

create function [dbo].[udf_splitstring] (@tokens    varchar(max),
                                         @delimiter varchar(5))
returns @split table (
  token varchar(200) not null )
as
  begin
      declare @list xml

      select @list = cast('<a>'
                          + replace(@tokens, @delimiter, '</a><a>')
                          + '</a>' as xml)

      insert into @split
                  (token)
      select ltrim(t.value('.', 'varchar(200)')) as data
      from   @list.nodes('/a') as x(t)

      return
  end


  create table #dup
( id int, name varchar(100)
)
insert into #dup values
(1,'leela,venkatesh,don'),
(2,'john,smith,lewis')

select id,b.token from #dup
cross apply 
(select token from  udf_splitstring(name,',') )b

线程调用如下：

import sys
def myexcepthook(exctype, value, traceback):
    if exctype == KeyboardInterrupt:
        print "Handler code goes here"
    else:
        sys.__excepthook__(exctype, value, traceback)

sys.excepthook = myexcepthook
