超时在sql server问题中过期

Question

set con2=server.CreateObject("ADODB.Connection")
con2.ConnectionTimeout =1200
con2.open "Driver={SQL Server};server=111.111.111.11;user id=xx;pwd=xxx;Database=xxx"
con2.execute("DELETE FROM tablename WHERE fieldid NOT IN(SELECT fieldid FROM tablename2)")
con2.close
set con2=nothing

当我使用asp运行此查询时发生以下错误。如何解决这个问题？

不使用not in，而是使用left join：

delete from tablename
left join tablename2 on tablename2.fieldid = tablename.fieldid
where tablename2.fieldid is null
