QQ传SQL语句出现的问题:

QQ传SQL语句出现的问题:

通过QQ传数据数据内容如下:
select * from  vw_inout_signfor
where  project_code='0000000027'
  and isnull(lastnum,0)<>0
  and billtypen='2'
  and uf_flag='采购结算'
  and isnull(outnum,0)=0
  and itemname not like '%水泥%'
我现在加批注
select * from  vw_inout_signfor
where  project_code='0000000027'
  and isnull(lastnum,0)<>0--
  and billtypen='2'
  and uf_flag='采购结算'
  and isnull(outnum,0)=0
  and itemname not like '%水泥%'

那么运行的语句为:
select * from  vw_inout_signfor
where  project_code='0000000027'
  and isnull(lastnum,0)<>0
但未通过QQ传,,得到的结果正常..

所以告诉各位...没事不要用QQ传SQL语句...不然造成什么语法错误..找问题找半天也找不到.
