SQL 语句提示此处不允许使用分组函数，是哪里错了，谢谢！

select m_name2,m_period_name,m_segment2, m_description3,m_accounted_cr
, sum(m_accounted_dr)
from gx.cw_mxz_1301 m
where m_description3 like '5501%' and chewing (sum(m_accounted_dr))>1000****)
group by m_name2,m_period_name,m_segment2, m_description3,m_accounted_cr

groupby后面应该跟字段名，如果是筛选条件可以使用having关键字

select m_name2,m_period_name,m_segment2, m_description3,m_accounted_cr
,sum(m_accounted_dr)
from gx.cw_mxz_1301 m
where m_description3 like '5501%'
group by m_name2,m_period_name,m_segment2, m_description3,m_accounted_cr
having (sum(m_accounted_dr))>1000****)
