Sql Oracle关于语法错误ORA-00907的帮助

当我试图运行与下面类似的代码时，我得到了ORA-00907:missing right paranthesis错误。看来我已经正确地关闭了所有的妄想症

谁能帮我解决这个问题。谢谢

    with cte_tab1 as (
    select 
    tab1.*, 
  case
      when count(distinct Tab1.col_type) over (partition by Tab1.co_new) >1 
        then T_CDR.sales - nvl(T_CDR.profit,0) - nvl(T_CDR.proinf,0) 
      else 0 
  end as rsec_col
  from    tab1
   ),
CV as (
 select
case 
        when tab1.pro_cat in ('RP', 'DE', 'OT', 'CD')          
          then 'TC'
        when tab1.mew = 'TD' and tab1.d_type <> 'BS'
          then 'PREM' 
        else 'TC'
      end as bsspl_new,
sum(nvl(tab1.sales,0)) as gross_sal,
sum(tab1.rsec_col) as seccol
from cte_tab1 as tab1
group by 
case 
        when tab1.pro_cat in ('RP', 'DE', 'OT', 'CD')          
          then 'TC'
        when tab1.mew = 'TD' and tab1.d_type <> 'BS'
          then 'PREM' 
        else 'TC'
      end 
)
select cv.bsspl_new,
cv.gross_sal as gsl,
cv.seccol as ssl
from cv 

从cte_表1作为表1

Oracle中的表别名不支持AS关键字。删除它，您将不会得到错误

将其修改为：

from cte_tab1 tab1
