Oracle ORA-00933:SQL命令未正确结束00933。00000-“SQL命令未正确结束

当我执行上述两个查询时，它显示SQL命令没有正确结束，可能是因为它们无效；它们是什么

；除和以外的所有红色部分 另一个供应商 应该做什么？注释，也许？在Oracle中，您应该使用-或将注释括在/*…*/

这可能更好一些：

第一个问题：

Select S.sname
From    suppliers s
where not exists (
(select * from parts p where p.color = 'red')  ; all red parts
except
(select c.pid from catalog c, parts p where c.sid = s.sid
and c.pid = p.pid and p.color = 'red'))


select  p.pname
from    parts p. catalog c, suppliers s
where   p.pid = c.pid and c.sid = s.sid
AND s.sname = 'S1'

AND not exists (  # another supplier
select * from catalog c1, suppliers s1
where p.pid = c1.pid and c1.sid = s1.sid
AND s1.sname <> 'S1')

第二个问题：

Select S.sname 
From suppliers s 
where not exists ( (select * 
                    from parts p 
                    where p.color = 'red'
                   ) 
                    minus 
                   (select c.pid 
                    from catalog c, parts p 
                    where c.sid = s.sid 
                      and c.pid = p.pid 
                      and p.color = 'red'
                   )
                 );

您需要使用；加上嵌入的；终止每个语句，所有红色部分和“另一个供应商”也都是错误的，Oracle的SQL中没有例外。注释是通过两个破折号执行的-仅对一行，通过/**/对多行，而不是通过或；

select p.pname 
from parts p, catalog c, suppliers s 
where p.pid = c.pid 
  and c.sid = s.sid 
  AND s.sname = 'S1'
  AND not exists (select * 
                   from catalog c1, suppliers s1 
                   where p.pid = c1.pid 
                     and c1.sid = s1.sid 
                     AND s1.sname <> 'S1'
                 );
