【问题描述】：

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')

当我执行上述两个查询时，它显示 SQL 命令未正确结束

【问题讨论】：

你需要用; 终止每条语句（加上嵌入的; all red parts 和`#另一个供应商`也是错误的

Oracle 的 SQL 中没有例外。注释掉由两个破折号（--）执行，仅一行，/* */ 执行多行，但不是# 或;

【参考方案1】：

可能是因为它们无效；那些是什么

; all red parts except 和 # another supplier

应该怎么做？评论，也许？在 Oracle 中，您可以使用 -- 或将 cmets 包含在 /* ... */ 中。

这可能更好一些：

第一个查询：

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'
                   )
                 );

第二次查询：

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'
                 );
