oracel (列,列) in (值1，值2)的用法

[cheniqit1]

由于有一个excle数据拼接成一个sql语句

如

select  s_landedcost,s_styleno,s_seasonyear,s_seasoncode 
from t_style 
where (s_styleno,s_seasonyear,s_seasoncode) in
 ('NH199','2005','N'
,'NH199','2005','N' );

不知道可以否？

不能这么用.假设
'NH199','2005','N'
'NH199','2005','N'
是某个表t的三个列,c1 , c2 , c3

select m.s_landedcost,m.s_styleno,m.s_seasonyear,m.s_seasoncode
from t_style m
where exists (select 1 from t where m.s_styleno = t.c1 and m.s_seasonyear = t.c2 and m.s_seasoncode = t.c3)

select m.s_landedcost,m.s_styleno,m.s_seasonyear,m.s_seasoncode
from t_style m,t
where m.s_styleno = t.c1 and m.s_seasonyear = t.c2 and m.s_seasoncode = t.c3

[youqi1984]

select s_landedcost,s_styleno,s_seasonyear,s_seasoncode
from t_style
where (s_styleno,s_seasonyear,s_seasoncode) in
(
select 'NH199','2005','N' from dual
union all
select 'NH199','2005','N' from dual
)tb;

不可以这样写的，这样写oracle会报错
下面这样可以

select *
  from emp
 where (job, deptno) in (SELECT JOB, DEPTNO FROM EMP WHERE DEPTNO = 20)
EMPNO ENAME      JOB         MGR HIREDATE          SAL      COMM DEPTNO FLAG
----- ---------- --------- ----- ----------- --------- --------- ------ ----
 7876 ADAMS      CLERK      7788 1987-5-23     1100.00               20 
 7369 SMITH1     CLERK      7912 1980-12-17     800.00               20 
 7566 JONES      MANAGER    7839 1981-4-2      2975.00               20 
 7902 FORD       ANALYST    7566 1981-12-3     3000.00               20 
 7788 SCOTT      ANALYST    7566 1987-4-19     3000.00               20

--可以这样
select s_landedcost, s_styleno, s_seasonyear, s_seasoncode
  from t_style
 where (s_styleno, s_seasonyear, s_seasoncode) in
       (('NH199', '2005', 'N'),( 'NH199', '2005', 'N'));
