多列数据集和操作SQL

Question

原始表数据

select 
DTRQLFR.DETERMINATION_ID_FK, DTRQLFR.QUALIFIER_ID_FK, DTRQLFR.QUALIFIER_OPTION_ID_FK 
from IC_DTRMN_QLFR_XREF DTRQLFR 
WHERE 
(DTRQLFR.QUALIFIER_ID_FK, DTRQLFR.QUALIFIER_OPTION_ID_FK) IN ((1,1), (2,3), (3,6)); 

查询结果

我的要求是需要申请一个对数据集第二操作像下面

((1,1) AND (2,3) AND (3,6)) ==> need to find DETERMINATION_ID_FK as 1 
    based on (DTRQLFR.QUALIFIER_ID_FK, DTRQLFR.QUALIFIER_OPTION_ID_FK) values 

预期结果

Answer 1

我认为你正在努力寻找具有所有已知集合的dtrqlfr.determination_id_fk。像这样的东西可以工作：

select 
    DTRQLFR.DETERMINATION_ID_FK 
from IC_DTRMN_QLFR_XREF DTRQLFR 
where 
    (DTRQLFR.QUALIFIER_ID_FK, DTRQLFR.QUALIFIER_OPTION_ID_FK) IN ((1,1), (2,3), (3,6)) 
group by DTRQLFR.DETERMINATION_ID_FK 
having count(*) = 3 -- where 3 is equal to the number of sets 
;
