返回WHERE條件中使用的子查詢中對象的計數的SQL

Question

如何擴展此SQL查詢（Oracle），以便它還返回所有BROKEN_ITEMS的計數？

select 
    IT.ITEM_ID 
from 
    ITEMS IT 
where 
    IT.ITEM_ID not in (select BI.ITEM_ID 
         from BROKEN_ITEMS BI) 

Answer 1

隨着子查詢：

select 
    IT.ITEM_ID, 
    (select count(*) from BROKEN_ITEMS) BROKEN_ITEMS_COUNT 
from 
    ITEMS IT 
where 
    IT.ITEM_ID not in (select BI.ITEM_ID 
         from BROKEN_ITEMS BI)
