SQL Oracle合併2查詢

Question

我有這兩個查詢，我必須合併它們，你能幫助我嗎？

select sledovanost.ID_D,tv_stanice.ID_STA,tv_stanice.NAZOV_STANICE 
from sledovanost 
left outer join tv_stanice 
on (sledovanost.id_sta=tv_stanice.id_sta); 

select divak.MENO 
from sledovanost 
left outer join divak 
on (sledovanost.ID_D=divak.ID_D); 

Answer 1

無需瞭解底層的數據結構和期望的結果，最有可能的做法將被鏈接的left join S：

select s.ID_D, t.ID_STA, t.NAZOV_STANICE, d.MENO 
from sledovanost s left outer join 
    tv_stanice t 
    on s.id_sta = t.id_sta left outer join 
    divak d 
    on s.ID_D = d.ID_D;
