在Postgres中合併AND OR語句

Question

我想編寫一個查詢，該查詢根據多種不同條件選擇記錄，並使用運算符AND和OR。

例如，如果我編寫以下查詢，我如何保留前兩個條件（network_id = 1 and payment_plan_id = 77）而不在OR聲明之後重寫它們？

select * from transactions where network_id = 1 and payment_plan_id = 
77 and payment_type = 'Subscription' OR payment_type = 'Renewal' 

Answer 1

使用IN避免括號混亂

select * from transactions 
where network_id = 1 
and payment_plan_id = 77 
and payment_type IN ('Subscription' , 'Renewal') 

Answer 2

使用括號：

select * 
from transactions 
where network_id = 1 and payment_plan_id = 77 and 
     (payment_type = 'Subscription' OR payment_type = 'Renewal') 

或者，更好的是，使用in：

select * 
from transactions 
where network_id = 1 and payment_plan_id = 77 and 
     payment_type in ('Subscription', 'Renewal')
