SQL：我如何使用條件where子句構造一個select查詢？

Question

我想用條件'和'從句執行一個SQL select查詢，但遇到了困難。

我願做這樣的事情：

select * from customer 
    where active = true 
    and 
    case 
    when state = 'AK' 
     then zipcode like '%701' 
    when state = 'NV' 
     then zipcode like '%523' 
    else 
     then phone not null; 

我該如何去如何組織我的查詢做到這一點？

在此先感謝您提供的任何指導。

Answer 1

我認爲你可以使用or而不是case。

select * from customer 
where active = true 
and ((state = 'AK' and zipcode like '%701') or (state = 'NV' and zipcode like '%523')) 
and phone is not null; 

Answer 2

你的意思是？

select * from customer 
where active = true 
and ((state = 'AK' and zipcode like '%701') 
    or (state = 'NV' and zipcode like '%523') 
    or (phone not null))
