SQL：我如何使用条件where子句构造一个select查询？

Question

我想用条件'和'从句执行一个SQL select查询，但遇到了困难。

我愿做这样的事情：

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; 

我该如何去如何组织我的查询做到这一点？

在此先感谢您提供的任何指导。

Answer 1

我认为你可以使用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))
