SQL：如何使用条件where子句构造select查询？

我想使用条件'and'子句执行SQL select查询，但遇到困难

我想这样做：

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;

如何构建查询以实现这一点

提前感谢您提供的指导。

您的意思是

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