postgresql：SUM与OR运算符和聚合查询

Question

我已成功完成以下查询：

SELECT rs.personid, rs.rec_count,
       sum(case when r.rectype = 'degreeOne' then 1 else 0 end)

但现在我想将此更改为以下

SELECT rs.personid, rs.rec_count,
       sum(case when r.rectype = 'test1' then 1 else 0 end) OR sum(case when r.rectype = 'random' and r.badgeid = 'bronze' then 1 else 0 end) as degree_one, ...

基本上我想和一个"OR"运算符求和，我尝试过，但是它给了我一个错误。

Answer 1

sum (
    case
        when
            r.rectype = 'test1'
            or
            r.rectype = 'random' and r.badgeid = 'bronze'
            then 1
        else 0
    end
) as degree_one
