sql - POSTGRESQL 中同一行的两个结果

Question

select * from Table1
where Condition 1
union 
select select * from Table1
where Condition 2

---

结果:

NAME    AMOUNT    TYPE   
ABC      --       Account
ABC      200        --

---

但我需要像这样的一行中的结果

NAME     AMOUNT     TYPE
ABC       200       ACCOUNT

---

PG怎么办？

Answer 1

根据您的示例数据，这可能有效

SELECT name,
       MAX(amount) amount,
       MAX(type) type
  FROM table1
 WHERE condition 1
    OR condition 2
 GROUP BY name
