sql - Postgres : select all row with count of a field greater than 1

Question

我有一个存储产品价格信息的表，该表看起来类似于，(不是主键)

no   name    price    date
1    paper   1.99     3-23
2    paper   2.99     5-25
3    paper   1.99     5-29
4    orange  4.56     4-23
5    apple   3.43     3-11

现在我想选择表中“名称”字段出现不止一次的所有行。基本上，我希望我的查询返回前三行。

我试过:

SELECT * FROM product_price_info GROUP BY name HAVING COUNT(*) > 1  

但我收到一条错误消息:

column "product_price_info.no" must appear in the GROUP BY clause or be used in an aggregate function

Answer 1

SELECT * 
FROM product_price_info 
WHERE name IN (SELECT name 
               FROM product_price_info 
               GROUP BY name HAVING COUNT(*) > 1)
