mysql - 仅返回使用 MySQL DISTINCT 出现一定次数的字段

Question

我正在使用以下查询返回多次出现在表格中的艺术家的姓名，并且第一个字符以 A 开头

SELECT DISTINCT artist FROM releases WHERE artist LIKE 'a%' ORDER BY artist

我现在想更进一步，只想返回出现超过 10 次的艺术家

我该怎么做？

干杯!

Answer 1

最好的方法是使用 aGROUP BY来获取艺术家出现的次数，然后使用HAVING来指示他们至少需要出现一定次数。

我相信这个查询会给你你想要的：

SELECT artist, count(*) 
FROM releases 
WHERE artist LIKE 'a%'
GROUP BY artist 
ORDER BY artist
HAVING count(*) > 10

Answer 2

SELECT artist, count(*)  FROM releases 
WHERE artist LIKE 'a%' GROUP BY artist
ORDER BY artist
HAVING count(*) > 10 

Answer 3

您的查询选择只有艺术家姓名：

select artist from releases
where artist like 'a%' group by artist 
having count(distinct(artist))>10;
