Question

我想按<Select style={{ width: "50%", marginBottom: "20px" }} onChange={entry => { this.setState({ select2: entry }); this.onFilteredChangeCustom( entry.value, "firstName" ); }} value={this.state.select2} multi={true} options={this.state.data.map((o, i) => { return { id: i, value: o.firstName, label: o.firstName }; })} />来排序帖子列表，并根据活动或过时将其分组。 id_post，status=1 when active

status=2 when outdated

我尝试使用此mysql代码，但仅显示两个输出。我在做什么错？？

SELECT *,count(id_post) as count
FROM posts
WHERE 1

GROUP BY status
ORDER BY count DESC

预期产量

id_post title status
  5        a     1
  7        b     2
  9        c     1
 17        d     2
 21        f     1

Answer 1

根据您的数据，您无需使用GROUP BY。所以

select *
from posts
order by status ASC, id_post DESC

分组按顺序排序，不能正常工作
