MySQL选择某些变量

Question

我对MySQL很新，我目前只想显示变量“活动”等于多个条目的数据：壁画，音乐会，剧院和博物馆。我该怎么做？

SELECT * FROM trail101 ORDER BY id DESC LIMIT 0, 9

Answer 1

你需要使用WHERE条款。漫长的道路：

SELECT * FROM trail101 WHERE
    activities = 'murals' OR
    activities = 'concert' OR
    activities = 'theater' OR
    activities = 'museums'
    ORDER BY id DESC LIMIT 0, 9

或者与IN：

SELECT * FROM trail101
    WHERE activities IN('murals', 'concert', 'theater', 'museums')
    ORDER BY id DESC LIMIT 0, 9
