MySQL 显示值为 NULL 或 IN(2, 3) 的行

Question

我正在尝试查询他们的团队在 15、9、25、26、23、18、12 和 null。问题是查询没有检索到 NULL 记录。

我尝试使用 OR team IS NULL 查询为我提供了所有其他状态。

SELECT e.*,
FROM enquiries e
WHERE e.timestamp BETWEEN '1293840000' AND '1469055599'
  AND e.status IN(1) AND e.team IN(15, 9, 25, 26, 23, 18, 12, NULL)
ORDER BY e.timestamp ASC

请帮忙

Answer 1

将 OR 条件放在括号中

SELECT e.*,
FROM enquiries e
WHERE e.timestamp BETWEEN '1293840000' AND '1469055599'
AND e.status IN(1) AND ( e.team IN (15, 9, 25, 26, 23, 18, 12) OR e.team IS NULL)
ORDER BY e.timestamp ASC
